The Processor board is marked 'Reciva' and 'IRM2' in the silk screen, and contains (mainly) three devices, all manufactured by Samsung.
The right image shows a board outline with pin numbers on the pads. These numbers are by no means official, but until we know the exact purpose of the pins, it's handy to give them a number so everybody is talking about the same thing.
Main CPU
- The central one is the main processor, Samsung S3C241 for which a complete datasheet is available
The CPU has the following on-board functions:
- ARM core
- PCM Sound device
- USB host/device interface
- TFT LCD/STN LCD Controller (16bit, 640x480 maximum)
- ...
Smally Tiny12 CPU
There's also an Atmel Tiny12L MCU onboard. No idea what it's doing yet.
Flash
- The top left device is 16Mb*8 flash memory
RAM
- the bottom left device is SDRAM 16M*8
