IDT7015S/L
High-Speed 8K x 9 Dual-Port Static RAM Industrial and Commercial Temperature Ranges

Description:
The IDT7015 is a high-speed 8K x 9 Dual-Port Static RAM. The
IDT7015 is designed to be used as a stand-alone Dual-Port RAM or as
a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more word
systems. Using the IDT 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

NOTES:
1. All VCC pins must be connected to power supply.
2. All GND pins must be connected to ground supply.
3. Package body is approximately .95 in x .95 in x .17 in.
4. This package code is used to reference the package diagram.
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 CMOS high-performance technology, these de-
vices typically operate on only 750mW of power.
The IDT7015 is packaged in a 64-pin PLCC and an 80-pinTQFP
(Thin Quad Flatpack).
