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: EF for the Flash memory and E1P and

E2P for 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 in the Flash memory and the PSRAM which

would result in a data bus contention. Therefore it

is recommended to put the other device in the high

impedance state when reading the selected de-

vice.
