M36WT864

64 Mbit (4Mb x16, Multiple Bank, Burst) Flash Memory and 8 Mbit (512K x16) SRAM, Multiple Memory Product

STMicroelectronics 

M36WT864TF, M36WT864BF

SUMMARY DESCRIPTION

The M36WT864 is a low voltage Multiple Memory

Product which combines two memory devices; a

64 Mbit Multiple Bank Flash memory and an 8 Mbit

SRAM. Recommended operating conditions do

not allow both the Flash and the SRAM to be ac-

tive at the same time.

The memory is offered in a Stacked LFBGA96 (8

x 14mm, 0.8 mm pitch) package and is supplied

with all the bits erased (set to ‘1’).
