• Manufacturer Part Number: M36DR432A100ZA6C
• Description: 32 Mbit 2Mb x16, Dual Bank, Page Flash Memory and 4 Mbit 256K x16 SRAM, Multiple Memory Product
• Manufacturer: STMICROELECTRONICS [STMicroelectronics]

M36DR432A, M36DR432B
DESCRIPTION
The M36DR432 is a multichip memory device con-
taining a 32 Mbit boot block Flash memory and a
4 Mbit of SRAM. The device is offered in a Stacked
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
grounded.
