This is Atmel's high performance, low power 8-bit AVR ATMega328 microcontroller in a pint-sized TQFP package. Yes, you really can solder that. Note: There is no difference between this part and its previous version. This new copy was created to help make our in house assemblies easier to produce and manage. Features: 1.8-5.5V operating range
Up to 20MHz
32kB Flash program memory
2kB Internal SRAM
2 8-bit Timer/Counters
1 16-bit Timer/Counter
RTC with separate...
The ATtiny84 is another of Atmel's little tiny 8-Bit Processors. 8K of program space, 12 I/O lines, and 8-channel 10 bit ADC. It will run up to 20MHz with an external crystal and can be programmed in circuit. Documents: Datasheet
