DESCRIPTION
The M36DR232 is a multichip memory device con-
taining a 32 Mbit boot block Flash memory and a
4Mbit of SRAM. Thedeviceis offered in aStacked
LFBGA66 (0.8 mm pitch) package.
The two components are distinguished by use with
three chip enable inputs: EF for the Flash memory
and, E1S and E2S for the SRAM. The two compo-
nents are also separately power supplied and
