IDT7015S/L
HIGH-SPEED 8K x 9 DUAL-PORT STATIC RAM
MILITARY AND COMMERCIAL TEMPERATURE RANGES
MASTER/SLAVE Dual-Port RAM approach in 18-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.
The IDT7015 is packaged in a ceramic 68-pin PGA, a 64-
pin PLCC and an 80-pin TQFP (Thin Quad FlatPack). 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.
