ATTINY1616-MFR

Overview

The ATTINY1616-MFR is an 8-bit AVR microcontroller from the tinyAVR 1-series, housed in a 20-pin VQFN package. It features a 16 KB Flash memory, 2 KB SRAM, and 256 bytes EEPROM. The device operates at up to 20 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include two 10-bit ADCs, three 8-bit DACs, one USART, one SPI, and one TWI interface. It supports extended temperature ranges up to 125°C.

Feature Summary

• Integrated Peripheral Touch Controller (PTC) for capacitive touch sensing
• Configurable Custom Logic (CCL) for hardware logic implementation
• Event System for CPU-independent peripheral signaling
• Single-pin Unified Program and Debug Interface (UPDI)

Applications

• Capacitive touch user interfaces
• Industrial control systems
• Low-power sensor nodes

Procurement Notes

Verify the MFR suffix indicates automotive qualification or specific manufacturing origin requirements. Confirm the package type matches the design footprint. Check for RoHS compliance status. Ensure the operating temperature grade meets system specifications.

Selection Notes

Select this model for applications requiring high I/O count in a compact VQFN package. Consider the PTC capabilities if touch input is needed. Verify that the 20 MHz speed grade aligns with power consumption constraints. Compare against other series members for pin compatibility.

Part Context

This component belongs to the ATtiny1614/1616/1617 family within the tinyAVR 1-series. These devices share a common architecture but differ in package options and memory configurations. The MFR suffix typically denotes specific automotive or industrial grading variations within the standard product line.

Replacement Considerations

Direct replacements include other variants in the ATtiny1614/1616/1617 family with compatible packages. Cross-reference pinouts for SOIC-20 equivalents if package changes are permissible.
