SUMMARY DESCRIPTION

The M36W0R6040T0 and M36W0R6040B0 are Multiple Memory Products which combine two memory devices; a 64-Mbit, Multiple Bank Flash memories, the M58WR064FT/B, and a 16-Mbit Pseudo SRAM, the M69AR024B. Recommended operating conditions do not allow more than one memory to be active at the same time. The memory is offered in a Stacked TFBGA88 (8x10mm, 8x10 ball array, 0.8mm pitch) package.

In addition to the standard version, the packages are also available in Lead-free version, in compliance with JEDEC Std J-STD-020B, the ST ECO PACK 7191395 Specification, and the RoHS (Restriction of Hazardous Substances) directive.

All packages are compliant with Lead-free soldering processes.
