GENERAL DESCRIPTION

The AS5C4009LL is organized as 524,288 x 8 SRAM utilizing a

special ultra low power design process. ASI’s pinout adheres to the

JEDEC standard for pinout on 4 megabit SRAMs. The evolutionary 32

pin version allows for easy upgrades from the 1 meg SRAM design.

For flexibility in memory applications, ASI offers chip enable (CE\)

and output enable (OE\) capabilities. These features can place the

outputs in High-Z for additional flexibility in system design.

This devices operates from a single +5V power supply and all

inputs and outputs are fully TTL-compatible.

Writing to these devices is accomplished when write enable (WE\)

and CE\ inputs are both LOW. Reading is accomplished when WE\

remains HIGH and CE\ and OE\ go LOW. The device offers a re-

duced power standby mode when disabled, by lowering VCC to 2V and

maintaining CE\ = 2V. This allows system designers to meet ultra low

standby power requirements.
