Overview
The ATSAME51J20A-MF is a 32-bit ARM Cortex-M4F microcontroller from the Microchip SAM E51 family, housed in a VQFN-64 package. It features a maximum clock frequency of 120 MHz, 1 MB of Flash program memory, and 256 kB of SRAM data RAM. The device includes a 12-bit ADC with 24 channels and a 12-bit DAC. It operates within a supply voltage range of 1.71 V to 3.6 V and supports an extended industrial temperature range from -40°C to +125°C. Key interfaces include I2C, LIN, SPI, USART, and USB.
Feature Summary
- Integrated ARM Cortex-M4F core with floating-point unit for efficient digital signal processing
- Extended temperature operation capability suitable for harsh industrial environments
- Built-in capacitive touch sensing peripheral (PTC) supporting keys and sliders
- Comprehensive connectivity suite including USB Full-Speed and multiple serial communication protocols
Applications
- Industrial automation controllers requiring robust environmental tolerance
- Smart home devices utilizing integrated capacitive touch interfaces
- Portable battery-powered equipment benefiting from low-voltage operation
- Automotive infotainment or instrument clusters meeting AEC-Q100 standards
Procurement Notes
Verify the specific suffix 'MF' confirms the VQFN-64 package and extended temperature grade (-40°C to +125°C). Ensure compatibility with existing PCB footprints for the VQFN-64 form factor. Confirm that the selected revision matches the required firmware compatibility level for the SAM E51 series peripherals.
Selection Notes
Select this component when an ARM Cortex-M4F MCU is needed with high non-volatile memory capacity in a compact surface-mount package. It is appropriate for designs requiring extended temperature stability beyond standard commercial limits. Consider the availability of QTouch libraries if capacitive user interfaces are part of the system architecture.
Part Context
This part belongs to the SAM E51 family, which targets cost-sensitive applications requiring advanced connectivity and touch capabilities. It shares architectural similarities with the ATSAMD51 series but offers optimized peripheral sets for IoT and industrial control. The device integrates hardware security features alongside its processing power.
Replacement Considerations
ATSAME51J20A-AU: Same core and memory but in TQFP-64 package with limited temperature range. ATSAMD51J20A-MF: Pin-compatible alternative without USB interface support.
