The Microchip ATTINY13A-SFR is a high-performance 8-bit AVR microcontroller in a compact 8-SOIC package. It delivers 1KB of flash memory and 64 bytes of SRAM, operating from 1.8V to 5.5V at speeds up to 20MHz. Built-in features like PWM, brown-out detection, and a watchdog timer make it ideal for cost-sensitive embedded control tasks.
- Ultra-low voltage operation (1.8V) – enables direct battery power without regulators, reducing BOM cost.
- High temperature rating (125°C) – suitable for automotive and industrial environments where standard MCUs fail.
- Integrated PWM and WDT – reduces external components, simplifying PCB design and improving reliability.
- 20MHz performance in an 8-pin package – delivers high throughput for space-constrained applications.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes allow the ATTINY13A-SFR to run directly from a single lithium cell or two alkaline batteries, extending operational life in remote IoT sensors.
LED Dimming and Lighting Control
With an internal PWM peripheral and 20MHz operation, this MCU can generate high-frequency dimming signals for LED drivers, enabling smooth, flicker-free brightness control in architectural lighting.
Small Appliance Timers
The integrated WDT and brown-out detection ensure reliable timing sequences in coffee makers or microwave ovens, preventing system lockups during voltage dips.
Motor Speed Controllers (Brushed DC)
Using the PWM output and 125°C rated temperature, this chip can drive small brushed DC motors in automotive or industrial actuators, with the high temp rating ensuring reliability under hood.
Portable Health Monitors
The 64 bytes of SRAM and 1KB flash are sufficient for simple heart-rate or temperature monitoring algorithms, while the small SOIC package fits compact wearable PCBs.
Smart Toy Controllers
Its low pin count and 5.5V max supply simplify interfacing with hobby servos and LEDs, while the 20MHz speed allows responsive interactive behavior in toys.
