ATTINY1616-MNR

Overview

The ATTINY1616-MNR is an 8-bit microcontroller from the tinyAVR 1-series, utilizing the AVR core with a hardware multiplier. It features 16 KB of in-system self-programmable Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock frequencies up to 20 MHz and supports supply voltages between 1.8 V and 5.5 V. It includes a Peripheral Touch Controller (PTC), Event System, and Core Independent Peripherals. The component is housed in a 20-pin SOIC package and offers 18 programmable I/O lines.

Feature Summary

• Integrates a Peripheral Touch Controller (PTC) supporting capacitive touch interfaces with Driven Shield+ technology for enhanced noise handling.
• Features Core Independent Peripherals (CIPs) and an Event System for CPU-independent inter-peripheral signaling and predictable operation.
• Includes multiple analog peripherals such as two 10-bit ADCs, three 8-bit DACs, and three Analog Comparators with low propagation delay.
• Supports single-pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

• Capacitive touch interface implementations
• Low-power embedded control systems
• Industrial monitoring applications

Procurement Notes

Verify the specific suffix 'MNR' against official Microchip documentation to confirm the reel packaging format and temperature grade. Ensure the ordering part number matches the exact silicon revision and package variant required for your design. Cross-reference the datasheet DS40002204A for any errata or clarification documents relevant to this specific batch.

Selection Notes

Select this model when a 20-pin package with 18 I/O lines is required alongside integrated capacitive touch sensing capabilities. Consider the 16 KB Flash size and 20 MHz performance for applications needing moderate processing power with low power consumption. Verify that the operating voltage range of 1.8 V to 5.5 V aligns with the system power rails.

Part Context

This component belongs to the ATtiny1614/1616/1617 family within the tinyAVR 1-series. These microcontrollers share a common architecture but differ in pin counts and peripheral availability. The 1616 variant specifically provides a balance of memory and I/O options suitable for compact designs requiring advanced analog and touch features.

Replacement Considerations

Check for ATTINY1616-SN or ATTINY1616-SSU if different packaging is needed. Verify compatibility with ATTINY3216 if additional memory is required, noting potential pinout differences.

FAQ
