ATSAME53J20A-AU-EFP

Overview

The ATSAME53J20A-AU-EFP is a 32-bit ARM Cortex-M4F microcontroller from the Microchip SAM E53 family, housed in a TQFP-64 package. It features 1 MB of Flash memory and 256 kB of SRAM. The device operates at a maximum clock frequency of 120 MHz with an I/O voltage of 3.3 V. Power supply ranges from 1.71 V to 3.63 V, supporting operation between -40°C and +85°C. It includes 51 I/O pins, 24 ADC channels (12-bit), 2 DAC channels (12-bit), and six timers. Interfaces include Ethernet, USB, SPI, I2C, USART, LIN, QSPI, and I2S.

Feature Summary

• Integrated Ethernet MAC controller for network connectivity
• Floating-point unit (FPU) support within the ARM Cortex-M4F core
• High-resolution analog-to-digital conversion with 24 input channels
• Dual digital-to-analog converters for signal generation

Applications

• Industrial automation controllers requiring Ethernet communication
• Smart home hubs with USB peripheral connectivity
• Medical devices utilizing high-precision analog sensing
• Automotive infotainment systems operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'AU' confirms the TQFP-64 tray packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 1.71 V to 3.63 V operating voltage range. Check for any recent product change notifications regarding assembly sites or material composition updates.

Selection Notes

Select this component when both Ethernet connectivity and USB host/device capabilities are required on a single chip. The 1 MB Flash size supports complex firmware applications without external memory. The 64-pin form factor offers a balance between pin count and board space constraints compared to larger packages in the same series.

Part Context

This part belongs to the SAM E53 series, designed for applications needing robust connectivity and processing power. It shares the Cortex-M4F core architecture with other members but differs in memory size and package options. The J20 designation typically indicates the 1 MB Flash and 256 kB RAM configuration within the 64-pin footprint.

Replacement Considerations

ATSAMD51J20A-AU-EFP: Similar memory and core but lacks integrated Ethernet MAC. ATSAME53J20A-AUT-EFP: Identical electrical specifications but supplied in tape-and-reel packaging instead of trays.
