• Manufacturer Part Number: M36L0T7050
• Description: 128Mbit (Multiple Bank / Multi-Level / Burst) Flash Memory 32Mbit (2M x16) PSRAM
• Manufacturer: ST Microelectronics

M36L0T7050T0, M36L0T7050B0
SUMMARY DESCRIPTION
The M36L0T7050T0 and M36L0T7050B0 com-
bine two memory devices in a Multi-Chip Package:
a 128-Mbit, Multiple Bank Flash memory, the
M30L0T7000T0 or M30L0T7000B0, and a 32-Mbit
PseudoSRAM, the M69AW048B. 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 compli-
ance 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 solder-
ing processes.
The memory is supplied with all the bits erased
(set to ‘1’).
