ATSAMD51J19A-AU-EFP

Overview

The ATSAMD51J19A-AU-EFP is an ARM Cortex-M4F microcontroller from the SAM D51 family, housed in a 64-pin TQFP package. It features a maximum clock frequency of 120 MHz, 512 kB of Flash memory, and 192 kB of SRAM. The device supports a supply voltage range of 1.71 V to 3.63 V and operates within a temperature range of -40°C to +85°C. It includes 51 I/O pins, 24-channel 12-bit ADCs, and interfaces such as USB, SPI, I2C, USART, LIN, QSPI, and I2S.

Feature Summary

• Integrated floating-point unit (FPU) for efficient mathematical processing
• Automotive-grade qualification compliant with AEC-Q100 standards
• Supports machine learning applications via dedicated DSP instructions
• Includes multiple communication peripherals including USB Full-Speed

Applications

• Industrial control systems requiring robust connectivity
• Automotive infotainment and instrument clusters
• Smart home devices with sensor integration
• Medical equipment needing reliable data acquisition

Procurement Notes

Verify the specific suffix 'EFP' confirms the Tray packaging format, as other suffixes may indicate Reel or Cut Tape options. Ensure the component meets RoHS3 compliance requirements for your assembly process. Confirm that the AEC-Q100 Grade 1 rating aligns with your automotive application's thermal and reliability specifications before finalizing procurement.

Selection Notes

Select this model when a balance of high-performance computing and extensive peripheral connectivity is required in a compact surface-mount package. The inclusion of USB and CAN-capable interfaces makes it suitable for networked applications. Consider the 120 MHz speed and FPU for real-time signal processing tasks. Verify pin compatibility if replacing older SAM D series components.

Part Context

This component belongs to the Microchip SAM D51 family, designed for high-performance embedded applications. It shares architectural similarities with the ATSAME51 series but lacks integrated CAN controllers found in some E51 variants. The device is part of Microchip's strategy to provide automotive-qualified MCUs with extended flash performance for complex firmware requirements.

Replacement Considerations

ATSAMD51J19A-AU: Identical electrical specifications but may differ in packaging quantity or tray configuration. ATSAMD51J19A-AUT-EFP: Same core functionality but supplied in tape-and-reel format instead of trays.
