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.

Summary Datasheet:

Complete Datasheet:


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 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.
