8-bit ATtiny AVR-RISC microcontroller, 2 KB, 20 MHz, WQFN-20

ATTINY2313A, MCU, 8BIT, 20MHZ,
Description:
The high-performance Microchip picoPower AVR RISC-based CMOS 8-bit microcontroller combines 2KB flash memory, 128B EEPROM, 128B SRAM, 18 multi-purpose I/O lines, 32 multi-purpose work registers, A single-wire interface for on-chip debugging, two flexible timers/counters with comparison modes, internal and external interrupts, serial programmable USART, a universal serial interface (USI) with start condition detector, programmable watchdog timer with internal oscillator, and three software-selectable power save modes. The device operates between 1.8 and 5.5 volts.
By executing powerful commands in a single clock cycle, the device achieves throughputs of nearly 1 MIPS per MHz, balancing power consumption and processing speed.
