The high performance Microchip 8-bit AVR RISC-based microcontroller unites 32KB ISP flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three adjustable timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire sequential interface, SPI serial port, 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 system operates between 1.8-5.5 volts. By executing powerful instructions in one clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power intake and processing speed.
