Hardware Matrix
The radios contain slightly different internal hardware architectures, including different LCDs, Keypads and some different pin connections on the Barracuda module. A Hardware Matrix showing the differences, plus datasheets for the hardware has been compiled.
Barracuda hardware
The Barracuda module is a pretty straightforward, but very compact, board with CPU, flash, ram and some interfacing for audio, buttons and LCD display
The Processor board is marked 'Reciva' and 'IRM2' in the silk screen, and contains (mainly) three devices, all manufactured by Samsung.
The next row of images 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.
Diagnostics
Diagnostic Captures have been taken to diagnose:
Main CPU
- The central one is the main processor,
Samsung S3C2410 for which a complete datasheet is available
The processor is running at 202.80MHz (MPLLCON=000a1031)
The CPU has the following on-board functions:
- ARM920T core
- PCM Sound device
- USB host/device interface
- TFT LCD/STN LCD Controller (16bit, 640x480 maximum)
- JTAG Port (is TRST Open Drain or Push Pull?)
- ...
Smally Tiny12 CPU
There's also an Atmel Tiny12L MCU onboard. No idea what it's doing yet.
Flash
- The top left device is the Reciva NAND Flash, which a K9F2808U0C: 16Mb*8 flash memory.
RAM
- the bottom left device is SDRAM 16M*16 (K4S561632E-TC75)
Schematic
This schematic (work in progress) is an amalgumation of information extracted from several disassembled radios, plus information extracted from the GPL'd source.
Source Data
Source files (schematic, drawings, etc...) can be found on the Source Files page.
