ATTINY1627-MFR

Overview

The ATTINY1627-MFR 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 B of EEPROM. The device provides 22 programmable I/O pins in a 24-pin VQFN package. Key peripherals include a 12-bit differential ADC with PGA, four CCL LUTs, two TCB timers, one TCA timer, USART, SPI, and TWI interfaces.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
• Includes advanced analog capabilities such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
• Supports CPU-independent inter-peripheral signaling via the Event System and Configurable Custom Logic (CCL).
• Offers flexible clock options including internal oscillators and external crystal support for precise timing.

Applications

• Sensor nodes requiring smart analog processing.
• Real-time control systems like power converters.
• Space-constrained industrial and consumer applications.
• Automotive sensor interfaces meeting AEC-Q100 requirements.

Procurement Notes

Verify the specific suffix 'MFR' against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing designs by checking pinout alignment within the tinyAVR® 2 family. Confirm that the ordered variant matches the required voltage and frequency specifications for the target application environment.

Selection Notes

Select this component for applications needing vertical migration within the tinyAVR® 2 family without code modification. Consider its 24-pin VQFN package for layout optimization in space-limited designs. Evaluate its analog performance if signal conditioning is required before digital processing. Check speed grades against supply voltage constraints for stable operation.

Part Context

This part belongs to the tinyAVR® 2 family, which shares pin and feature compatibility across variants. It offers horizontal migration options to lower pin counts or vertical scaling to different memory sizes. The family utilizes modern Microchip technologies for low-power and high-performance embedded control.

Replacement Considerations

Compatible substitutes include other ATtiny162x devices within the same family, such as ATtiny1626 or ATtiny1624, provided pin count and peripheral requirements are met. Verify package availability and electrical characteristics for direct replacement.
