ATMEL ATMEGA88PA-MMH 8-bit Microcontroller, 28QFN

The ATMEL ATMEGA88PA-MMH is a high-performance, 8-bit picoPower AVR RISC-based microcontroller designed for efficiency and versatility. It combines 8 kB of in-system programmable (ISP) flash memory with read-while-write capabilities, 512 B of EEPROM, and 1 kB of SRAM to support a wide range of embedded applications. With 23 general-purpose I/O lines and 32 general-purpose working registers, it offers ample connectivity and processing flexibility.

This device features three flexible timer/counters with compare modes, internal and external interrupts, and a programmable serial USART for robust communication. It also includes a byte-oriented 2-wire serial interface (I2C), an SPI serial port, and a 6-channel, 10-bit A/D converter for precise analogue signal processing. A programmable watchdog timer with an internal oscillator and five software-selectable power-saving modes help optimise energy consumption, which is critical for battery-powered designs.

Operating on a supply voltage from 1.8V to 5.5V, the microcontroller achieves a throughput approaching 1 MIPS per MHz by executing powerful instructions in a single clock cycle, striking an ideal balance between processing speed and power efficiency. Its advanced RISC architecture includes an on-chip 2-cycle multiplier for faster mathematical operations.
