ATTINY1627-MUR

Overview

The ATtiny1627-MUR is an 8-bit AVR microcontroller from the tinyAVR® 2 family, operating at up to 20 MHz. It features 16 KB of Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device includes a 12-bit differential ADC with a Programmable Gain Amplifier (PGA), four Configurable Custom Logic (CCL) Look-Up Tables, and multiple timers including TCA, TCB, and RTC. It supports I²C, SPI, and USART interfaces via UPDI. The -MUR suffix indicates a 24-pin VQFN package in Tape & Reel format, rated for -40°C to +85°C.

Feature Summary

• Integrates a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
• Features a 12-bit differential ADC with PGA and scalable analog comparator inputs for precise signal acquisition.
• Includes an Event System for CPU-independent peripheral communication and Configurable Custom Logic (CCL).
• Supports three sleep modes: Idle, Standby, and Power-Down with full data retention.

Applications

• High-precision sensor nodes such as smoke, PIR, and pressure sensors.
• Real-time control systems like power converters and safety monitoring.
• Analog interface chips for larger MCUs/MPUs in noisy environments.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. Ensure the component matches the required pin count and memory configuration for your design. Cross-reference the part number with official Microchip documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this model when 24 pins and 16 KB of program memory are required within the tinyAVR® 2 family. It offers vertical migration compatibility with other devices in the series without code modification. Consider the integrated analog peripherals if high-resolution sensing or custom logic implementation is needed for the application.

Part Context

This device belongs to the tinyAVR® 2 family, which provides flexible low-power architecture. The ATtiny1627 variant specifically targets applications requiring higher I/O counts and advanced analog features compared to smaller pin-count siblings. It shares architectural similarities with the ATtiny1624 and ATtiny1626.
