ATmega

Several of Atmel's ATmega flash microcontrollers are suitable for connection to an MMC/SD card for PC-compatible data storage. All these devices for use with THIN support SPI. This makes the interface to an SD/MMC card simple and efficient. In addition to the SPI port pins, two GPIOs from the ATmega may be used for Card Detect and Write Protect if required.

The following devices with 4-8KB of RAM are recommended for use with THIN:

The following devices with 2KB of RAM may be used with THIN:

Note: These 2KB RAM devices can be used only with a minimal build of THIN. Using THIN with these devices leaves only about 200 bytes of memory for the user application.

HCC-Embedded has developed and tested sample drivers for use on ATmega devices.
