M36W0R5020T0, M36W0R5020B0
SUMMARY DESCRIPTION
The M36W0R5020T0 and M36W0R5020B0 com-
bine two memory devices in a Multi-Chip Package:
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
(8 x 10mm, 8x10 ball array, 0.8mm pitch) pack-
age.
In addition to the standard version, the package is
also available in Lead-free version, in compliance
with JEDEC Std J-STD-020B, the ST ECOPACK
7191395 Specification, and the RoHS (Restriction
of Hazardous Substances) directive. All packages
are compliant with Lead-free soldering processes.
The memory supplied with all the bits erased (set
to ‘1’).
