ATSAME51N19A-AUT

Overview

The ATSAME51N19A-AUT is an ARM Cortex-M4F microcontroller from the SAM E51 family, operating at a maximum clock frequency of 120 MHz. It features 512 KB of Flash memory and 192 KB of RAM within a 100-TQFP package. The device supports a supply voltage range of 1.71 V to 3.63 V and includes 81 I/O pins with 12-bit ADC resolution. Designed for automotive applications, it meets AEC-Q100 Grade 1 standards and operates within a temperature range of -40°C to +85°C.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Integrated floating-point unit (FPU) in the ARM Cortex-M4F core
Supports multiple communication interfaces including USB, CAN, and Ethernet
Includes hardware security features such as secure boot and encryption

Applications

Automotive body electronics and comfort systems
Infotainment system controllers
Advanced driver assistance systems (ADAS)
Industrial motor control requiring high precision

Procurement Notes

Verify the specific suffix 'AUT' confirms automotive qualification status against the manufacturer's official datasheet. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance and REACH status for regulatory adherence. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material changes that may affect integration.

Selection Notes

Select this component when automotive certification is mandatory for the target application. The 512 KB Flash and 192 KB RAM provide sufficient resources for complex firmware logic. The 120 MHz speed ensures real-time processing capabilities for safety-critical tasks. Consider pin count requirements carefully as the 100-TQFP offers 81 I/Os, which may limit usage in highly constrained form factors.

Part Context

This part belongs to the Microchip SAM E51 series, designed specifically for automotive environments. It shares architectural similarities with the SAM D51 but adds robustness and extended temperature ranges suitable for vehicle integration. The series emphasizes connectivity and security for modern embedded automotive networks.
