SUMMARY DESCRIPTION
The M76DW52003TA and M76DW52003BA are
low voltage Multiple Memory Products that com-
bine two memory devices; a 32 Mbit Dual Bank,
boot block Flash memory (M29DW323D(T/B)) and
a 4Mbit SRAM. This document should be read in
conjunction with the M29DW323D datasheet.
Recommended operating conditions do not allow
both the Flash and SRAM devices to be active at
the same time.
The
memory
is
offered
in
an
LFBGA73
(8 x 11.6mm, 0.8 mm pitch) package and is sup-
plied with all the bits erased (set to ‘1’).
