IDT7134SA/LA

Description

The IDT7134 is a high-speed 4K x 8 Dual-Port Static RAM

designed to be used in systems where on-chip hardware port arbitration

is not needed. This part lends itself to those systems which cannot

tolerate wait states or are designed to be able to externally arbitrate or

withstand contention when both sides simultaneously access the

same Dual-Port RAM location.

The IDT7134 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. It is the users responsibility

to ensure data integrity when simultaneously accessing the same

memory location from both ports. 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 IDTs CMOS high-performance technology, these

Dual-Port typically operate on only 700mW of power. Low-power (LA)

versions offer battery backup data retention capability, with each port

typically consuming 200µW from a 2V battery.

The IDT7134 is packaged on either a sidebraze or plastic 48-pin

DIP, 48-pin LCC, 52-pin PLCC and 48-pin Flatpack. Military grade

product is manufactured in compliance with the latest revision of MIL-

PRF-38535 QML, making it ideally suited to military temperature

applications demanding the highest level of performance and reliability.
