ATSAME53J20A-MUT

Overview

The ATSAME53J20A-MUT is a 32-bit microcontroller from the Microchip SAM E53 family, featuring an ARM Cortex-M4F core with a floating-point unit. It operates at a maximum frequency of 120 MHz and includes 1 MB of in-system programmable Flash memory and 256 KB of SRAM. The device provides 51 general-purpose I/Os and integrates multiple communication interfaces including USB, Ethernet, I2C, SPI, USART, LINbus, QSPI, and I2S. It supports A/D conversion via 24 channels of 12-bit ADCs and features two 12-bit D/A converters. Operating within a temperature range of -40°C to +85°C, it utilizes a 64-pin QFN package.

Feature Summary

• Integrated Ethernet MAC and PHY for network connectivity
• USB Full-Speed controller supporting device and host modes
• Hardware cryptographic accelerators for secure data processing
• Low-power modes with fast wake-up capabilities

Applications

• Industrial automation controllers
• Smart home gateways
• Medical instrumentation
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 64-pin QFN package and industrial temperature grade during sourcing. Confirm RoHS compliance status as per current manufacturer declarations. Ensure compatibility with existing PCB footprints designed for QFN-64 components. Check for any recent PCN notifications regarding assembly sites or material changes that may affect long-term supply stability.

Selection Notes

Select this component when both Ethernet and USB connectivity are required alongside high-performance computing. Compare pin counts against ATSAMD51 series if fewer I/Os suffice. Evaluate power consumption requirements against SAM D5x series for ultra-low-power applications. Consider package availability constraints between TQFP and QFN options based on manufacturing equipment.

Part Context

This MCU belongs to the SAM E53 family, which extends the SAM D5x architecture with enhanced security and connectivity features. It shares the same core architecture but adds dedicated hardware for Ethernet and advanced cryptographic operations. The family targets applications requiring robust real-time control combined with secure network communication capabilities.

Replacement Considerations

ATSAME53J20A-AU-EFP offers identical specifications in a TQFP-64 package. ATSAMD51J20A-AUT lacks integrated Ethernet support. Verify pinout compatibility before substituting with other SAM E53 variants.
