SUMMARY DESCRIPTION
The M68AF031A is a 256 Kbit (262,144 bit) CMOS
SRAM, organized as 32,768 bytes. The device
features fully static operation requiring no external
clocks or timing strobes, with equal address ac-
cess and cycle times. It requires a single 4.5 to
5.5V supply. This device has an automatic power-
down feature, reducing the power consumption by
over 99% when deselected.
The M68AF031A is available in SO28 (28-lead
Small Outline), PDIP28 (28-pin Plastic Dual-In-
Line) and TSOP28 (28-lead Thin Small Outline,
Standard and Reverse Pinout) packages.
In addition to the standard version, the TSOP28
Standard package is also available in Lead-free
version (standard and Tape & Reel packing), in
compliance with JEDEC Std J-STD-020B, the ST
ECOPACK 7191395 Specification, and the RoHS
(Restriction of Hazardous Substances) directive. It
is also compliant with Lead-free soldering pro-
cesses.
