MCHPATSAME51N20A-AZVAO
Overview
ATSAME51N20A-AZVAO is a Microchip SAM E51-series ARM Cortex-M4 microcontroller in a 100-pin TQFP package. It is aimed at embedded control and connected applications that need a 32-bit MCU with integrated USB and CAN support, along with a generous 1 MB flash memory size. The extended-temperature rating makes it suitable for more demanding industrial environments.
Why Choose This Part
This part combines a Cortex-M4 core with a high-capacity flash footprint and integrated wired interfaces, which can reduce the need for external companion chips. The 100-pin TQFP package gives a practical balance between peripheral count and board complexity for medium-density designs. Extended-temperature availability is useful when the design must survive harsher industrial operating conditions.
Applications
Getting Started
Start with Microchip's SAM E51 Xplained Pro ecosystem or a compatible SAM E51 evaluation board to validate the peripheral mix and tool flow before committing to custom hardware. Microchip's MPLAB X IDE and XC32 toolchain are the normal development path, and the device is supported by the usual Microchip programming/debug hardware such as Atmel-ICE. For first bring-up, verify clocking, USB power and signal integrity, and CAN transceiver selection early in the design.
