The high-performance Microchip picoPower® 8-bit AVR® RISC-based microcontroller combines 8 KB ISP Flash memory, 512B EEPROM, 512B SRAM, 12 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with two PWM channels, two 16-bit timer/counters with two PWM channels, internal and external interrupts, a 12-channel 10-bit A/D converter, two On-chip analog comparators, two full-duplex USARTs with Start Frame wake-up from power-down, host/client SPI serial interface, client I2C serial interface, programmable gain stage (1x, 20x, and 100x) for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internally calibrated oscillator, and four software selectable power saving modes. The device operates between 1.7-5.5 volts.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
