The ATTINY84-20PU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 512B EEPROM, 12 general purpose I/O lines, 32 general purpose working registers, an 2 timers/counters (8-bit/16-bit) with two PWM channels each, internal and external interrupts, 8-channel 10-bit A/D converter, programmable gain stage (1x, 20x) for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internal calibrated oscillator and four software selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed.
