ATSAME51J18A-AUT

Overview

The ATSAME51J18A-AUT is a 32-bit microcontroller from the SAM E51 family, manufactured by Microchip Technology. It features an ARM Cortex-M4F core operating at 120MHz with a floating-point unit. The device includes 256KB of Flash memory and 128KB of SRAM. It supports a supply voltage range of 1.71V to 3.63V and operates within a temperature range of -40°C to +85°C. Connectivity options include CAN, Ethernet, I2C, SPI, UART/USART, and USB. The component is housed in a 64-TQFP package.

Feature Summary

Integrated floating-point unit for enhanced mathematical processing capabilities
Supports automotive applications through AEC-Q100 qualification
Includes comprehensive peripheral set with DMA, I2S, and multiple communication interfaces

Applications

Automotive infotainment systems
Industrial motor control
Smart energy metering devices

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm automotive grade status and extended temperature ratings. Ensure compatibility with required interface protocols such as CAN or Ethernet before procurement. Cross-reference datasheet revisions to account for any silicon errata updates relevant to the SAM D5x/E5x family.

Selection Notes

Select this component when automotive certification (AEC-Q100) is mandatory alongside high-performance computing needs. Compare against non-automotive variants like the ATSAMD51 series if environmental constraints are less stringent. Evaluate pin count and peripheral availability against system requirements to ensure optimal resource utilization within the 64-pin form factor.

Part Context

This part belongs to the SAM E51 family, designed for cost-sensitive automotive and industrial applications. It shares architectural similarities with the SAM D51 but adds automotive qualification. The J18 designation indicates specific memory configurations and package types within the broader SAM E5x ecosystem.
