The ATTINY45-20XU is a compact AVR 8-bit MCU from Microchip Technology. It runs at 20MHz with 4KB flash and 256B RAM. Packaged in 8-TSSOP, it operates from 2.7V to 5.5V and includes PWM, brown-out reset, and watchdog timer for small-scale control applications.
- High speed 20MHz in tiny 8-pin package
- PWM output for direct load control
- Wide voltage range for 3V/5V systems
- Low pin count simplifies PCB routing
PWM Dimming
20MHz speed and PWM channels enable smooth LED dimming in lighting.
Small Motor Drivers
4KB flash is enough for brushless DC motor commutation logic.
Portable Instruments
8-pin TSSOP saves space in handheld multimeters.
Smart Sensors
WDT and BOD provide reliable wake-up and reset in environmental monitors.
Toy Controllers
Low cost and 20MHz performance suit interactive toys.
Power Tools
5.5V supply and PWM handle trigger speed control.
