Overview
The ATSAME51J18A-MUT is a 32-bit microcontroller from the Microchip SAM E51 series, built on the ARM Cortex-M4F core with an integrated FPU. It operates at a maximum frequency of 120 MHz and includes 256 KB of Flash memory and 128 KB of SRAM. The device features 24 channels of 12-bit ADCs and two 12-bit DACs. It supports interfaces including CAN, LIN, I2C, SPI, USART, and USB Full Speed. Operating voltage ranges from 1.71 V to 3.6 V, with an industrial temperature range of -40°C to +85°C. It is housed in a 64-pin QFN package.
Feature Summary
- Integrated ARM Cortex-M4F processor with hardware floating-point unit for efficient signal processing.
- Comprehensive analog subsystem featuring multiple 12-bit ADCs and precision DACs.
- Robust connectivity suite supporting CAN, LINbus, Ethernet MAC, and USB Full Speed.
- Advanced security features including secure boot and cryptographic accelerators.
Applications
- Industrial automation controllers requiring robust communication protocols.
- Smart energy metering systems utilizing precise analog measurement capabilities.
- Medical devices needing high-performance processing and low power consumption.
- Consumer electronics integrating touch interfaces and display drivers.
Procurement Notes
Verify the specific suffix 'MUT' corresponds to the tape and reel packaging configuration when ordering. Confirm that the required operating temperature range aligns with the industrial grade specification. Ensure design compatibility with the 64-pin QFN footprint dimensions. Check for any recent Product Change Notifications regarding pinout or electrical characteristics updates from the manufacturer.
Selection Notes
Select this component when a balance of processing power and peripheral richness is required within a compact form factor. It is suitable for applications demanding CAN/LIN bus connectivity alongside high-speed USB interfaces. Consider alternative packages if surface area constraints differ from the QFN-64 layout. Evaluate power supply requirements against the specified 1.71V to 3.6V operational window.
Part Context
This part belongs to the SAM E51 family, designed for cost-sensitive applications requiring high performance. It shares architectural similarities with the SAM D51 but adds enhanced connectivity options like Ethernet MAC. The family targets markets such as smart meters, industrial IoT, and medical equipment where reliability and feature density are critical.
Replacement Considerations
ATSAMD51J18A-MUT offers similar core specifications but lacks the Ethernet MAC interface found in the ATSAME51 variant. ATSAME51J18A-MU provides identical functionality in a tray package instead of tape and reel. Cross-referencing with the ATSAME53 series may provide additional flash capacity but requires verification of pin compatibility.
