Architecture
– Ideal For ROM, EEPROM and
Bulk Flash EPROM Integration
For Embedded Application
Intel’s advanced SmartVoltage 2-, 4- and
8-Mbit flash memories offer users optimal
benefits in a mid-density flash. Using a
cost-effective and highly advanced process
technology, the SmartVoltage 2-, 4- and
8-Mbit products offer new capabilities in
establishing a standard in flash memory.
You can choose among read/write volt-
ages, X8 or X8/X16 data bus, hardware
reset, high performance read access, trans-
parent automated erase/program algo-
rithms and absolute write protection.
The SmartVoltage 2-, 4- and 8-Mbit
memory architecture is ideal for integrat-
ing boot ROM, EEPROM-like parameter
storage and bulk flash code storage–with
optimized memory blocks for each need.
Designers can incorporate this tuned
architecture in a selection of footprint
compatible densities, including 2 Mbit,
4 Mbit and 8 Mbit (mid-95).
The industry today demands flash memo-
ry products that have advanced features,
are cost effective, and deliver flexibility
and ease of use. Intel delivers these capa-
bilities in 40-pin and greater TSOP and
PSOP packages. Plus, only Intel offers
voltage options for standard 5V read,
down to 3.3V read for low-power current
and future needs in one product offering
at no price premium. In addition, Intel
offers high-throughput efficiency in man-
ufacturing with 12V programming, and
simplicity of board design with 5V
writes.
Intel’s SmartVoltage 2-, 4- and 8-Mbit
provide high integration for space-
constrained embedded applications, low
voltage for portable applications, and
absolute block locking for easy system
recovery in PC BIOS applications.
