Overview

Description

Introduction to ATtiny4313-MU
- What it is: An 8-bit AVR microcontroller from Atmel/Microchip, part of the Tiny family. Package: 20-pin MU (SOIC-20).
- Core and speed: AVR RISC core, up to about 8 MHz operation, typically from 2.7 to 5.5 V.
- Memory: around 4 KB of Flash, 256 B EEPROM, ~128 B RAM.
- Peripherals: 4-channel 10-bit ADC; Timer/Counter0 (8-bit) and Timer/Counter1 (16-bit) with PWM; USI serial interface (SPI/I2C); watchdog timer; analog comparator; multiple sleep modes; brown-out detection.
- Programming: In-system programmable via SPI; supported by AVR-GCC and avrdude.
- Use cases: Small embedded control tasks, sensors, LED drivers, hobby projects requiring low pin count and modest resources.
- Note: Lacks USB/UART hardware on some variants; for more flash/RAM or USB capabilities, consider larger AVR models.
