The AVR core combines a rich instruction set with 32 general purpose working registers. It features 4Kbytes of in-system programmable flash with read-while-write capabilities, 256bytes EEPROM, 512 bytes SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire serial interface, an SPI serial port, a 8-channel 10-bit ADC, a programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The idle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire serial interface, SPI port, and interrupt system to continue functioning. The power-down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.Up to 16MIPS throughput at 16MHz On-chip 2-cycle multiplier Programming lock for software security Two 8-bit Timer/Counters with separate prescaler and compare mode One 16-bit Timer/Counter with separate prescaler, compare mode, and capture mode Real time counter with separate oscillator Master/slave SPI serial interface Byte-oriented 2-wire serial interface Programmable watchdog timer with separate on-chip oscillator On-chip analog comparator Interrupt and wake-up on pin change Power-on reset and programmable brown-out detection Internal calibrated oscillator External and internal interrupt sources 32-lead TQFP package
