The ATMEGA88PA-MU from Microchip Technology is a low-power 8-bit AVR RISC microcontroller featuring picoPower technology for ultra-low energy consumption in battery-powered applications. The device provides 8 KB Flash, 1 KB SRAM, and 512 bytes EEPROM in a compact 5 x 5 mm QFN-32 package. The 10-bit ADC with 6 channels and 6 PWM channels cover a wide range of analog sensing and control needs. One USART, SPI, and I2C interface enable flexible serial communication. The picoPower technology achieves 0.1 uA in power-down mode and 0.35 uA in power-save mode with RTC running, maximizing battery life.
The ATMEGA88PA-MU uses the AVR enhanced RISC architecture with 131 instructions, most executing in a single clock cycle. The 32 x 8 general-purpose working registers are directly connected to the ALU, allowing two registers to be accessed in one instruction and the result written back in a single clock. The picoPower technology reduces power consumption through multiple techniques: clock gating turns off clocks to unused peripherals, the brown-out detector can be disabled in sleep modes, and the ADC can operate with reduced bandwidth in noise reduction mode. The Flash memory supports in-system programming (ISP) via SPI, and the EEPROM provides non-volatile storage for calibration data and settings. The 10-bit SAR ADC uses a sample-and-hold circuit with selectable reference (AVCC, internal 1.1V, or external AREF).
