M36W432 Datasheet - STMicroelectronics

SUMMARY DESCRIPTION
The M36W432 is a low voltage Multiple Memory Product which combines two memory devices; a 32 Mbit boot block Flash memory and a 4 Mbit SRAM. Recommended operating conditions do not allow both the Flash and the SRAM to be active at the same time.
