GENERAL DESCRIPTION
The
FT5C4008
is a 4 megabit monolithic CMOS SRAM,
organised as a 512K x 8.
The evolutionary 32 pin device allows for easy upgrades from
the 1
Meg
SRAM.
For flexibility in high-speed memory applications,
FT
offers
chip enable (CE\) and output enable (OE\) capabilities. These
enhancements can place the outputs in High-Z for additional flexibil-
ity in system design.
Writing to these devices is accomplished when write enable (WE\)
and CE\ inputs are both LOW. Reading is accomplished when WE\
remains HIGH and CE\ and OE\ go LOW. This allows systems
designers to meet low standby power requirements.
All devices operate from a single +5V power supply and all
inputs are fully TTL-Compatible.
