IDT7025S/L
HIGH-SPEED 8K x 16 DUAL-PORT STATIC RAM
MILITARY AND COMMERCIAL TEMPERATURE RANGES
DESCRIPTION:
The IDT7025 is a high-speed 8K x 16 Dual-Port Static
RAM. The IDT7025 is designed to be used as a stand-alone
128K-bit Dual-Port RAM or as a combination MASTER/
SLAVE Dual-Port RAM for 32-bit or more word systems.
Using the IDT MASTER/SLAVE Dual-Port RAM approach in
32-bit or wider memory system applications results in full-
speed, error-free operation without the need for additional
discrete logic.
This device provides two independent ports with separate
control, address, and I/O pins that permit independent,
asynchronous access for reads or writes to any location in
memory. An automatic power down feature controlled by Chip
Enable (
CE
) permits the on-chip circuitry of each port to enter
a very low standby power mode.
Fabricated using IDT’s CMOS high-performance technol-
ogy, these devices typically operate on only 750mW of power.
Low-power (L) versions offer battery backup data retention
capability with typical power consumption of 500
μ
W from a 2V
battery.
The IDT7025 is packaged in a ceramic 84-pin PGA, an 84-
pin quad flatpack, an 84-pin PLCC, and a 100-pin TQFP.
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.
