ATSAMD51P19A-AUT-EFP

Overview

The ATSAMD51P19A-AUT-EFP is a 32-bit ARM Cortex-M4F microcontroller from the SAM D5x family, operating at a maximum clock frequency of 120 MHz. It features 512 kB of Flash memory and 192 kB of SRAM within a 100-TQFP package. The device supports a supply voltage range of 1.71 V to 3.63 V and includes integrated USB, CAN, Ethernet, I2C, SPI, and USART interfaces. It is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

Integrated Ethernet MAC with dedicated DMA controller
Automotive qualification compliant with AEC-Q100 Grade 1 standards
Hardware-accelerated cryptographic operations via AES and SHA-256 modules

Applications

Automotive telematics control units
In-vehicle infotainment systems
Industrial IoT gateways with wired connectivity
Smart sensor nodes requiring deterministic communication

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 100-TQFP form factor. Cross-reference the datasheet revision history for any silicon errata or design guideline updates relevant to the manufacturing lot.

Selection Notes

Select this component when both high-speed Ethernet connectivity and automotive reliability are required. It serves as an upgrade path for designs previously using non-automotive SAM D51 variants lacking Ethernet peripherals. Evaluate pin count requirements carefully as the 100-TQFP offers a specific balance of I/O density.

Part Context

This part belongs to the SAM D5x family, which bridges consumer performance with automotive durability. Unlike the J-series (64-pin) or N-series (100-pin without Ethernet), the P-series specifically integrates an Ethernet MAC. This distinguishes it within the broader ATSAMD51 portfolio by enabling direct wired network integration in compact automotive enclosures.
