ATSAME53J19A-AU-EFP

Overview

The ATSAME53J19A-AU-EFP is an ARM Cortex-M4F microcontroller in the SAM E53 family, housed in a 64-pin TQFP package. It features 512 kB of Flash memory and 192 kB of SRAM. The device operates at a maximum clock frequency of 120 MHz with a supply voltage range of 1.71 V to 3.63 V. It includes 24-channel 12-bit ADCs, two 12-bit DACs, and supports interfaces such as Ethernet, USB, SPI, I2C, USART, LIN, QSPI, and I2S. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Integrated floating-point unit (FPU) within the ARM Cortex-M4F core for efficient mathematical processing.
• Supports high-speed communication via integrated Ethernet MAC and USB OTG controllers.
• Features extended flash performance capabilities for enhanced code execution speed.
• Includes multiple timer/counters and DMA channels for complex peripheral management.

Applications

• Industrial automation systems requiring robust connectivity and processing power.
• Smart home devices utilizing Ethernet and wireless integration.
• Medical equipment needing precise analog signal acquisition via high-resolution ADCs.
• Consumer electronics with display interfaces and user input requirements.

Procurement Notes

Verify the specific suffix 'EFP' corresponds to the tray packaging format when ordering, as other suffixes like 'T' indicate tape and reel. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure design-in compatibility with the 64-TQFP footprint and verify that the 1.71V to 3.63V operating voltage aligns with target system power rails.

Selection Notes

Select this model over variants with different memory sizes based on specific application storage needs, as it provides 512 kB Flash and 192 kB RAM. Consider the TQFP-64 package if surface-mount assembly with standard footprints is required rather than BGA options. Evaluate the need for the integrated FPU and Ethernet controller against simpler Cortex-M4 parts without these peripherals to optimize cost and pin count.

Part Context

This component belongs to the Microchip SAM E53 series, designed for applications demanding high performance and rich connectivity. The series integrates ARM Cortex-M4F cores with advanced security features and extensive peripheral sets. It targets markets including industrial, consumer, and IoT where reliable data processing and network communication are critical.

Replacement Considerations

Direct substitutes within the same package and pinout include ATSAME53J20A-AU-EFP (1 MB Flash) or ATSAME53J18A-AU (256 KB Flash). Verify functional equivalence regarding memory size and peripheral availability before substitution.
