ATSAME54P19A-AU-EFP

Overview

The ATSAME54P19A-AU-EFP is a 32-bit microcontroller from the Microchip SAM E54 series, featuring an ARM Cortex-M4F core with a floating-point unit. It operates at a maximum frequency of 120 MHz and includes 512 kB of flash memory and 192 kB of SRAM. The device provides 99 general-purpose I/Os and supports multiple communication interfaces including CANbus, Ethernet, I2C, SPI, UART/USART, and USB. It is housed in a 128-TQFP package and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

Integrated floating-point unit within the ARM Cortex-M4F core for enhanced mathematical processing capabilities.
Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
Comprehensive connectivity suite supporting CANbus, Ethernet, LINbus, and various serial protocols.

Applications

Automotive body control modules
In-vehicle infotainment systems
Industrial motor control applications

Procurement Notes

Verify the specific suffix 'EFP' against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the AEC-Q100 qualification status aligns with your project's automotive reliability requirements before finalizing procurement.

Selection Notes

Select this component when a robust automotive-grade MCU with high-speed Ethernet and CAN connectivity is required. The combination of 512 kB flash and 192 kB RAM suits complex control algorithms, while the 120 MHz performance balances processing power with power efficiency constraints.

Part Context

This part belongs to the SAM E54 family, designed for automotive and industrial markets. It shares architectural similarities with other SAM E5x devices but offers specific memory and pin configurations tailored for mid-range control applications requiring extensive peripheral support.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified alternatives within the SAM E54 or SAM E53 families. Ensure any substitute maintains AEC-Q100 qualification and compatible pinout if direct replacement is necessary.
