GENERAL DESCRIPTION

The AS5C512K8 is a high speed SRAM. It offers flexibility in

high-speed memory applications, with chip enable (CE\) and output

enable (OE\) capabilities. These features can place the outputs in

High-Z for additional flexibility in system design.

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.

As a option, the device can be supplied offering a reduced power

standby mode, allowing system designers to meet low standby power

requirements. This device operates from a single +5V power supply

and all inputs and outputs are fully TTL-compatible.

The AS5C512K8DJ offers the convenience and reliability of the

AS5C512K8 SRAM and has the cost advantage of a durable plastic.

The AS5C512K8DJ is footprint compatible with 36 pin CSOJ

package of the SMD 5692-95600.
