Overview The ATtiny2313 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny2313 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con- sumption versus processing speed. 2 ATtiny2313 2543MAVR10/16 (T0) PD4 6 20 PD0 (RXD) (OC0B/T1) PD5 7 19 PA2 (RESET/dW) GND 8 18 VCC (ICP) PD6 9 17 PB7 (UCSK/SCK/PCINT7) (AIN0/PCINT0) PB0 10 16 PB6 (MISO/DO/PCINT6)
