ATtiny84 AVR 14 Pin 20MHz 8K 12A/D - DIP14

ATtiny84 AVR 14 Pin 20MHz 8K 12A/D - DIP14

The ATtiny84 is another of Atmel’s little tiny 8-Bit Processors. 8K ISP flash memory for program storage, 12 general-purpose I/O lines, and an 8-channel 10 bit ADC.

It will run up to 20MHz with an external crystal and can be programmed in circuit.

The device has a programmable watchdog timer with an internal oscillator, an internal calibrated oscillator, and four software selectable power saving modes.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed.

The device operates between 1.8-5.5 volts.
