The Microchip ATTINY461-20SU is a low-power 8-bit AVR MCU with 4KB flash and 256 bytes RAM. Operating at 20MHz and 2.7-5.5V, it includes PWM, brown-out detection, and a watchdog timer. Housed in a 20-SOIC package, it is ideal for cost-sensitive applications like remote controls, LED lighting, and small appliances.
- Ultra-Low Power: Optimized for battery operation with multiple sleep modes and fast wake-up.
- Compact and Cost-Effective: 20-SOIC package and small memory footprint reduce BOM cost.
- Wide Voltage Range: 2.7V-5.5V simplifies design with both 3.3V and 5V peripherals.
- Integrated Analog: ADC and analog comparator reduce external components for sensor interfaces.
Battery-Powered Remote Controls
Low power consumption and 2.7V operation extend battery life in IR/RF remotes for TVs, fans, and garage doors.
LED Lighting Effects
PWM outputs drive RGB LEDs for decorative lighting, with small code footprint for color fading and strobe patterns.
Small Appliance Timers
Simple timer and counter functions control microwave ovens, coffee makers, and washing machine cycles with minimal external parts.
Sensor Signal Conditioning
Internal ADC reads temperature, light, or pressure sensors and outputs digital signals to a host MCU or display.
Toy and Hobby Electronics
Compact 20-SOIC package and 5V operation make it ideal for RC servos, simple robots, and electronic games.
Power Supply Monitoring
Brown-out detection and WDT provide safe shutdown and reset in low-cost power supplies and chargers.
