Microchip Technology
AVR AVR® ATtiny Microcontroller IC 8-Bit 20MHz 1KB (512 x 16) FLASH 8-SOIC
NRND219,049 in stock

Overview

The ATTINY13A-SSU is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 1KB of ISP Flash and 64 bytes of EEPROM. It operates at up to 20MHz and provides essential peripherals in a compact 8-pin SOIC package, making it ideal for simple control logic and space-constrained applications.

Why Choose This Part

It offers an excellent balance of cost and functionality with 120 powerful instructions, most of which execute in a single clock cycle. The integration of an internal oscillator and debugWIRE on-chip debugging simplifies PCB layout and accelerates the firmware development process.

Applications

Battery-Powered Logic
Utilizes low-power sleep modes and a 24uA sleep current for extending life in portable devices.
Simple Sensor Interface
Integrates a 4-channel 10-bit ADC to monitor analog inputs and perform local signal processing.
PWM Power Control
Features two PWM channels for driving LEDs or small DC motors in cost-sensitive designs.
System Supervisor
Acts as a watchdog or power sequencer for larger systems using its internal programmable watchdog timer.
