Overview
The ATSAME54N19A-AUT is a 32-bit microcontroller from the SAM E54 series, manufactured by Microchip Technology. It features an ARM Cortex-M4F core operating at a maximum frequency of 120 MHz. The device integrates 512 KB of flash memory and 96 KB of SRAM. It supports a supply voltage range of 1.62 V to 3.45 V and operates within a temperature range of -40°C to +85°C. The component is housed in a 100-pin TQFP package and includes 38 general-purpose I/O pins.
Feature Summary
- Integrated ARM Cortex-M4F processor with hardware floating-point unit for efficient signal processing
- On-chip non-volatile memory providing 512 KB flash and 96 KB RAM for code and data storage
- Comprehensive peripheral set including multiple communication interfaces and analog converters
Applications
- Industrial control systems requiring robust processing capabilities
- Smart energy metering applications
- Automotive infotainment and body electronics modules
Procurement Notes
Verify the specific suffix 'AUT' corresponds to the automotive qualification grade and tape-and-reel packaging format as defined in the official datasheet. Confirm that the 100-TQFP package dimensions match your PCB footprint requirements. Ensure compatibility with the 1.62V to 3.45V supply voltage range for your target application environment.
Selection Notes
Select this model when a balance of moderate flash capacity and high-speed processing is required in a compact 100-pin form factor. It is suitable for designs needing the ARM Cortex-M4F architecture but do not require the larger memory or I/O counts found in the P-series variants. Consider the AEC-Q100 qualification if deploying in automotive environments.
Part Context
This component belongs to the Microchip SAM E54 family, which targets secure IoT and industrial applications. The N-series variant specifically offers a mid-range configuration between the smaller M-series and the larger P-series devices, providing 512 KB of flash and 96 KB of RAM within a 100-pin TQFP package.
Replacement Considerations
ATSAME54P20A-AUT-EFP: Offers higher performance with 1 MB flash, 256 KB RAM, and 128 pins. ATSAME54N20A-AUT-EFP: Provides increased memory (1 MB flash, 256 KB RAM) while maintaining the 100-pin TQFP package.
