Description
The IDT7007 is a high-speed 32K x 8 Dual-Port Static RAM. The
IDT7007 is designed to be used as a stand-alone 256K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-
more word systems. Using the IDT MASTER/SLAVE Dual-Port
RAM approach in 16-bit or wider memory system applications
results in full-speed, error-free operation without the need for addi-
tional discrete logic.
This device provides two independent ports with separate con-
trol, 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 technology,
these devices typically operate on only 850mW of power.
The IDT7007 is packaged in a 68-pin pin PGA, a 68-pin PLCC,
and an 80-pin thin quad flatpack, TQFP. Military grade product is
manufactured in compliance with the latest revision of MIL-PRF-38535
QML, Class B, making it ideally suited to military temperature applications
demanding the highest level of performance and reliability.
