ATSAMD51J19A-MUT

Overview

The ATSAMD51J19A-MUT is a 32-bit ARM Cortex-M4F microcontroller from the SAM D51 family, manufactured by Microchip Technology. It features a maximum clock frequency of 120 MHz and includes 512 KB of Flash program memory and 192 KB of SRAM data RAM. The device operates within a supply voltage range of 1.71 V to 3.63 V and supports an industrial temperature range of -40°C to +85°C. It is housed in a 64-QFN package with 52 available I/O pins. Key peripherals include 24-channel 12-bit ADCs, two 12-bit DACs, and interfaces such as SPI, I2C, USART, LINbus, and USB.

Feature Summary

• Integrated floating-point unit (FPU) for efficient mathematical processing
• Supports machine learning applications via dedicated hardware acceleration
• Includes multiple communication interfaces including USB and CAN-compatible LINbus
• Features advanced analog peripherals with high-resolution ADCs and DACs

Applications

• Industrial automation controllers requiring robust connectivity
• Smart home devices utilizing capacitive touch interfaces
• IoT nodes running embedded machine learning algorithms
• Medical equipment needing precise analog signal acquisition

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 64-QFN package and tape-and-reel packaging format. Confirm that the AEC-Q100 qualification status aligns with your project's automotive or industrial reliability requirements. Ensure compatibility with the 1.71V to 3.63V operating voltage range for your power design.

Selection Notes

Select this component when a balance of processing power and peripheral richness is needed in a compact QFN footprint. It is suitable for designs requiring USB connectivity and high-speed analog conversion without the need for external memory. Compare against the AU variant if TQFP packaging is preferred for easier manual assembly or prototyping.

Part Context

This MCU belongs to the SAM D51 series, which is optimized for low-power, high-performance applications. It shares architectural similarities with the ATSAME51 but lacks integrated wireless connectivity, focusing instead on wired communication and control tasks. The device is part of Microchip's broader ecosystem supporting QTouch technology and machine learning inference.

Replacement Considerations

ATSAMD51J19A-AU offers identical core specifications but uses a TQFP-64 package. ATSAMD51N19A provides more I/O pins in a 100-TQFP package. For non-FPU variants, consider the ATSAMD51P19A, though it lacks the floating-point unit.
