• Manufacturer Part Number: M36L0R8060
• Description: 256 Mbit (Multiple Bank / Multi-Level / Burst) Flash Memory 64 Mbit (Burst) PSRAM
• Manufacturer: ST Microelectronics

M36L0R8060T0, M36L0R8060B0
FUNCTIONAL DESCRIPTION
The PSRAM and Flash memory components have
separate power supplies but share the same
grounds. They are distinguished by two Chip En-
able inputs: E
the PSRAM.
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 and the PSRAM which
would result in a data bus contention. Therefore it
is recommended to put the other devices in the
high impedance state when reading the selected
device.
