DESCRIPTION:

The IDT70825 is a high-speed 8K x 16-bit Sequential

Access Random Access Memory (SARAM). The SARAM

offers a single-chip solution to buffer data sequentially on one

port, and be accessed randomly (asynchronously) through

the other port. The device has a Dual-Port RAM based

architecture with a standard SRAM interface for the random

(asynchronous) access port, and a clocked interface with

counter sequencing for the sequential (synchronous) access

port.

Fabricated using CMOS high-performance technology,

this memory device typically operates on less than 900mW of

power at maximum high-speed clock-to-data and Random

Access. An automatic power down feature, controlled by

permits the on-chip circuitry of each port to enter a very low

standby power mode.

The IDT70825 is packaged in a 80-pin Thin Plastic Quad

Flatpack (TQFP) or 84-pin Ceramic Pin Grid Array (PGA).

Military grade product is manufactured in compliance with the

latest revision of MIL-STD-883, Class B, making it ideally

suited to military temperature applications demanding the

highest level of performance and reliability.
