ATTINY44A-SSU | Microchip AVR microcontroller | 8-bit MCU | SOIC-14 MCU
The ATTINY44A-SSU is a low-power 8-bit AVR RISC-based microcontroller from Microchip Technology, combining 4KB of In-System Programmable Flash memory with 256-byte EEPROM and 256 bytes of internal SRAM in a compact 14-pin SOIC package. Built on Microchip's picoPower technology, this tinyAVR MCU achieves up to 20 MIPS throughput at 20MHz, executing powerful instructions in single clock cycles through 32 general-purpose working registers. The device features 12 general-purpose I/O lines, an 8-channel 10-bit ADC with 12 differential channel pairs and selectable 1x/20x gain, one 8-bit and one 16-bit timer/counter with PWM capability, a Universal Serial Interface (USI) supporting SPI and I2C communication, programmable watchdog timer with on-chip oscillator, internal calibrated oscillator, and four software-selectable power-saving modes including ADC Noise Reduction and Power-down. Operating across 1.8V to 5.5V and -40°C to +85°C industrial range with brown-out detection and enhanced power-on reset, the ATtiny44A-SSU delivers flexible embedded control for cost-sensitive applications.
Applications
● Cost-sensitive consumer electronics and household appliances requiring simple embedded control with minimal external components.
● Battery-powered devices and portable instruments leveraging picoPower sleep modes for extended runtime.
● Industrial control nodes and sensor interfaces with the differential ADC measuring bridge sensors and thermocouples.
● IoT edge devices and wireless sensor nodes performing local preprocessing before communication via USI interfaces.
● Automotive accessories and aftermarket add-ons (non-qualified variant) implementing timers, PWM control, and analog monitoring.
● Hobbyist and educational projects including Arduino-compatible designs where the 14-pin DIP/SOIC form factor simplifies prototyping.
Alternative Models
1. ATTINY24A-SSU: The 2KB half-density sibling sharing identical pinout and peripherals for smaller code footprints.
2. ATTINY84A-SSU: The 8KB double-density upgrade providing 512-byte EEPROM and 512B SRAM for more complex applications.
3. ATTINY44A-PU: The through-hole PDIP-14 packaged variant for breadboard prototyping and hand-soldering applications.
4. ATTINY44A-SSN: The standard-grade SOIC-14 variant with identical specifications for commercial temperature environments.
5. ATTINY85-20SU: The 8KB single-chip alternative in SOIC-8 offering fewer I/O but more memory for compact designs.
