The ATTINY4313-SU is a low-power 8-bit AVR microcontroller from Microchip. It runs at up to 20MHz with a supply range of 1.8V to 5.5V, offering 4KB flash and 256 bytes RAM in a 20-SOIC package. Integrated features include PWM, WDT, POR, and Brown-out Reset, providing a flexible platform for compact embedded designs.
- Ultra-low voltage operation (1.8V) enables single-cell battery designs.
- 20MHz performance in a small SOIC package saves board space.
- Rich peripheral set (PWM, WDT, BOD) reduces external IC count.
- AVR core is well-documented with extensive code examples.
Portable Medical Devices
1.8V operation allows direct battery connection for glucose meters or pulse oximeters, reducing power conversion losses.
Consumer Electronics Remote Controls
The 20-SOIC package and 4KB flash support IR encoding algorithms with low standby current.
Smart Home Sensors
Use the WDT and POR to create reliable door/window sensors that wake periodically and transmit via RF.
Industrial Sensor Interfaces
256 bytes RAM is enough for buffering sensor data from SPI/I2C peripherals before processing.
Automotive Aftermarket Accessories
With -40°C to 85°C rating, it suits LED strips or seat heater controllers in vehicles.
Educational Robotics Kits
Easy-to-solder SOIC package and AVR architecture make it ideal for hobbyist motor control projects.
