DESCRIPTION:

The IDT71T024 is a 1,048,576-bit very low-power Static

RAM organized as 128K x 8. It is fabricated using IDT’s high-

reliability CMOS technology. This state-of-the-art technology,

combined with innovative circuit design techniques, provides

a cost-effective solution for low-power memory needs. It uses

a 6-transistor memory cell.

Operation is from a single extended-range 2.5V supply.

This extended supply range makes the device ideally suited

for unregulated battery-powered applications. Fully static

asynchronous circuitry is used, requiring no clocks or refresh

for operation.

The IDT71T024 is packaged in a JEDEC standard 32-pin

TSOP Type I.
