Overview

The ATTINY44A-SSN is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 4KB of ISP flash memory and 256 bytes of internal SRAM. Operating at speeds up to 20MHz, this 14-pin SOIC device integrates essential peripherals like a 10-bit ADC, universal serial interface (USI), and a temperature sensor into a small footprint. It is designed for applications requiring minimal board space without sacrificing the efficiency of the AVR architecture.

Why Choose This Part

The part offers a highly efficient power-to-performance ratio, consuming only 4.4mA at 8MHz while providing 120 powerful instructions. It includes 256 bytes of EEPROM for non-volatile data storage and a programmable Brown-out Detection circuit with software disable to maximize battery life.

Applications

Portable Consumer Electronics
Ideal for battery-operated devices using its low-power sleep modes and compact 14-SOIC package.
Sensor Interface Nodes
Utilizes the integrated 10-bit ADC and temperature sensor to process analog signals at the edge.
System Logic Replacement
Replaces discrete logic or simple timing circuits with programmable control using 12 available I/O pins.
Human Interface Devices
Supports pin-change interrupts on all 12 pins, making it suitable for monitoring button matrices or encoders.
