Overview

The ATTINY88-AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 8KB of flash memory and 28 I/O lines in a compact 32-TQFP package. It operates at speeds up to 12MHz and is designed for applications requiring a high pin count in a small footprint without the overhead of a full ATmega controller.

Why Choose This Part

This MCU provides an exceptional ratio of I/O pins to flash memory, making it ideal for simple logic tasks that require many connections. Its wide operating voltage range from 1.8V to 5.5V allows it to integrate easily into both low-voltage mobile and standard 5V industrial systems.

Applications

I/O Expansion
Utilizing 28 GPIO pins to manage multiple digital inputs, switches, and LED indicators in space-constrained designs.
System Monitoring
Using the on-chip temperature sensor and analog-to-digital converter to monitor system health and thermal conditions.
Peripheral Bridging
Acting as an interface bridge between I2C and SPI sensors and a primary application processor.
Battery Powered Devices
Leveraging ultra-low power consumption of 0.24mA at 1MHz and a 0.1uA power-down mode for long-term battery operation.
