The Microchip ATTINY25V-10MFR is an 8-bit AVR MCU with 2KB flash and 128 bytes RAM. It runs at 20MHz from 1.8V to 5.5V, featuring brown-out detection, POR, PWM, and WDT. The 20-WFQFN package is ideal for compact, low-power embedded designs.
- Ultra-Low Voltage Operation (1.8V): Extends battery life in portable devices by allowing operation down to 1.8V.
- High Speed (20MHz) in Small Package: Delivers fast processing in a 20-WFQFN, saving space.
- Integrated Brown-Out Detection: Prevents data corruption during power dips, enhancing reliability.
- Rich Peripheral Set: PWM and WDT reduce external components, lowering system cost.
Battery-Powered Remote Controls
With 1.8V operation and 2KB flash, it handles IR encoding and button debounce in TV remotes, extending battery life.
LED Lighting Controllers
PWM channels drive RGB LEDs with 20MHz speed for smooth dimming, while WDT ensures fail-safe operation in smart bulbs.
Small Sensor Hubs
128 bytes of RAM is sufficient for reading temperature or humidity sensors and sending data over I2C in IoT nodes.
Motor Speed Control in Toys
The 20MHz AVR core provides precise PWM for small DC motors, with brown-out reset preventing glitches during battery sag.
Wearable Fitness Trackers
Low voltage (1.8V) and small package (20-WFQFN) fit compact PCBs for step counting and heart-rate monitoring.
Automotive Key Fobs
Wide voltage range and robust POR make it suitable for RKE transmitters operating from coin cells.
