ATSAME53J19A-MU

Overview

The ATSAME53J19A-MU is an ARM Cortex-M4F microcontroller from the Microchip SAM E53 series, housed in a QFN-64 package. It features a 120 MHz maximum clock frequency and includes 512 kB of Flash memory alongside 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. Key peripherals include 24-channel 12-bit ADCs, dual 12-bit DACs, and interfaces such as Ethernet, USB, I2C, SPI, USART, LIN, I2S, and QSPI.

Feature Summary

• Integrated floating-point unit (FPU) for efficient mathematical processing
• Supports high-speed communication via Ethernet and USB interfaces
• Includes multiple timer/counters and DMA controllers for data handling
• Features low-power modes with brown-out detection and power-on reset

Applications

• Industrial automation controllers
• Smart home IoT devices
• Medical instrumentation
• Automotive body electronics

Procurement Notes

Verify the specific suffix 'MU' confirms the QFN-64 package variant. Confirm RoHS compliance status through official datasheets. Check moisture sensitivity level (MSL) ratings for proper storage and handling requirements before assembly.

Selection Notes

Select this model when Ethernet connectivity and USB support are required alongside moderate memory capacity. Compare against ATSAME53J19A-AU if TQFP packaging is preferred. Ensure pin compatibility and thermal performance meet design constraints for the QFN-64 form factor.

Part Context

Part of the SAM E53 family designed for cost-sensitive applications requiring robust connectivity. Shares core architecture with other J-series variants but differs in memory size and package type. Offers extended flash performance capabilities compared to standard E5x models.

Replacement Considerations

ATSAME53J19A-AU-EFP offers identical electrical specifications in a TQFP-64 package. ATSAMD51J19A-MU provides similar performance but lacks integrated Ethernet and USB peripherals.
