Serial Input / Output Timing
1. Data is taken by DI sync with the rise of SK.
2. At read operation, data is output from DO in sync with the rise of SK.
3. The STATUS signal at write (READY / BUSY) is output after tCS from the fall of CS after write command input, at the area
DO where CS is high, and valid until the next command start bit is input. And, while CS is low, DO becomes High-Z.
4. After completion of each mode execution, set CS low once for internal circuit reset, and execute the following operation
mode.
5. 1/fSK is the SK clock cycle, even if fSK is maximum, the SK clock cycle can’t be tSKH(Min)+tSKL(Min)
6. For “Write cycle time tE/W”, please see Figure 36,37,39,40.
7. For “CS low time tCS”, please see Figure 36,37,39,40.

Description of Operations
Communications of the MicroWire BUS are carried out by SK (serial clock), DI (serial data input),DO (serial data output) ,and
CS (chip select) for device selection.
When connecting one EEPROM to a microcontroller, connect it as shown in Figure 34(a) or Figure 34(b). And when using
the input and output common I/O port of the microcontroller, connect DI and DO of EEPROM via a resistor as shown in
Figure 34(b) (Refer to pages 21, 22.), wherein connection by 3 lines is possible.
In the case of connecting multiple EEPROM devices, refer to Figure 34 (c).
Communications on MicroWire BUS is started by the first “1” input after the rise of CS. This input is called the “Start Bit”.
After the start bit, the Ope code, address and data are then inputted sequentially. Address and data are all inputted with MSB
first.
“0” inputs from the rise of CS to the start bit input are all ignored. Therefore, when there is limitation in the bit width of PIO of
the microcontroller, input “0” before the start bit input, to control the bit width.

Timing Chart
1. Read Cycle (READ)
(1) Start bit
After the rising edge of CS, the first data “1” input will be recognized as the start bit and the following operation starts. All “0s” preceding the start bit
are ignored. This applies to all command that will be discussed later.
(2) For the meaning of Am,Dx,n,please see tables of command mode in Page15. For example, ORG=H or OPEN,Am=A7,Dx=D15,n=27.
(1) When the READ command is received, data is clocked out to DO synchronously with the rising edge of SK. A “0”
(dummy bit) is output first in sync with the address bit A0. Then follows the 16-bit data from the selected address
MSB first.
This IC has an Address Auto Increment function that is available only for READ command. After the first 16-bit data
has been output to DO and CS is kept High, a continuous SK clock input causes the address to increment
automatically and the IC outputs a stream of successive data from consecutive addresses.
2. Write Cycle (WRITE)
For the meaning of Am,Dx,n, please see tables of command mode in Page15.
(1) In this command, input 16bit or 8bit data are written to designated addresses (Am to A0). The actual write starts by
the fall of CS of D0 taken SK clock.
When STATUS is not detected (CS=low fixed),make sure Max 5ms time is in comforming with tE/W.
When STATUS is detected (CS=high), all commands are not accepted for areas where low (BUSY) is output from
DO, therefore, do not input any command.
3. Write All Cycle (WRAL)
For the meaning of Dx,n,please see tables of command mode in Page15.
(1) In this command, input 16bit or 8bit data is written simultaneously to all adresses. Data is not written continuously
per one word but is written in bulk, the write time is only Max 5ms in conformity with tE/W.
In WRAL, STATUS can be detected in the same manner as in WRITE command.

4. Write Enable (WEN) / Disable (WDS) Cycle
For the meaning of n,please see tables of command mode in Page15.
(1) At power on, this IC is in write disable status by the internal RESET circuit. Before executing the write command, it
is necessary to execute the write enable command. And, once this command is executed, it is valid unitl the write
disable command is executed or the power is turned off. However, the read command is valid irrespective of write
enable / diable command. Input to SK after 6 clocks of this command is available by either “1” or “0”, but be sure to
input it.
(2) When the write enable command is executed after power on, write enable status gets in. When the write disable
command is executed then, the IC gets in write disable status as same as at power on, and then the write command
is canceled thereafter in software manner. However, the read command is executable. In write enable status, even
when the write command is input by fault, write is started. To prevent such error, it is recommended to execute the
write disable command after completion of write.
5. Erase Cycle (ERASE)
For the meaning of Am,n,please see tables of command mode in Page15.
(1) In this command, data of the designated address is made into “1”. The data of the designated address becomes
“FFFFh or FFh”.
Actual ERASE starts at the fall of CS after the fall of A0 taken SK clock.
In ERASE, STATUS can be detected in the same manner as in WRITE command.
6. Erase All Cycle (ERAL)
For the meaning of n,please see tables of command mode in Page15.
(1) In this command, data of all addresses is made into “1”. Data of all addresses becomes ”FFFFh or FFh”.
Actual ERASE starts at the fall of CS after the falll of the n-th clock from the start bit input.
In ERAL, STATUS can be detected in the same manner as in WRAL command.

2. At Standby
When CS is low and ORG is high or OPEN, even if SK,DI, DO are low, high or with middle electric potential, current
does not exceed ISB1 Max

3. I/O Peripheral Circuit
(1) Pull Down CS.
By making CS=low at power ON/OFF, wrong operation and write error are prevented.
(a) Pull Down Resistance RCS of CS Pin
To prevent wrong operation and write error at power ON/OFF, CS pull down resistor is necessary. Select an
appropriate resistor value from microcontroller VOH, IOH, and VIL characteristics of this IC.
(2) DO is available in both pull up and pull down.
DO output always is High-Z except in READY / BUSY STATUS and data output in read command.
When malfunction occurs at High-Z input of the microcontroller port connected to DO, it is necessary to pull down
and pull up DO. When there is no influence upon the microcontroller operations, DO may be left OPEN.
If DO is OPEN during transition of output from BUSY to READY status, and at an instance where CS=high,
SK=high, DI=high, EEPROM recognizes this as a start bit, resets READY output, and sets DO=High-Z. Therefore,
READY signal cannot be detected. To avoid such output, pull up DO pin for improvement.

(a) Pull Up Resistance RPU and Pull Down Resistance RPD of DO pin
As for pull up and pull down resistance value, select an appropriate resistor value from microcontroller VIH, VIL,
and VOH, IOH, VOL, IOL characteristics of this IC.
(b) READY / BUSY STATUS display (DO terminal)
This display outputs the internal STATUS signal. When CS is started after tCS
from CS fall after write command input, high or low is output.
R/B displaylow (BUSY) = write under execution
After the timer circuit in the IC works and creates the period of tE/W, this timer circuit completes automatically.
And the memory cell is written in the period of tE/W, and during this period, other command is not accepted.
R/B display = high (READY) = command wait STATUS
After tE/W (Max5ms) the following command is accepted.
Therefore, CS=high in the period of tE/W, and If signals are input in SK, DI, malfunction may occur,
therefore, DI=low in the area
CS=high. (Especially, in the case of shared input port, attention is required.)
*Do not input any command while STATUS signal is active. Command input in BUSY area is cancelled, but command input in READY area is accepted.
Therefore, STATUS READY output is cancelled, and malfunction and write error may occur.

4. When to Directly Connect DI and DO
This IC has independent input terminal DI and output terminal DO, wherein signals are handled separately on timing chart.
But, by inserting a resistance R between these DI and DO terminals, it is possible to carry out control by a single control
line.
Data collision of microcontroller DI/O output and DO output and feedback of DO output to DI input of EEPROM.
Drive from the microcontroller DI/O output to DI input of EEPROM on I/O timing, and output signal from DO output of
EEPROM occur at the same time in the following points.
(1) 1 Clock Cycle to take in A0 Add re ss Data at Read Command
Dummy bit “0” is output to DO terminal.
When address data A0 = “1” input, through current route occurs.
(2) Timing of CS = high after write command. DO terminal in READY / BUSY function output.
When the next start bit input is recognized, High-Z gets in.
Especially, at command input after write, when CS input is started with microcontroller DI/O output low,
READY output high is output from DO terminal, and through current route occurs.
Feedback input at timing of these (1) and (2) does not cause disorder in basic operations, if resistance R is inserted.
Note) As for the case (2), attention must be paid to the following.
When STATUS READY is active, DO and DI are shared, DI=high and the microcontroller DI/O=High-Z or the microcontroller DI/O=high,if SK clock
is input, DO output is input to DI and is recognized as a start bit, and malfunction may occur. As a method to avoid malfunction, at STATUS READY
output, set SK=low, or start CS within 4 clocks after high of READY signal is output.

Selection of Resistance Value R
The resistance R becomes a short-circuit current limiting resistance during signal conflicts and it does not affect the
basic operations of the device. When short-circuit current flows, glitches in the power source lines may be produced.
Determine the maximum transient current in the power lines wherein glitches are not produced. Select the value of
resistance R that will satisfy the EEPROM input level VIH/VIL, even under the influence of voltage fluctuations resulting
from short-circuit current and so forth. Assuming the allowable short-circuit current defined as I, the following relation
should be satisfied.
(3) Address Data A0 = “1” input, dummy bit “0” Output Timing
(When microcontroller DI/O output is high, EEPROM DO outputs low, and high is input to DI)
(a) Make the through current to EEPROM 10mA or below.
(b) See to it that the level VIH of EEPROM should satisfy the following.
(4) DO STATUS READY Output Timing

5. I/O Equivalence Circuit
6. Power-Up/Down Conditions
(1) At pow er ON/OFF, set CS low.
When CS is high, this IC gets in input accept status (active). At power ON, set CS low to prevent malfunction and
write error from noise (When CS is in low status, all inputs are cancelled.). At power decline, low power status may
prevail.
Therefore, at power OFF, set CS low to prevent malfunction from noise.
(2) POR Circuit
This IC has a POR (Power On Reset) circuit as a write error countermeasure. After POR operation, it gets in write
disable status. The POR circuit is valid only when power is ON, and does not work when power is OFF. However, if
CS is high at power ON/OFF, it may become write enable status owing to noises and the likes. For secure
operations, observe the following conditions.
(a) Set CS=low
(b) Turn on power so as to satisfy the recommended conditions of tR, tOFF, Vbot for POR circuit operation.
(3) LVCC Circuit
LVCC (Vcc-Lockout) circuit prevents data rewrite operation at low power, and prevents wrong write.
At LVCC voltage (Typ=1.2V) or below, it prevents data rewrite .

7. Noise Countermea sures
(1) VCC Noise (Bypass Capacitor)
When noise or surge gets in the power source line, malfunction may occur. Therefore, in removing these, it is
recommended to connect a bypass capacitor (0.1μF) between IC VCC and GND, At that moment, connect the
capacitor as close to IC as possible. And, it is also recommended to connect a bypass capacitor between board
VCC and GND.
(2) SK Noise
When the rise time of SK is long, and a certain degree or more of noise exists, malfunction may occur owing to
clock bit displacement. To avoid this, a Schmitt trigger circuit is built in SK input. The hysteresis width of this circuit
is set about 0.2V, if noises exist at SK input, set the noise amplitude 0.2Vp-p or below. And it is recommended to set
the rise time of SK 100ns or below. In the case when the rise time is 100ns or higher, take sufficient noise
countermeasures. Make the clock rise, fall time as small as possible.

Operational Notes
1. Described numeric values and data are design representative values only, and the values are not guaranteed.
2. We believe that application circuit examples are recommendable. However, in actual use, confirm characteristics further
sufficiently. In the case of use by changing the fixed number of external parts, make your decision with sufficient margin
in consideration of static characteristics and transition characteristics and fluctuations of external parts and our IC.
3. Absolute maximum ratings
If the absolute maximum ratings such as supply voltage and operating temperature and so forth are exceeded, LSI may
be destroyed. Do not supply voltage and temperature exceeding the absolute maximum ratings. In the case of fear
exceeding the absolute maximum ratings, take physical safety countermeasures such as fuses, and see to it that
conditions exceeding the absolute maximum ratings should not be supplied to LSI.
4. GND electric potential
Set the voltage of GND terminal lowest at any operating condition. Make sure that each terminal voltage is not lower
than that of GND terminal at any time, even during transient condition.
5. Thermal design
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in
actual operating conditions.
6. Short between pins and mounting errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong
orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the
pins.
7. Operating the IC in the presence of strong electromagnetic field may cause malfunction, therefore, evaluate design
sufficiently.
