SUMMARY DESCRIPTION
The M68AF127B is a 1Mbit (1,048,576 bit) CMOS
SRAM, organized as 131,072 words by 8 bits. The
device features fully static operation requiring no
external clocks or timing strobes, with equal ad-
dress access 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 M68AF127B is available in SO32, PDIP32,
TSOP32 (8x13.4mm) and TSOP32 (8x20mm)
packages.
