FEATURES:

• High-density 4-megabit (512K x 8) Static RAM module

• Fast access time: 25ns (max.)

Surface mounted plastic packages on a 32-pin, 600 mil

FR-4 DIP substrate

• Single 5V (

±10%) power supply

• Inputs/outputs directly TTL-compatible

DESCRIPTION:

The IDT7MB4048 is a 4-megabit (512K x 8) Static RAM

module constructed on a multilayer epoxy laminate (FR-4)

substrate using four 1 megabit SRAMs and a decoder. The

IDT7MB4048 is available with access times as fast as 25ns.

The IDT7MB4048 is packaged in a 32-pin FR-4 DIP resulting

in the JEDEC footprint in a package 1.6 inches long and 0.6

inches wide.

All inputs and outputs of the IDT7MB4048 are TTL-com-

patible and operate from a single 5V supply. Fully asynchro-

nous circuitry requires no clocks or refresh for operation and

provides equal access and cycle times for ease of use.
