The Microchip ATTINY1626-XUR is an 8-bit AVR microcontroller in a 20-SSOP package. It provides 16KB Flash and 2KB SRAM, operating at 20MHz from 1.8V to 5.5V. With integrated PWM, brown-out detection, and watchdog timer, it is well-suited for consumer and IoT applications requiring moderate memory and low power.

  • 20-SSOP package – good balance between pin count and size.
  • 16KB Flash / 2KB RAM – supports more complex firmware.
  • Low voltage operation – compatible with battery power.
  • Integrated safety features – BOD and WDT enhance reliability.

Consumer Electronics Remote Controls

20-SSOP package and low power make it ideal for IR remote transmitters with 16KB Flash for custom protocols.

Smart Lighting Systems

PWM outputs drive LED drivers in residential smart bulbs with 20MHz processing for communication stacks.

IoT Sensor Nodes

2KB RAM buffers sensor data before wireless transmission in home automation.

Battery Charger Controllers

1.8V operation and PWM enable efficient charging algorithms for portable devices.

White Goods User Interfaces

SSOP package fits on control panels for washing machines or microwaves with capacitive touch.

Data Loggers

16KB Flash stores configuration and calibration data for environmental monitoring.
