描述 Description

The M36P0R8070E0 combines two memories in a multichip package:

● 256-Mbit multiple bank Flash memory (the M58PR256J)

● 128-Mbit PSRAM (the M69KB128AA).

This datasheet should be read in conjunction with the M58PR256J and M69KB128AA datasheets, which are available from your local Numonyx distributor.

Recommended operating conditions do not allow more than one memory to be active at the same time.

The memory is offered in a stacked TFBGA107 package, and it is supplied with all the bits erased (set to ‘1’).
