M36W832BE Datasheet - STMicroelectronics

SUMMARY DESCRIPTION
The M36W832TE is a low voltage Multiple Memory 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 active at the same time.
