Emma Mobile1


Overview

This is the page for the Emma Mobile1 SoC, also known as em1 or mp200, from NEC/Renesas. There is a linux port for it, released by Sony for it's NWZ players (see sony open source content for the sony nwz-e463 for example).

Datasheet

The datasheets are availble on Renesas websites using the internal search engine but are very hard to find. They are also attached to this page. A special comment about missings documents:
  • The NAND flash module datasheet is impossible to find
  • Two modules (MMM and MSP) which are crypto related probably never were documented and linux has no code for it.

Undocumented modules

MMM

The MMM crypto modules is located in Bank 6 at address 0x60040000.

Features

This modules seems to supports DES and AES in CBC and ECB modes. This list is by no way exhaustive.
