IDT7016S/L
High-Speed 16K x 9 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7016 is a high-speed 16K x 9 Dual-Port Static RAM. The
IDT7016 is designed to be used as stand-alone Dual-Port RAMs or
as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-
more wider 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 addi-
tional discrete logic.
This device provides two independent ports with separate con-
trol, address, and I/O pins that permit independent, asynchronous
Pin Configurations
(1,2,3)
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 750mW of power.
The IDT7016 is packaged in a ceramic 68-pin PGA, a 64-pin
PLCC and an 80-pinTQFP (Thin Quad Flatpack). Military grade
product is manufactured in compliance with the latest revision of
MIL-PRF-38535 QML, making it ideally suited to military tempera-
ture applications demanding the highest level of performance and
reliability.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above
those indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect reliability.
