The ATTINY461A-SU is a compact 8-bit AVR microcontroller from Microchip Technology, featuring 4KB Flash and 256B SRAM. With a 1.8V-5.5V supply range and 20MHz operation, it provides a balanced mix of performance and simplicity. The 20-SOIC package and integrated PWM/comparator make it a reliable choice for consumer and industrial control.
- Wide Supply Range: Works with both 3.3V and 5V systems without level shifters.
- Fast 20MHz Execution: Handles real-time control loops efficiently.
- Easy-to-Use SOIC Package: Simplifies PCB layout and manual assembly.
- Integrated PWM: Reduces external timer components.
- Low Power Consumption: Suitable for battery-operated devices.
Small Appliance Control
20MHz speed and PWM enable precise control of blenders, fans, and coffee makers.
LED Lighting Drivers
PWM channels and 5.5V operation directly drive LED strings with external MOSFETs.
Security Keypads
4KB Flash stores encryption keys and debounce logic for access control systems.
Battery Chargers
ADC and comparator monitor charge current and voltage for NiMH or Li-ion batteries.
Toys and Hobby Electronics
Low cost and SOIC package make it ideal for RC servos and simple robots.
Environmental Monitors
Low-power sleep modes allow long-term temperature and humidity logging.
