ATSAME53J20A-AUT-EFP

Overview

The ATSAME53J20A-AUT-EFP is a 32-bit microcontroller based on the ARM Cortex-M4F core, operating at a maximum frequency of 120MHz. It features 1MB of in-system programmable flash memory and 256KB of SRAM. The device includes an integrated floating-point unit (FPU) and supports a supply voltage range of 1.71V to 3.63V. Connectivity options include Ethernet, USB, I2C, SPI, USART, QSPI, LINbus, I2S, IrDA, and MMC/SD interfaces. It offers 81 general-purpose I/Os and is housed in a 64-TQFP package with an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated Ethernet MAC with dedicated DMA for high-speed network communication
• Hardware floating-point unit (FPU) for efficient mathematical processing
• Multiple peripheral interface controllers including USB OTG and QSPI for external memory access
• Advanced analog peripherals with multiple 12-bit ADC channels and DAC outputs

Applications

• Industrial automation controllers requiring robust connectivity
• Smart home hubs and IoT gateways with Ethernet and wireless capabilities
• Medical devices needing precise analog signal acquisition
• Automotive infotainment systems within extended temperature ranges

Procurement Notes

Verify the specific suffix 'AUT' indicates automotive qualification status against the official Microchip datasheet. Confirm the package type is 64-TQFP as listed in distributor catalogs. Check for any recent Product Change Notifications (PCN) regarding assembly sites or materials. Ensure compatibility with your board's thermal management requirements for the TQFP form factor.

Selection Notes

Select this component when both Ethernet connectivity and significant code storage are required. Compare RAM sizes with other SAM E53 variants if data buffering needs exceed 256KB. Consider the pin count of the 64-TQFP package against your I/O requirements. Verify that the 120MHz clock speed meets your real-time processing constraints without excessive power consumption.

Part Context

This part belongs to the Microchip SAM E53 family, designed for applications demanding high performance and rich connectivity. It shares architectural similarities with the ATSAMD51 series but adds Ethernet capabilities. The 'AUT' suffix typically denotes automotive-grade reliability standards, distinguishing it from commercial variants like the AU suffix.

Replacement Considerations

ATSAME53J20A-AU-EFP is a commercial grade alternative with identical electrical specifications but potentially different environmental qualifications. ATSAME53N20A-AUT-EFP offers similar performance but lacks the Ethernet controller found in the J-series.
