The Microchip ATTINY4313-SUR is an 8-bit AVR microcontroller featuring 4KB flash and 256B SRAM in a 20-SOIC package. Running at up to 20MHz with a 1.8V-5.5V supply, it integrates brown-out detection, POR, PWM, and WDT. Its high speed and small footprint make it a cost-effective solution for consumer and hobbyist applications.
- High speed (20MHz): Provides faster response for time-critical control loops.
- Wide voltage range: Works with both 3.3V and 5V systems without level shifters.
- Easy-to-use SOIC package: Compatible with standard PCB assembly and breadboard adapters.
- Integrated PWM: Simplifies motor and LED control without external timers.
Consumer Appliances
The 20MHz speed and 4KB flash are ideal for microwave oven control panels or washing machine timers.
Hobbyist Robotics
Its SOIC package is easy to solder, making it perfect for DIY robot controllers with servo PWM outputs.
Lighting Control
PWM channels can drive LED dimmers or RGB color mixers in smart home lighting systems.
Security Systems
With WDT and low-power modes, it can monitor door sensors and send alerts in alarm panels.
Data Loggers
256 bytes of SRAM can store small sensor readings before writing to external EEPROM.
Educational Kits
Its simple architecture and DIP-compatible SOIC footprint make it a great teaching tool for embedded systems.
