Description

The IDT70V24 is a high-speed 4K x 16 Dual-Port Static RAM. The

IDT70V24isdesignedtobeusedasastand-alone64K-bitDual-PortRAM

or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more

wordsystems.UsingtheIDTMASTER/SLAVEDual-PortRAMapproach

in 32-bit or wider memory system applications results in full-speed, error-

free operation without the need for additional discrete logic.

reads or writes to any location in memory. An automatic power down

feature controlled by

a very low standby power mode.

Fabricated using IDT’s CMOS high-performance technology,

these devices typically operate on only 400mW of power.

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

PLCC and a 100-pin Thin Quad Flatpack.

NOTES:

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

3. J84-1 package body is approximately 1.15 in x 1.15 in x .17 in.

PN100-1 package body is approximately 14mm x 14mm x 1.4mm.
