ATTINY3227-MFR

Overview

The ATtiny3227-MFR is a member of the tinyAVR® 2 family, featuring an AVR CPU with hardware multiplier running at up to 20 MHz. 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, Event System, CCL, USART, SPI, TWI, TCA, TCB, RTC, UPDI, and supports 1.8V to 5.5V operation.

Feature Summary

• High-performance low-power AVR CPU with hardware multiplier
• Advanced analog features including 12-bit differential ADC with PGA
• Flexible event system for inter-peripheral signaling
• Configurable Custom Logic (CCL) with programmable Look-Up Tables

Applications

• Industrial control systems
• Smart energy metering
• Sensor interfaces
• General-purpose embedded applications

Procurement Notes

Verify the MFR suffix indicates tape and reel packaging. Confirm the part number corresponds to the standard temperature range (-40°C to +85°C). Ensure compatibility with existing designs by checking pinout against the 24-pin VQFN variant. Cross-reference datasheet DS40002345B for specific electrical characteristics.

Selection Notes

Select this model for applications requiring high peripheral density and advanced analog capabilities within a compact 24-pin footprint. Consider the vertical migration path from smaller pin-count devices if code reuse is desired. Evaluate the 12-bit ADC resolution and PGA requirements against sensor signal levels.

Part Context

This component belongs to the tinyAVR® 2 family, designed for enhanced performance and low power consumption. It shares architectural similarities with other members like ATtiny3224 and ATtiny3226 but offers the highest pin count and I/O availability in the series.
