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 address 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.
