IDT70P258/248L
Low Power 1.8V 8K/4K x 16 Dual-Port Static RAM
Description
The IDT70P258/248 is a very low power 8K/4K x 16 Dual-Port
Static RAM. The IDT70P258/248 is designed to be used as a stand-alone
128/64K-bit Dual-Port SRAM or as a combination MASTER/SLAVE Dual-
Port SRAM for 32-bit-or-more word systems. Using the IDT MASTER/
SLAVE Dual-Port SRAM approach in 32-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,
Industrial Temperature Range
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 technology,
these devices typically operate on only 27mW of power.
The IDT70P258/248 is packaged in a 100 ball 0.5mm- pitch Ball
Grid Array. The package is a 1mm thick and designed to fit in wireless
handset applications.
