The Microchip ATTINY461-20SUR is a compact 8-bit AVR microcontroller with 4KB flash and 256 bytes SRAM. It runs at up to 20MHz with a 2.7V to 5.5V supply. This 20-SOIC device integrates analog comparators, PWM, and a WDT, making it a low-cost choice for simple control and monitoring tasks.
- Compact and cost-effective: 20-SOIC package with 4KB flash reduces BOM cost for simple applications.
- Fast 20MHz operation: Provides quick response for real-time control loops.
- Wide voltage range (2.7V-5.5V): Compatible with both 3.3V and 5V systems.
- Integrated analog peripherals: ADC and comparator reduce external components.
Battery Management
Low 2.7V operation and small 4KB footprint make it ideal for fuel gauges and protection circuits in portable devices.
LED Lighting Control
PWM channels and 20MHz speed enable smooth dimming and color mixing in RGB LED drivers.
Small Appliances
Cost-effective solution for coffee makers, electric toothbrushes, and shavers with simple control logic.
Sensor Signal Conditioning
Analog comparators and ADC help process temperature or light sensor outputs with minimal external components.
Motor Control (small DC)
PWM outputs drive small brushed DC motors in toys and fans, with WDT for safety.
Consumer Electronics
20-SOIC package is easy to assemble in remote controls and small interface boards.
