ATTINY426-MF

Overview

The ATtiny426-MF is an 8-bit microcontroller from the Microchip tinyAVR 2 family, featuring a 20-pin VQFN package. It integrates 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device operates at a maximum 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

Features a high-performance AVR CPU with hardware multiplier running up to 20 MHz.
Includes a 12-bit differential ADC with Programmable Gain Amplifier (PGA) for accurate analog measurements.
Supports flexible inter-peripheral signaling via an integrated Event System.
Provides versatile communication interfaces including dual USART, SPI, and TWI.

Applications

Industrial control systems requiring low-power operation
Sensor interface modules utilizing differential ADC inputs
Battery-powered devices needing extended data retention
Embedded applications using single-wire UPDI programming

Procurement Notes

Verify the specific suffix 'MF' against official Microchip documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing design constraints regarding the 20-pin VQFN footprint and operating voltage requirements before finalizing procurement.

Selection Notes

Select this component when vertical migration within the tinyAVR 2 family is required without code modification. It is suitable for designs needing 8 KB of program memory and 1 KB of RAM in a compact 20-pin form factor. Consider its extended temperature range options if operating in harsh environments.

Part Context

This part belongs to the tinyAVR 2 family, which offers pin and feature compatibility across different memory sizes. The ATtiny426 provides a balance of processing power and peripheral richness, supporting both industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges depending on the speed grade.
