STM32

Since I wanted to todo something with new CortexM3 core from ARM, My experience is that for software development is very nice I was looking for a cpu with external memory interface. The only one which can satisfy this is the STM32. Luminary has announced a chip with external interface but it is still not available. So I did a CortexM3 evaluation board for the STM32.

The features are:

- STM32F103 (144pin QFP package), 512k flash, 64k internal SRAM
- 2x 512k x 16 bit external SRAM
- Dataflash
- FRAM
- DM9000A 10/100 Mbit Ethernet
- High speed CAN
- RS485
- IRDA
- JTAG + trace connector (4 bit ETM)
- I2C
- USB
- UART (with or without HW handshake)
- some switches
- some LEDs
- expansion header for SPI devices, e.g. displays or rf modules

You find the schematic in the download area.
