ATMEGA88PA-PU 8-bit Microcontrollers
The ATMEGA88PA-PU is a 8-bit low-power CMOS Microcontroller Unit based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega48PA/88PA/168PA/328P achieves throughputs approaching 1MIPS per MHz allowing the system designed to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 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 more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

Comparison Between Processors
- The Atmel ATmega48PA/88PA/168PA differ only in memory sizes, boot loader support, and interrupt vector sizes.
- The Atmel ATmega48PA/88PA/168PA support a real read-while-write self-programming mechanism. There is a separate
boot loader section, and the SPM instruction can only execute from there. In the Atmel ATmega48PA there is no read-While write support and no separate boot loader section. The SPM instruction can execute from the entire flash.
