ATTINY3227-MUR

Overview

The ATtiny3227-MUR is a member of the tinyAVR® 2 family, featuring an 8-bit AVR CPU with hardware multiplier and up to 20 MHz operation. It provides 32 KB Flash, 3 KB SRAM, and 256B EEPROM in a 24-pin VQFN package. The device includes a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and an Event System. Operating voltage ranges from 1.8V to 5.5V, supporting industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature grades.

Feature Summary

High-performance low-power architecture with single-cycle I/O access and vectored interrupts
Advanced analog features including a 12-bit differential ADC with Programmable Gain Amplifier (PGA)
Flexible peripheral set with Event System for inter-peripheral signaling and Configurable Custom Logic (CCL)
Single-pin Unified Program and Debug Interface (UPDI) for programming and debugging

Applications

General-purpose embedded control systems
Industrial sensor interfaces
Battery-powered devices requiring low power consumption
Automotive applications (VAO variants)

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, temperature range, and variant status. Ensure compatibility with existing design constraints before procurement. Confirm availability through authorized distributors or direct channels.

Selection Notes

Select this component for designs requiring high pin count within a small footprint and advanced analog capabilities. Consider the 24-pin VQFN package for space-constrained applications. Evaluate speed grades relative to operating voltage requirements for optimal power efficiency.

Part Context

Part of the tinyAVR® 2 family, offering vertical migration compatibility with other devices in the series without code modification. Designed for applications needing increased memory and peripherals compared to previous generations while maintaining low power consumption.
