ATTINY416-MNR

Overview

The ATTINY416-MNR is an 8-bit AVR microcontroller from the tinyAVR 1 series, featuring a high-performance RISC architecture capable of operating at frequencies up to 20MHz. It integrates 4KB of system-in-programmable flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM within a 20-VQFN package. The device supports a supply voltage range of 1.8V to 5.5V and operates across industrial temperature ranges. Key peripherals include a 10-bit ADC, 8-bit DAC, USART, SPI, TWI, and a Peripheral Touch Controller for capacitive touch interfaces.

Feature Summary

• Integrates a Peripheral Touch Controller with drive shielding capabilities for robust capacitive touch sensing in noisy environments.
• Features a comprehensive event system allowing direct peripheral-to-peripheral communication without CPU intervention.
• Includes configurable custom logic (CCL) with programmable look-up tables for implementing complex digital functions.
• Supports low-power operation through multiple sleep modes and SleepWalking functionality for peripheral-driven wake-ups.

Applications

• Capacitive touch interface controllers for consumer electronics
• Industrial sensor nodes requiring low power consumption
• Battery-powered portable devices
• General-purpose embedded control systems

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-VQFN form factor. Confirm moisture sensitivity level requirements for assembly processes. Cross-reference part numbers with current datasheets to avoid obsolete variants.

Selection Notes

Select this component when a balance of processing speed and peripheral richness is required in a compact footprint. The integrated touch controller makes it suitable for user interface applications. Consider the 20MHz clock speed for timing-critical tasks. Evaluate the 1.8V to 5.5V supply range for flexibility in power design.

Part Context

This part belongs to the tinyAVR 1 family, designed for cost-sensitive applications requiring functional safety features. It shares architectural similarities with other ATtiny4xx/8xx models but offers specific pin counts and peripheral sets. The MNR suffix typically denotes a tape and reel packaging option for automated assembly.

Replacement Considerations

Check for ATTINY416-MN or ATTINY816-MNR equivalents if different memory sizes or packages are acceptable. Verify pinout compatibility before substituting with other AVR microcontrollers. Consult official cross-reference guides for validated alternatives.
