MCHPATSAMD51N19A-AFT
Overview
The ATSAMD51N19A-AFT is a high-performance 32-bit microcontroller featuring an ARM Cortex-M4F core with a Floating Point Unit (FPU) operating at speeds up to 120MHz. It integrates 512KB of Flash and 192KB of RAM, providing a robust platform for complex embedded algorithms and data-heavy applications. This device is designed for low power consumption, drawing as little as 0.5uA in shutdown mode while maintaining high processing throughput.
Why Choose This Part
The combination of a 120MHz Cortex-M4F and a low 2.8mA active current at full speed makes it highly efficient for battery-powered yet compute-intensive designs. Extensive peripheral support, including dual 12-bit DACs and 10 16-bit timers, allows for significant hardware-level task offloading.
Applications
Key Specifications
Getting Started
Develop using Microchip Studio or MPLAB X IDE with the XC32 compiler. For rapid prototyping, the SAM D51 Curiosity Nano or Adafruit Grand Central M4 Express are common hardware platforms that support this family. Ensure proper decoupling for the 100-TQFP package and utilize the Atmel Software Framework (ASF4) or Harmony for peripheral driver generation.
