ATSAME51N19A-AUT 概要
A microcontroller (MCU) is a single-chip computer containing a processor core, program and data memory, peripheral interfaces, and often analog and digital peripherals. Within the broader semiconductor taxonomy, MCUs sit under embedded processors, which are themselves a category of microcontrollers. The Cortex-M4F architecture uses a Harvard bus topology with separate instruction and data paths, and the FPU accelerates single-precision floating-point operations needed for sensor fusion, control loops, and digital signal processing. The SAM E51 line is Microchip's high-performance extension of the SAM D5x/E5x family, adding hardware cryptography and a QSPI interface for external memory expansion.
Key features include 120 MHz core speed with single-precision FPU, 512 KB Flash with error-correcting code, 192 KB SRAM, Full-Speed and High-Speed USB 2.0 with integrated PHY, CAN-FD controllers, an Ethernet MAC with 1588 PTP support, and multiple SERCOM peripherals configurable as UART, SPI, I2C, or LIN. The device provides a 12-bit ADC up to 1 Msps, a 16-bit Sigma-Delta ADC, multiple PWM timers for motor and power-conversion control, and a Parallel Capture Controller for camera and image-sensor interfaces.
Typical applications include industrial control and HMI, building automation gateways, CAN-FD automotive body and chassis ECUs, connected appliance controllers, and low-cost audio playback/recording systems. The integrated Ethernet MAC with IEEE-1588 timestamping and the USB HS PHY make the part attractive for industrial gateways and protocol bridges.
When designing with the ATSAME51N19A-AUT, ensure adequate decoupling on VDDIO and VDDC rails (1uF + 100nF near each pin group). Programming is supported through Microchip Studio, MPLAB X IDE, and Atmel START; SWD and JTAG are exposed for hardware debug.

主な用途
ATSAME51N19A-AUT の用途: 6 件s: Industrial Control and HMI, Building Automation Gateways, CAN-FD Automotive Body and Chassis ECUs, Connected Appliance Controllers, Low-Cost Audio Playback and Recording, IoT Sensor Hubs and Edge Nodes.
Industrial Control and HMI
The ATSAME51N19A-AUT is well-suited for industrial control and Human-Machine Interface (HMI) applications where deterministic real-time response and rich connectivity are required. The 120 MHz Cortex-M4F core plus FPU accelerates HMI rendering pipelines, multi-state machine control, and floating-point sensor calculations within tight loop budgets. Hardware peripheral set including CAN-FD and SERCOM allows direct wiring to motor drives, PLC backplanes, and sensor hubs; Ethernet MAC with IEEE-1588 PTP supports synchronized industrial networking on the factory floor.
おすすめ
Building Automation Gateways
Building automation gateways require multiple field-bus interfaces, secure network connectivity, and reliable 24/7 operation. The ATSAME51N19A-AUT delivers Full-Speed and High-Speed USB 2.0 PHYs, an Ethernet MAC, multiple SERCOM configurable as UART or SPI, and a hardware cryptographic accelerator for TLS/AES operations. These features let the device sit between sub-gigahertz wireless or wired sensor networks and an IP backbone. Industrial-grade temperature tolerance of -40C to +85C covers unheated equipment rooms.
おすすめ
CAN-FD Automotive Body and Chassis ECUs
Although the -AUT part suffix marks industrial-grade rather than automotive-grade qualification, the ATSAME51N19A-AUT's dual CAN-FD controllers and hardware cryptographic accelerator make it suitable for body and chassis control modules outside the strictest AEC-Q100 requirements. The 120 MHz Cortex-M4F provides headroom for CANopen or J1939 protocol stacks, while the 12-bit ADC captures sensor inputs. Designers targeting true automotive qualification should upgrade to AEC-Q100 qualified variants in the same family.
おすすめ
Connected Appliance Controllers
Consumer and commercial appliance controllers increasingly need Wi-Fi, BLE, or cloud-connectivity integration. The ATSAME51N19A-AUT supplies a Cortex-M4F with FPU for control loops plus USB 2.0 HS PHY and Ethernet MAC for wired cloud uplink, while offloading BLE/Wi-Fi to companion modules via SERCOM (SPI/UART). Hardware AES support encrypts local data; the integrated TRNG feeds secure key generation for TLS handshakes.
おすすめ
Low-Cost Audio Playback and Recording
Audio subsystems using I2S peripherals benefit from the ATSAME51N19A-AUT's Cortex-M4F DSP capabilities and DMA-driven peripherals. The device can drive an external audio codec via I2S, performing sample-rate conversion and basic equalization in firmware. While dedicated audio DSPs offer more MIPS, the SAM E51 is competitive where the BOM cost budget is tight and a single part must handle both audio processing and user-interface or connectivity tasks.
おすすめ
IoT Sensor Hubs and Edge Nodes
Edge computing sensor hubs aggregate multiple sensor types and run lightweight inference or filtering before forwarding. The ATSAME51N19A-AUT combines a 120 MHz Cortex-M4F with FPU for on-device filtering, a 12-bit ADC at 1 Msps for high-speed analog frontends, and a low-power sleep mode for battery-friendly operation. Multiple SERCOM blocks connect to digital sensors via SPI or I2C, while Ethernet and USB serve as primary host links for deterministic industrial sensor nodes.

設計ノート
Provide separate decoupling for VDDC (1.62 V core) and VDDIO (3.3 V I/O) rails. Place a 1uF X7R ceramic plus a 100 nF X7R ceramic within 5 mm of each pin-group VDDC/VSS pair. A bulk 4.7 uF to 10 uF ceramic on the main VDDIO rail is recommended when USB HS transients occur. Estimated: at 120 MHz active with full peripheral clocking, expect approximately 50-60 mA peak current draw on VDDC. Use a series ferrite bead if routing shared power between MCU and other 3.3 V devices.
Maintain a solid VSS plane beneath the 100-pin TQFP and stitch it to the thermal pad of any analog AGND references. Route USB DP/DM lines as a 90 ohm differential pair of equal length within a few mm of the on-chip PHY; keep them away from switching regulators. The Ethernet MAC TX/RX pairs to an external PHY should match 50 ohm single-ended or 100 ohm differential impedance and be length-matched. Place the crystal within 5 mm of the XTAL pins to avoid stray capacitance.
Do not leave unused SERCOM pins floating in input-enabled mode; configure unused pins as output-low or enable the internal pull-down to avoid spurious interrupts. The internal DFLL requires careful CONFIG tuning - refer to the Microchip errata document for the latest silicon revision. Estimated: a typical firmware-booted Cortex-M4F idle current is in the microamp range if you sleep with RTC running, but improperly configured peripherals can keep IDLE current above 10 mA; verify with a multimeter before assuming battery-friendly operation.
コンプライアンス情報
RoHS compliant per Microchip product information. The -AUT suffix marks industrial temperature grade; this is not equivalent to AEC-Q100 automotive qualification - for AEC-Q100 applications consult Microchip's automotive-grade SAM family.
