ATTINY426-MFR

Overview

The ATtiny426-MFR is an 8-bit microcontroller from the Microchip tinyAVR 2 family, featuring a 20-pin VQFN package. It integrates 4 KB of Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and an Event System.

Feature Summary

High-performance AVR CPU with hardware multiplier running up to 20 MHz
12-bit differential ADC with Programmable Gain Amplifier (PGA)
Event System for CPU-independent peripheral signaling
Configurable Custom Logic (CCL) with four Look-Up Tables

Applications

Industrial control systems requiring low power consumption
Sensor interfaces utilizing high-resolution analog-to-digital conversion
Communication nodes using USART or SPI protocols
Battery-powered devices benefiting from multiple sleep modes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding pin count and memory size before finalizing procurement decisions.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is required without code modification. Consider the 20-pin form factor for balanced I/O availability and compare memory specifications against larger variants like the ATtiny826 if additional storage is needed.

Part Context

This part belongs to the tinyAVR 2 family, designed for flexible low-power applications. It shares architectural similarities with the ATtiny424 and ATtiny427, differing primarily in pin count and available I/O resources while maintaining feature compatibility across the series.
