ATSAME51G19A-MF 概要
What is a Cortex-M4F microcontroller? An ARM Cortex-M4F microcontroller is a 32-bit embedded processor that combines a high-performance core with a single-precision Floating Point Unit (FPU), DSP extensions and tightly-coupled peripherals. It sits in the taxonomy MCU -> 32-bit MCU -> ARM Cortex-M4F MCU -> general-purpose microcontroller with FPU, and is widely used where deterministic real-time control meets numerical signal processing.
Key features include hardware cryptographic support through the TrustZone-ready SAM E51 platform, a 12-bit ADC up to 1 MSPS, multiple SERCOM serial interfaces configurable as UART/SPI/I2C, an integrated Full-Speed USB 2.0 transceiver, and an SD/MMC host controller. The 120 MHz Cortex-M4F with FPU delivers 1.25 DMIPS/MHz while retaining low-power sleep modes down to single-digit microampere quiescent current.
The ATSAME51G19A-MF leverages a Harvard-bus architecture with separate I/D buses, a multi-layer AHB matrix and tightly-coupled SRAM banks to avoid flash wait states on hot code paths. ECC on flash and SRAM provides single-bit error correction and double-bit error detection, important for industrial safety and field-reliability standards. The integrated Peripheral Touch Controller (PTC) and 6-pin configurable SERCOM set accelerate HMI and connectivity designs.
Typical applications include industrial control and automation systems, USB-connected human-interface devices, automotive body and infotainment subsystems, IoT edge nodes, and motor-control boards where the FPU accelerates real-time field-oriented control algorithms. The CAN-FD peripheral also makes the part attractive for industrial bus and medical device networking.
When designing with this MCU, allocate decoupling close to every VDD pin, follow the 48-pin QFN thermal pad soldering guidance, and use the MPLAB Harmony v3 framework for peripheral configuration to reduce firmware bring-up time. The '-MF' suffix denotes the 48-pin QFN industrial temperature grade (-40 C to +125 C) packaged on trays.

USB-Connected HMI Devices
The integrated Full-Speed USB 2.0 transceiver eliminates external PHY chips, allowing the ATSAME51G19A-MF to enumerate as a HID, CDC or vendor-class device at low BOM cost. The 48-pin QFN exposes up to 6 SERCOM channels to drive display panels, capacitive touch via the PTC controller and external serial peripherals simultaneously, while 512 KB flash accommodates USB CDC stacks plus GUI assets. The Cortex-M4F DSP extensions accelerate UI animations and smoothing filters.
おすすめ
Automotive Body and Infotainment Subsystems
CAN-FD and high ESD tolerance make the ATSAME51G19A-MF a fit for body control modules, HVAC panels and ancillary infotainment nodes where -40 to +125 C operation and reliable CAN communication are required. The FPU accelerates audio DSP for hands-free and chime generation, while 192 KB SRAM stores voice prompts and decode buffers. For full AEC-Q100 compliance a Q-grade suffix part from the same family should be selected where mandated by the OEM.
おすすめ
IoT Edge and Sensor Hubs
The ATSAME51G19A-MF aggregates data from multiple analog and digital sensors, running light local analytics on the Cortex-M4F before forwarding over USB or serial links to a gateway. TrustZone-M isolates the cryptographic key store from the application logic, while 192 KB SRAM buffers sensor packets during network outages. Low-power sleep modes drop quiescent current to single-digit microamps, making battery-powered sensor hubs feasible on a single cell.
おすすめ
Motor Control and FOC Drives
The Cortex-M4F DSP instructions and FPU compute Park/Clarke transforms and SVM modulators in real time for brushless DC and PMSM drives up to several kW. Hardware AES is used for parameter-locked firmware, and the 12-bit ADC sampled simultaneously with PWM timers provides cycle-accurate feedback. The 48-pin QFN thermal pad supports continuous switching losses at industrial duty cycles without derating below 1A load drive.
おすすめ
Medical Monitoring Devices
The ATSAME51G19A-MF's hardware cryptography and ECC memory protection support IEC 62304 and FDA cybersecurity premarket guidance for connected medical devices. The FPU accelerates ECG/EEG DSP filters, 192 KB SRAM holds multi-channel sample buffers, and USB 2.0 enumerates as a USB CDC medical-class device for host software integration. The wide 1.62-3.63 V supply rail simplifies designs powered from single-cell Li-ion with direct battery monitoring.

主な差別化要因
- On-chip CAN-FD plus Full-Speed USB on a 48-pin Cortex-M4F MCU （vs ATSAMD51G19A-MF)
- Cortex-M4F with FPU at 120 MHz and 512 KB flash in 48-QFN （vs ATSAMD21G18A-MF)
- Drop-in-compatible with ATSAME51G18A-MF in identical QFN （vs NXP MK22FN512)
設計ノート
Estimated: 48-pin QFN package requires a continuous exposed thermal pad soldered to a copper pour of at least 25 mm^2 for adequate thermal dissipation. Place 0.1 uF decoupling capacitors within 3 mm of every VDDIO and VDDCORE pin, and add a 10 uF bulk capacitor near the USB supply pins. QFN routing demands via-in-pad or dog-bone fanouts on inner layers to break out inner-row pads without violating design rules.
The ATSAME51G19A-MF integrates dual voltage regulators (LDO and DC-DC buck) selectable via the VREGSEL fuse; misconfiguring this for a 1.8 V system can leave the core under-supplied. Confirm the fuse setting before programming, and review the SAM E51 errata for rev-A silicon differences. The USB bus requires a 1 uF bypass on VBUS sense for hot-plug reliability.
Estimated: At maximum 120 MHz and 3.6 V supply with sustained GPIO toggling, the ATSAME51G19A-MF draws roughly 80 mA active current. With the 48-QFN theta_JA of ~33 C/W on a 4-layer JEDEC test board, the junction rises ~2.6 C/W per watt dissipated. For continuous motor-control or USB workloads, design the PCB copper pour to keep junction below 100 C ambient.
