3.3V CMOS STATIC RAM

4 MEG (1M x 4-BIT)

Integrated Device Technology, Inc.

ADVANCE

INFORMATION

IDT71V428

FEATURES:

• 1M x 4 advanced high-speed CMOS Static RAM

• JEDEC Center Power / GND pinout for reduced noise

• Equal access and cycle times

— 12/15/20ns

• Single 3.3V power supply

• One Chip Select plus one Output Enable pin

• Bidirectional data inputs and outputs directly

TTL-compatible

• Low power consumption via chip deselect

• Available in 32-pin, 400 mil plastic SOJ package

DESCRIPTION:

The IDT71V428 is a 4,194,304-bit high-speed Static RAM

organized as 1M x 4. It is fabricated using IDT’s high-

perfomance, high-reliability CMOS technology. This state-of-

the-art technology, combined with innovative circuit design

techniques, provides a cost-effective solution for high-speed

memory needs.

The IDT71V428 has an output enable pin which operates

as fast as 6ns, with address access times as fast as 12ns. All

bidirectional inputs and outputs of the IDT71V428 are TTL-

compatible and operation is from a single 3.3V supply. Fully

static asynchronous circuitry is used, requiring no clocks or

refresh for operation.

The IDT71V428 is packaged in a 32-pin, 400mil Plastic

SOJ.
