0V • • • • • 8-bit Microcontroller with 2K Bytes of In-System Programmable Flash ATtiny22L Preliminary DataShee • • • Description The ATtiny22L is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture.
By executing powerful instructions in a single clock cycle, the ATtiny22L achieves throughputs approaching 1 MIPS 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), Pin Configuration PDIP/SOIC RESET PB3 PB4 GND 1 2 3 4 8 7 6 5 VCC PB2 (SCK/T0) PB1 (MISO/INT0) PB0 (MOSI) Rev.
