• Manufacturer Part Number: m36llr8760d1
• Description: 256 + 128 Mbit Multiple Bank, Multi-level, Burst Flash Memory 64 Mbit Burst Psram, 1.8v Supply, Multi-chip Package
• Manufacturer: STMicroelectronics

FUNCTIONAL DESCRIPTION
The PSRAM and Flash memory components have
separate power supplies but share the same
grounds. They are distinguished by three Chip En-
able inputs: E
respectively, and E
Recommended operating conditions do not allow
more than one device to be active at a time. The

most common example is simultaneous read oper-
ations on one of the Flash memories and the
PSRAM which would result in a data bus conten-
tion. Therefore it is recommended to put the other
devices in the high impedance state when reading
the selected device.
