M36W0T705

Summary description

The M36P0R9070E0 combines two memory devices in one Multi-Chip Package:
● 512-Mbit Multiple Bank Flash memory (the M58PR512J).
● 128 Mbit PSRAM (the M69KB128AB).
The purpose of this document is to describe how the two memory components operate with respect to each other. It should be read in conjunction with the M58PRxxxJ and M69KB128AB datasheets, where all specifications required to operate the Flash memory and PSRAM components are fully detailed. The M58PR512J and M69KB128AB datasheets are available from www.numonyx.com .
