Functional description
The PSRAM and Flash memory components have separate power supplies but share the
same grounds. They are distinguished by two Chip Enable inputs: E
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 operations on one of the Flash
memory and the PSRAM components 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.
