Overview

The ATTINY88-MU is a high-performance, low-power 8-bit AVR microcontroller featuring 8KB of Flash and 28 I/O lines in a compact 32-VQFN package. Operating at up to 12MHz, it provides a balance of peripheral integration including a 10-bit ADC, SPI, and I2C (TWI) for space-constrained embedded designs.

Why Choose This Part

The ATTINY88-MU offers a high pin-to-size ratio with 28 I/O pins in a 32-pin QFN package. Its advanced RISC architecture executes most instructions in a single clock cycle, enabling efficient processing at 12MHz while maintaining low power consumption in idle and power-down modes.

Applications

System Supervisory Circuits
Utilizing the integrated Brown-out Detect, Power-on Reset, and Watchdog Timer for monitoring system health.
Sensor Interface Nodes
Interfacing with analog sensors via the 10-bit ADC and communicating data over I2C or SPI.
I/O Expansion
Providing 28 general-purpose I/O lines to larger systems while maintaining a small 5x5mm PCB footprint.
Portable Battery-Powered Devices
Leveraging power-down modes with ultra-low current consumption and wide operating voltage.

Getting Started

Develop firmware using Microchip Studio or the AVR-GCC toolchain. Hardware programming can be performed via the SPI interface using an AVR ISP mkII or a similar In-System Programmer. For rapid prototyping, consider the ATTINY88-MMH or compatible breakout boards supported by the Arduino IDE via third-party cores like ATTinyCore.
