The Microchip ATTINY45V-10MU is a high-performance, low-power 8-bit AVR microcontroller. It features 4KB of flash memory and 256 bytes of SRAM, operating at speeds up to 10MHz. With a wide voltage range of 1.8V to 5.5V, it is designed for power-sensitive applications. The device includes essential peripherals such as PWM, brown-out detection, and a watchdog timer, all housed in a compact 20-WFQFN package.
- Ultra-Low Power Consumption: Operates down to 1.8V, extending battery life in portable designs.
- Compact Footprint: The 20-WFQFN package saves PCB space for miniaturized products.
- Integrated Analog Peripherals: Includes ADC and analog comparator, reducing external component count.
- Robust Reset Features: Brown-out detection and power-on reset ensure reliable startup in unstable power conditions.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes enable long battery life in IoT and remote sensor applications.
LED Lighting Control
With built-in PWM channels and 10MHz operation, it can drive LED dimming and color control with smooth, flicker-free output.
Portable Consumer Electronics
The small 20-WFQFN package and 4KB flash make it suitable for compact devices like e-cigarettes, toys, and wearables.
Motor Control for Small Appliances
Its PWM outputs and 8-bit AVR core provide simple, cost-effective control for small DC motors in fans and pumps.
Automotive Aftermarket Accessories
Operating from -40°C to 85°C, it can handle under-hood or cabin electronics like window controllers and seat heaters.
Industrial Automation I/O Modules
The brown-out detect/reset and WDT ensure reliable operation in noisy industrial environments for simple control loops.
