128K Bytes self-programming Flash Program Memory, 16K Bytes SRAM, 4K Bytes EEPROM, two 16-bit Timer/Counters, two 8-bit Timer/Counters, Real Time Counter, 8 Channel 10-bit A/D-converter(TQFP/MLF). JTAG Interface for On-chip Debug. Up to 20 MIPS throughput at 20 MHz. The ATmega1284P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced
RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega1284P
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
