Overview

The ATTINY85-20MU is a high-performance, low-power 8-bit AVR RISC-based microcontroller. It packs 8KB of ISP flash memory, 512B EEPROM, and 512B SRAM into a compact 20-pad QFN package, making it ideal for space-constrained embedded designs.

Why Choose This Part

The device achieves throughputs approaching 1 MIPS per MHz, allowing for optimized power consumption versus processing speed. Its small pin count and dedicated internal oscillator reduce total system bill-of-materials and PCB complexity.

Applications

Portable Consumer Electronics
Low power consumption and small physical footprint make it suitable for battery-operated handheld devices.
Sensor Interface
Utilizes the integrated 10-bit ADC for monitoring analog sensors in distributed industrial environments.
Signal Conditioning
Ideal for simple glue logic replacements or pulse-width modulation tasks in power management systems.

Getting Started

Engineers can develop for this part using the Microchip Studio IDE or the open-source AVR-GCC toolchain. Common hardware tools include the AVR ISP mkII or the MPLAB PICkit 4 for programming and debugging.
