CMOS STATIC RAM MODULE
IDT7MB4048
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.
