ATTINY2313-20SUR Datasheet PDF - Microchip

●The ATTINY2313-20SUR is a low-power 8-bit CMOS Microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny2313 achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny2313 provides 2kB of in-system programmable flash, 128byte EEPROM and 128byte SRAM. The device supports a throughput of 20MIPS at 20MHz.
