Device Overview

Summary

The high-performance Microchip picoPower 8-bit AVR RISC-based
microcontroller combines 64KB ISP flash memory with read-while-write
capabilities, 2KB EEPROM, 4KB SRAM, 32 general purpose I/O lines, 32
general purpose working registers, real time counter, three flexible
timer/counters with compare modes and PWM, 2 USARTs, byte oriented
2-wire serial interface, 8-channel/10-bit A/D converter with optional
differential input stage with programmable gain, programmable watchdog
timer with internal oscillator, SPI serial port, JTAG (IEEE 1149.1
compliant) interface for on-chip debugging and programming, and six
software selectable power saving modes. The device operates between
2.7-5.5 volts. By executing powerful instructions in a single clock
cycle, the device achieves throughputs approaching 1 MIPS per MHz,
balancing power consumption and processor speed

Additional Features
    • Advanced RISC architecture
      • 131 powerful Instructions – most single-clock cycle execution
      • 32 x 8 general purpose working registers
      • Fully static operation
      • Up to 16 MIPS throughput at 16MHz
      • On-chip 2-cycle multiplier
