The Microchip ATTINY167-MMU is a compact 8-bit AVR microcontroller with 16KB flash and 512 bytes of RAM. It operates from 1.8V to 5.5V and runs at up to 20MHz, offering flexible power options. Integrated peripherals include PWM, temperature sensor, and brown-out detection. The 20-WFQFN package is ideal for space-constrained designs requiring robust performance.
- Wide Voltage Range (1.8V-5.5V): Simplifies design across mixed-voltage systems.
- High Speed at Low Voltage: 20MHz at 1.8V enables fast processing in battery devices.
- Integrated Temperature Sensor: Eliminates external components for thermal monitoring.
- Compact QFN Package: Saves board space for miniaturized products.
Battery-Powered Remote Controls
With 1.8V operation and WDT, it maintains low standby current for years of use in consumer remotes.
LED Lighting Controllers
PWM channels and 20MHz speed enable smooth dimming and color mixing in smart bulbs.
Automotive Sensor Interfaces
Operating from -40°C to 85°C, it reads temperature and pressure sensors in engine bay modules.
Portable Health Monitors
The small QFN package and low power make it suitable for wearable heart-rate or activity trackers.
Small Appliance Control
Replaces discrete logic in coffee makers or air purifiers with reliable timer and PWM functions.
Security Keypads
512 bytes of RAM and 16KB flash handle debouncing and encryption for access control panels.
