The ATTINY2313-20SU is a low-power 8-bit AVR microcontroller from Microchip in a 20-SOIC package. It runs at up to 20MHz with 2KB flash and 128 bytes RAM, operating from 2.7V to 5.5V. Integrated features include PWM, watchdog timer, and brown-out reset, making it a compact solution for simple control and interface tasks.
- High speed-to-power ratio – 20MHz at low current draw for efficient processing.
- Wide SOIC package – easier manual soldering and better thermal performance.
- Hardware USART – simplifies serial communication with PCs or other MCUs.
- Mature AVR architecture – extensive code examples and toolchain support.
Simple Motor Controllers
20MHz speed and PWM support enable basic brushed DC motor speed control.
Sensor Signal Conditioning
Analog comparator and interrupt pins allow quick threshold detection for proximity sensors.
Protocol Conversion (UART/I2C)
Hardware USART and I2C interfaces bridge legacy sensors to modern microcontrollers.
Battery Management in Portable Devices
Low-power sleep modes and 2.7V operation extend runtime in handheld tools.
LED Matrix Displays
Sufficient I/O pins and timers drive 8x8 LED matrices with multiplexing.
Automotive Aftermarket Accessories
Wide SOIC package and -40°C to 85°C range suit retrofit alarm or lighting modules.
