Overview

The ATTINY1626-SU is an 8-bit AVR microcontroller featuring 16KB of Flash and 2KB of RAM in a 20-pin SOIC package. Part of the tinyAVR 2 family, it operates at speeds up to 20MHz and integrates advanced analog capabilities including a 12-bit differential ADC and Configurable Custom Logic (CCL).

Why Choose This Part

This MCU offers a high-performance analog front end and an Event System that allows peripherals to communicate without CPU intervention, reducing power consumption. Its wide operating voltage of 1.8V to 5.5V and 20MHz clock speed provide flexibility for both legacy 5V systems and modern low-power designs.

Applications

Precision Sensor Interfacing
Utilizes the 12-bit differential ADC with Programmable Gain Amplifier (PGA) to measure small analog signals without external op-amps.
Low-Power Handheld Devices
Ideal for battery-operated applications requiring extremely low sleep currents of 0.4 uA and standby currents of 1 uA.
Hardware Logic Glue
The internal Configurable Custom Logic (CCL) allows for simple combinational or sequential logic tasks to be handled in hardware, reducing CPU overhead.
Industrial Control Nodes
Provides robust operation with integrated Brown-out Detection (BOD) and a hardware CRC engine for data integrity.
