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

The ATtiny84 is an 8-bit AVR microcontroller in a 14-pin DIP package. With 8KB of flash, 512 bytes of SRAM, 512 bytes of EEPROM, and an 8-channel 10-bit ADC, it offers substantial capability in a compact form factor. Runs at up to 20MHz with an external crystal and supports in-circuit programming via ISP.
