• Manufacturer: STMicroelectronics

M36W832TE, M36W832BE
SUMMARY DESCRIPTION
The M36W832TE is a low voltage Multiple Memo-
ry Product which combines two memory devices;
a 32 Mbit boot block 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 LFBGA66
(12x8mm, 0.8 mm pitch) package and is supplied
with all the bits erased (set to ‘1’).
