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

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.
