The high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
These ICs do NOT come with a pre-loaded bootloader and must be programmed first before using them. The instructions on how to do this can be found at http://arduino.cc/en/Hacking/Bootloader or we can do it for you for an additional fee. We program them for use with a 16Mhz crystal. You will still need to upload your sketch(es) yourself, but it will function as a stand-alone unit once the bootloader has been added.
