IDT70V24S/L

HIGH-SPEED 3.3V 4K x 16 DUAL-PORT STATIC RAM

COMMERCIAL TEMPERATURE RANGE

Dual-Port RAM for 32-bit-or-more word systems. Using the

IDT MASTER/SLAVE Dual-Port RAM 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, 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 technol-

ogy, these devices typically operate on only 350mW of power.

The IDT70V24 is packaged in a ceramic 84-pin PGA, an

84-Pin PLCC, and a 100-pin Thin Quad Plastic Flatpack.

NOTES:

1. All Vcc pins must be connected to the power supply.

2. All GND pins must be connected to the ground supply.

3. This text does not indicate the actual part marking.
