ATTINY1616-MN

Overview

The ATTINY1616-MN is an 8-bit microcontroller from the tinyAVR 1-series, featuring a 20 MHz AVR CPU with hardware multiplier. It includes 16 KB Flash, 2 KB SRAM, and 256 bytes EEPROM. The device operates between 1.8 V and 5.5 V within -40°C to +105°C. Key peripherals include a 12-bit TCD, 16-bit TCA/TCB timers, USART, SPI, TWI, two 10-bit ADCs, three 8-bit DACs, and a Peripheral Touch Controller (PTC). It utilizes a single-pin UPDI interface for programming and debugging.

Feature Summary

• Integrates Core Independent Peripherals (CIPs) such as the 12-bit Timer/Counter Type D for control applications and a Peripheral Touch Controller for capacitive touch interfaces.
• Supports low-power operation through multiple sleep modes including Idle, Standby, and Power-Down with full data retention.
• Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic for flexible digital logic implementation.

Applications

• Capacitive touch sensing applications utilizing Driven Shield+ technology
• Industrial control systems requiring precise timing via dedicated timer modules
• Low-power embedded devices operating on battery or limited power supplies

Procurement Notes

Verify the specific suffix 'MN' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding the SOIC-20 package dimensions and thermal characteristics. Confirm that the required peripheral configurations align with the silicon errata and data sheet clarifications provided by the manufacturer.

Selection Notes

Select this component when a balance of processing speed and analog capabilities is required in a compact form factor. The inclusion of both standard communication interfaces and advanced touch control features makes it suitable for complex user interfaces. Consider the available I/O multiplexing options to optimize pin usage for specific application layouts.

Part Context

This part belongs to the ATtiny1614/1616/1617 family within the tinyAVR 1-series. These microcontrollers share a common architecture but differ in memory size and I/O count. The 1616 variant specifically offers 16 KB of Flash memory and is housed in a 20-pin package, positioning it between the smaller 14-pin and larger 24-pin options in terms of resource availability.

Replacement Considerations

Direct replacements within the same series include ATTINY1614 and ATTINY1617, subject to pinout and memory differences. Cross-series migration may require significant firmware and hardware redesign due to architectural changes in the AVR core and peripheral sets.
