The Microchip ATTINY461A is a low-power 8-bit AVR microcontroller in a compact 20-TSSOP package. It operates from 1.8V to 5.5V and runs at up to 20MHz. With 4KB of flash memory, 256 bytes of RAM, and integrated peripherals like PWM, a temperature sensor, and a watchdog timer, it is designed for cost-sensitive embedded control tasks. Its small footprint and robust feature set make it a practical choice for portable and industrial applications.
- Wide voltage range (1.8V-5.5V): Simplifies power supply design and supports direct battery operation.
- Integrated temperature sensor: Eliminates external sensing components, reducing BOM cost and board space.
- 20MHz AVR core: Provides fast instruction execution for real-time control loops.
- 20-pin TSSOP package: Enables compact PCB layouts for space-limited products.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes enable long battery life in remote environmental or industrial sensors.
LED Lighting Control
With PWM channels and a 20MHz AVR core, it can generate smooth dimming and color-mixing signals for RGB LED drivers.
Temperature Monitoring Systems
The built-in temperature sensor simplifies designs for over-temperature alarms or data logging without adding external thermistors.
Motor Speed Controllers
PWM outputs and a watchdog timer allow reliable open-loop speed control for small DC or brushed motors in appliances.
Portable Consumer Electronics
The 4KB flash and 256B RAM are sufficient for simple user interfaces, haptic feedback, or power management in handheld gadgets.
Automotive Interior Modules
With a -40°C to 85°C range and brown-out detection, it suits interior lighting or switch-reading modules in vehicles.
