The Microchip ATTINY45V-10MUR is a low-power 8-bit AVR microcontroller in a tiny 20-WFQFN package. It operates from 1.8V to 5.5V at up to 10MHz, with 4KB Flash and 256B SRAM. Features include PWM, Brown-out Detection, Power-on Reset, and Watchdog Timer. This MCU is designed for space-constrained, battery-operated applications requiring minimal power and small footprint.
- Ultra-Compact 20-WFQFN (3x3mm): Fits into the smallest PCB designs, ideal for wearables and mini modules.
- 1.8V Operation: Works with a single alkaline cell or lithium battery without boost converters.
- Low Power Modes: Power-down mode draws less than 1µA, extending battery life in intermittent applications.
- Integrated PWM & ADC: Reduces external components for sensor and actuator interfacing.
Miniature LED Lighting
The 20-WFQFN package (3x3mm) and PWM channels make it perfect for RGB LED controllers in compact fixtures or decorative lighting.
Small Motor Drivers
Drive micro DC motors in toys or haptic feedback devices using the PWM outputs, with the 1.8V operation allowing single-cell battery use.
Sensor Conditioning
Read analog sensors with the 8-bit ADC and output calibrated digital signals via I2C, ideal for smart sensors in industrial settings.
Battery Management
Monitor voltage and temperature in single-cell LiPo packs, using the WDT to ensure safe shutdown in over-discharge conditions.
Disposable Medical Sensors
The low cost and small size enable single-use diagnostic strips that measure and transmit data wirelessly.
Smart Toys
Add interactive features like sound generation and motion detection to toys, with the low-power modes preserving battery life during idle periods.
