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
CE
,
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.
