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. After completion of each mode execution, set CS low once for internal circuit reset, and execute the following operation mode. 1/fSK is the SK clock cycle, even if fSK is maximum, the SK clock cycle can't be tSKH(Min)+tSKL(Min) For "Write cycle time tE/W", please see Figure 36,37,39,40.

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). SK SK SK DO DI DI DO BR93GXX CS SK DI/O DI DO (a). Connection by 4 Lines CS3 CS2 CS1 SK DO DI (b).

Connection Example of Multiple Devices Figure 34. Connection Method with Microcontroller 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.

For example, ORG=H or OPEN,Am=A7,Dx=D15,n=27. Figure 35. Read Cycle (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.

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.

Figure 38. Write Enable (WEN) / Disable (WDS) Cycle (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.

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. VOHM Rcs Microcontroller EEPROM VOHM High output VOHM Rcs VIHE Example) When Vcc =5V, VIHE=2V, VOHM=2.4V, IOHM=2mA, from the equation , VIHE IOHM IOHM Low input Figure 44. CS Pull Down Resistance Rcs 2.4 2x10-3 Rcs 1.2 [k] With the value of Rpd to satisfy the above equation, VOHM becomes 2.4V or higher, and VIHE (=2.0V), the equation is also satisfied. VIHE VOHM IOHM : EEPROM VIH specifications : Microcontroller VOH specifications : Microcontroller IOH specifications (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.

VOHE IOHE VIHM : EEPROM VOH specifications : EEPROM IOH specifications : Microcontroller VIH specifications (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. DO STATUS 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 STATUS *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.

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. Microcontroller EEPROM DI/O PORT DI R DO Figure 49.

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.

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. Start bit CS Because DI=high, set SK=low at CS rise.

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.

Power-Up/Down Conditions (1) At power 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. VCC VCC GND VCC CS GND Bad example Good example Figure 59. Timing at Power ON/OFF Bad exampleCS pin is pulled up to VCC Good exampleIt is low at power ON/OFF. When IC is turned ON while CS is high, EEPROM malfunction write error may occur due to noise and the likes. It's also possible to happen even when CS input is High-Z. Set 10ms or higher to recharge at power OFF. When power is turned on without observing this condition, IC internal circuit may not be reset, which please note. (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.

Noise Countermeasures (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 (0.1F) 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. www.rohm.com (c) 2013 ROHM Co., Ltd. All rights reserved.

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. www.rohm.com (c) 2013 ROHM Co., Ltd. All rights reserved.
