HIGH-SPEED 8K x 8 DUAL-PORT STATIC RAM
MILITARY AND COMMERCIAL TEMPERATURE RANGES
RAM for 16-bit-or-more word systems. Using the IDT MAS-
TER/SLAVE Dual-Port RAM approach in 16-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
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
W from a 2V
battery.
The IDT7005 is packaged in a ceramic 68-pin PGA, a 68-
pin quad flatpack, a 68-pin PLCC and a 64-pin Thin Plastic
Quad Flatpack (TQFP). Military grade product is manufac-
tured 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.
