The high-performance, low-power Microchip 8-bit AVR® RISC-based
microcontroller combines 16 KB ISP flash memory with
read-while-write capabilities, 512B EEPROM, 512B SRAM, 22 general
purpose I/O lines, 32 general purpose working registers, two
flexible timer/counters with compare modes and PWM, USART,
programmable watchdog timer with internal oscillator, SPI serial
port,
debugWIRE interface for on-chip debugging and programming, and five
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 one MIPS per
MHz, balancing power consumption and processing speed.
