ATTINY84-20SSU

ATMEL  ATTINY84-20SSU  微控制器, 8位, 低功率高性能, ATtiny, 20 MHz, 8 KB, 512 Byte, 14 引脚, SOIC

The is a 8-bit high-performance low-power AVR RISC-based Microcontroller combines 8kB ISP flash memory, 512B EEPROM, 512B SRAM, 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.
