Overview

The ATTINY3216-SNR is a high-performance 8-bit AVR microcontroller featuring 32KB of Flash and a 20MHz internal oscillator. Part of the tinyAVR 1-series, it utilizes the latest Core Independent Peripherals (CIPs) to reduce CPU overhead and power consumption in a compact SOIC20 package.

Why Choose This Part

The 32KB Flash capacity provides significant headroom for complex C++ libraries or RTOS implementations in a small footprint. Its Event System allows peripherals to communicate directly without CPU intervention, ensuring deterministic response times and reduced power draw.

Applications

Sensor Node Interface
Using the dual 12-bit ADCs and programmable gain amplifier to interface with multiple analog sensors in industrial environments.
Safety-Critical Monitoring
Implementing the hardware-based Cyclic Redundancy Check (CRC) and Windowed Watchdog Timer (WWDT) for system health monitoring.
Portable Electronics
Leveraging low-power sleep modes and the Event System for battery-operated devices requiring 32KB of program space.

Getting Started

Develop using Microchip Studio or MPLAB X IDE with the XC8 compiler. Hardware debugging and programming are performed via the Unified Program and Debug Interface (UPDI), typically using an MPLAB PICkit 4 or the cost-effective Atmel-ICE.

Also Consider

ATMEGA328P-PU MCHPMicrochip Technology - A traditional AVR architecture with similar memory capacity but in a larger DIP28 package for through-hole prototyping.
