Overview

The ATTINY88-AUR is a low-power 8-bit AVR microcontroller featuring 8KB of Flash memory and 28 general-purpose I/O lines in a compact 32-TQFP package. It operates at speeds up to 12MHz and is designed for applications requiring high I/O counts with a small silicon footprint. The device includes essential peripherals such as a 10-bit ADC, SPI, and an I2C-compatible 2-wire serial interface.

Why Choose This Part

This MCU offers an excellent ratio of I/O pins to package size, providing 28 GPIOs in a 7x7mm TQFP. Its 123 instructions, most of which execute in a single clock cycle, allow for efficient processing despite the modest 12MHz clock speed. The inclusion of 64 bytes of EEPROM provides reliable non-volatile storage for calibration data and user settings.

Applications

I/O Expansion
Utilizing 28 I/O pins to manage user interfaces, status LEDs, and digital signaling in space-constrained designs.
Sensor Interfacing
Using the integrated 10-bit ADC and I2C/SPI interfaces to aggregate data from multiple analog and digital sensors.
Handheld Peripheral Control
Managing power-up sequences and simple logic for battery-operated consumer electronics thanks to its low-power sleep modes.
