MCHPATSAMD51J19A-AU
Overview
The ATSAMD51J19A-AU is a high-performance microcontroller powered by a 120MHz ARM Cortex-M4F processor with a dedicated Floating Point Unit (FPU). It is designed to handle complex computational tasks and high-speed data processing while maintaining the flexibility of the SAM D family. This variant features 512KB of Flash and 192KB of SRAM, providing ample headroom for RTOS-based applications and intensive digital signal processing.
Why Choose This Part
This MCU provides a significant performance leap over the SAMD21 series while remaining code-compatible with many Microchip software frameworks. It includes a hardware integrity check monitor and a parallel capture controller for interfacing with high-speed CMOS sensors or parallel buses.
Applications
Key Specifications
Getting Started
Development is best supported through Microchip Harmony v3 or the Atmel START web-based configuration tool. For rapid prototyping, engineers can use the SAM D51 Curiosity Nano Evaluation Kit or the Adafruit ItsyBitsy M4 Express, which shares the same architecture. The part is fully compatible with the MPLAB X IDE and the GCC ARM toolchain.
