Description :

ATtiny20 is a low-power CMOS 8-bit microcontroller based on the compact AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny20 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 16 general purpose working registers and system registers. All 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 compact and code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.



1. 2K bytes of in-system programmable Flash
2. 128 bytes of SRAM
3. Twelve general purpose I/O lines
4. 16 general purpose working registers
5. An 8-bit Timer/Counter with two PWM channels
6. A 16-bit Timer/Counter with two PWM channels
7. Internal and external interrupts
8. An eight-channel, 10-bit ADC
9. A programmable Watchdog Timer with internal oscillator
10. A slave two-wire interface
11. A master/slave serial peripheral interface
12. An internal calibrated oscillator
13. Four software selectable power saving modes
