What are the key features of ATSAME51G18A-MUT-EFP?
- ARM Cortex-M4F core at up to 120 MHz with single-precision FPU for DSP-intensive motor control and signal processing
- 256 KB flash with hardware CAN interface for industrial automation and automotive prototype designs
- Integrated 12-bit ADC, DAC, and DMA channels enabling multi-channel data acquisition without CPU overhead
- 48-pin VQFN package with extended low-temperature operation below -20°C for harsh environment embedded systems
What is ATSAME51G18A-MUT-EFP used for?
The ATSAME51G18A-MUT-EFP is suited for industrial motor controllers, IoT gateway nodes, and fieldbus-connected embedded systems where 32-bit compute, hardware CAN, and floating-point DSP are required in a compact form factor. Its Cortex-M4F core at 120 MHz with FPU handles real-time PID loops, FFT-based sensor fusion, and CAN protocol stacks simultaneously. The VQFN-48 package and extended low-temperature rating make it a strong candidate for outdoor industrial equipment and agricultural electronics requiring operation across wide temperature ranges.

Frequently Asked Questions
What is the clock frequency and flash size of the ATSAME51G18A-MUT-EFP, and how does it compare to the SAM E51 with 512 KB flash?
The ATSAME51G18A-MUT-EFP runs at up to 120 MHz with 256 KB flash and 64 KB SRAM. The SAM E51 family also offers 512 KB flash variants for applications requiring larger firmware or data buffers. For a motor controller with CAN stack, 256 KB is typically sufficient, while the 512 KB variant suits designs with TLS/HTTPS or complex file systems.
For a real-time motor control design, how does the Cortex-M4F FPU in the ATSAME51G18A-MUT-EFP reduce PID loop latency?
The single-precision FPU executes floating-point multiply-accumulate in 1 cycle compared to 10+ cycles for software emulation on cores without FPU. For a 10 kHz PID control loop using a 12-bit ADC sample, the FPU reduces per-loop computation from roughly 50 µs to under 5 µs at 120 MHz, freeing CPU bandwidth for CAN message handling and DMA data transfers.
Does the ATSAME51G18A-MUT-EFP support CAN FD or only classic CAN, and what is its maximum CAN bit rate?
The ATSAME51G18A-MUT-EFP integrates a CAN 2.0 B compatible controller supporting classic CAN at up to 1 Mbps. It does not natively support CAN FD data phase speeds above 1 Mbps. For designs requiring CAN FD at 2 Mbps to 8 Mbps, an external CAN FD transceiver paired with a software FD controller or a different SAM series MCU with CAN FD IP would be needed.
