MCHPATSAMD51J19A-MU
Overview
The ATSAMD51J19A-MU is a high-performance 32-bit microcontroller based on the ARM Cortex-M4F core, operating at speeds up to 120MHz. It features 512KB of Flash memory and 192KB of RAM, providing a significant performance uplift for applications transitioning from Cortex-M0+ architectures. This MCU integrates a Floating Point Unit (FPU) and a wide range of serial interfaces including QSPI and USB.
Why Choose This Part
This MCU offers a compelling mix of 120MHz processing power and a rich peripheral set including dual 12-bit DACs and 24-channel 12-bit ADCs. Its migration path within the Microchip ecosystem is seamless for engineers moving up from the SAMD21, gaining a hardware FPU without losing familiar tooling support.
