Microchip ATTINY416-MNR: A Comprehensive Technical Overview

The Microchip ATTINY416-MNR is a powerful representative of the modern AVR® microcontroller family, engineered to deliver high performance and flexibility in an ultra-compact form factor. This device is a cornerstone for designers creating sophisticated, power-sensitive applications where physical space is at a premium. As part of the robust tinyAVR® 1-series, it packs a surprising array of features that make it suitable for a wide range of embedded control tasks, from consumer electronics and IoT nodes to industrial automation and motor control.

Core Architecture and Performance

At the heart of the ATTINY416 lies the high-performance 8-bit AVR® RISC CPU. This core can achieve a throughput of up to 20 MIPS at 20 MHz, ensuring responsive and efficient execution of control algorithms. The core is augmented with a hardware multiplier, which accelerates arithmetic operations, a critical feature for digital signal processing (DSP) and other compute-intensive tasks. The microcontroller operates within a wide voltage range (1.8V to 5.5V), making it compatible with various power sources, including batteries, and is designed for ultra-low-power operation, supporting multiple sleep modes.

Memory Configuration

The memory subsystem of the ATTINY416 is thoughtfully designed for data-intensive applications. It features 4 KB of Flash memory for storing application code, 512 Bytes of SRAM for volatile data handling, and 128 Bytes of EEPROM for retaining critical data even when power is removed. This balanced memory configuration allows developers to implement complex state machines and data logging functionalities.

Advanced Peripherals and System Integration

A key strength of the ATTINY416-MNR is its rich set of integrated peripherals, which significantly reduces the need for external components, lowering overall system cost and complexity.

Analog Capabilities: It includes a 10-bit 130 kSPS Analog-to-Digital Converter (ADC) with up to 11 channels, a 10-bit Digital-to-Analog Converter (DAC), and analog comparators. This suite of analog peripherals is ideal for precision sensor interfacing and closed-loop control systems.

Timers and Control: The device is equipped with multiple 16-bit timers/counters (TCA and TCB), which are essential for generating Pulse-Width Modulation (PWM) signals for motor control, measuring frequency, and creating precise timing events.

Communication Interfaces: Modern connectivity is provided by a Universal Serial Interface (USART), an I2C compatible Two-Wire Interface (TWI), and an SPI compatible Serial Peripheral Interface (SPI). These standard communication protocols enable seamless connection with a vast ecosystem of sensors, displays, and other peripheral ICs.

Configurable Custom Logic (CCL): This innovative peripheral allows for the creation of simple logic functions directly in hardware, without CPU intervention. This can be used to interface peripherals, create custom pulse sequences, or reduce external glue logic, further optimizing system design.

Package and Development Support

The ATTINY416-MNR comes in a 20-pin QFN package with a compact 3x3 mm footprint. The "MNR" suffix specifically denotes the tape-and-reel packaging for high-volume manufacturing. Development is supported by the Atmel Studio and Microchip MPLAB® X IDE environments, along with the MPLAB XC8 compiler. For rapid prototyping, the device is fully compatible with the Microchip Curiosity Nano evaluation board.
