ATSAME51N19A-AUT-EFP - 120MHz Cortex-M4F MCU 512KB | Microchip
MPN: ATSAME51N19A-AUT-EFP ✓ Hoạt độngATSAME51N19A-AUT-EFP Tóm tắt
A Cortex-M4F microcontroller (MCU) is a 32-bit microcontroller built on the ARM Cortex-M4 processor core with single-precision Floating Point Unit, designed for deterministic real-time embedded applications. It belongs to the hierarchy ARM Cortex-M -> Cortex-M4 -> Cortex-M4F MCU -> microcontroller -> semiconductor. The FPU accelerates floating-point math, while Thumb-2 instruction set keeps code density high. The SAM E51 series positions itself between Cortex-M0+ (low-power, simple) and Cortex-M7 (high-performance DSP) tiers.
Key differentiating features include the Cortex-M4F core with FPU and DSP extensions, hardware Cryptography module (AES, SHA, TRNG), 120 MHz operation, 512 KB dual-panel Flash with ECC, 192 KB SRAM, and SERCOM peripherals configurable as UART/SPI/I2C. The device supports a 1.62V to 3.6V supply and integrates a high-speed USB 2.0 Full-Speed PHY and CAN-FD controller directly on-chip.
Architecturally, the SAM E51 uses a multi-layer AHB bus matrix giving peripherals and DMA concurrent access to SRAM, eliminating contention with the CPU. The dual-panel Flash bank architecture enables live firmware updates and read-while-write, and the integrated 8-channel DMA reduces CPU load for I/O. Analog peripherals include a 12-bit 1 Msps ADC, 12-bit DAC, and analog comparators.
Typical applications include industrial automation controllers, USB peripherals (HID, CDC, audio), automotive body electronics, IoT edge nodes, and graphical HMI. The integrated CAN-FD and automotive temperature grade make it especially suitable for in-vehicle networks.
When designing with this part, provide a 1uF plus 100 nF decoupling pair within 5 mm of each VDD pin pair, and route the 12 MHz crystal traces symmetrically with grounded guard rings to meet USB full-speed jitter. The EFP reliability tier warrants a 10-year data-retention design margin.
This page consolidates distributor pricing as of 2026-09-21, drop-in same-family alternatives, and applied design notes beyond what the manufacturer datasheet alone offers, giving procurement and engineering teams a single reference for the SAM E51 selection.

Ứng dụng tiêu biểu
ATSAME51N19A-AUT-EFP phù hợp cho 6 Áp dụngs: Industrial USB-CAN Gateway, Automotive Body Control Module, USB Human Interface Device (HID) Controller, Industrial IoT Edge Sensor Node, Building Automation Controller, Portable Data Acquisition System.
Industrial USB-CAN Gateway
The ATSAME51N19A-AUT-EFP is well-suited for industrial USB-to-CAN-FD gateways bridging a host PC USB port to a CAN-FD vehicle or factory bus. The integrated USB 2.0 Full-Speed PHY eliminates an external chip, and the on-chip CAN-FD controller supports bit rates up to 5 Mbps per ISO 11898-1:2015. At 120 MHz the Cortex-M4F easily runs a full CAN-FD stack plus USB CDC class driver in under 200 KB Flash, leaving 300 KB free for application protocol translation. The automotive -40 C to +125 C grade tolerates cabinet temperatures near drives or motors.

Automotive Body Control Module
Body controllers for window lifts, mirror adjust, and lighting benefit from the ATSAME51N19A-AUT-EFP's automotive temperature range and CAN-FD integration. The Cortex-M4F FPU runs model-based body controller algorithms at low CPU load, and the 192 KB SRAM supports multiple LIN/CAN message buffers without dropping frames. The EFP Extended Flash endurance tier tolerates frequent OTA update cycles over a 10-year vehicle service life. Hardware AES and SHA accelerators secure diagnostic UDS sessions on CAN-FD.
Được đề xuất
USB Human Interface Device (HID) Controller
The integrated USB 2.0 Full-Speed PHY makes the ATSAME51N19A-AUT-EFP a single-chip solution for USB keyboards, custom input devices, and HID-class peripherals. The 32-channel DMA offloads USB endpoint servicing, allowing the 120 MHz Cortex-M4F to focus on scanning matrices and processing inputs. The 512 KB Flash accommodates USB stacks plus vendor-specific report descriptors, and the 12-bit ADC reads analog joysticks or sliders without an external MUX.
Được đề xuất
Industrial IoT Edge Sensor Node
Edge sensor nodes aggregate analog inputs from thermocouples, pressure transducers, and 4-20 mA loops and forward them over CAN-FD or USB to a gateway. The ATSAME51N19A-AUT-EFP's 12-bit 1 Msps ADC samples up to 16 channels with DMA-driven burst captures, and the Cortex-M4F DSP extensions compute RMS, FFT, and digital filters in real time. The hardware AES/SHA accelerators protect TLS-style authentication on the CAN-FD payload without burdening the CPU.
Được đề xuất
Building Automation Controller
Building automation controllers for HVAC, lighting, and access control benefit from the ATSAME51N19A-AUT-EFP's mix of USB (for commissioning laptops), CAN-FD (for backbone), and SERCOM (UART/SPI/I2C for sensors and actuators). The 192 KB SRAM holds real-time scheduling tables and BACnet/Modbus frame buffers, while the 32-channel DMA accelerates sensor polling. The -40 C to +125 C range handles rooftop equipment enclosures without derating.
Được đề xuất
Portable Data Acquisition System
Portable USB-powered data loggers use the ATSAME51N19A-AUT-EFP as the single-chip ADC + USB interface. The integrated 12-bit ADC at up to 1 Msps captures multi-channel waveforms, DMA streams them to SRAM, and the Full-Speed USB pushes them to a host PC. The 1.62 V to 3.6 V supply range supports direct Li-ion operation, and the Cortex-M4F FPU applies digital filters in firmware. The EFP endurance tier protects long-duration logging across 10-year deployments.

Ghi chú thiết kế
Provide a 1 uF X7R bulk plus 100 nF NP0/C0G high-frequency decoupling capacitor within 5 mm of each VDDIN and VDDIO pin pair. Estimated: at 120 MHz CPU clock and 3.3 V supply, the SAME51 typically draws 20-30 mA active plus peripheral transients, so the 1 uF bulk covers mid-frequency load steps while the 100 nF suppresses the clock-harmonic spurs. Star-route VDDIO from a ferrite bead if analog and digital segments coexist.
Do not confuse the -EFP (Extended Flash Performance) suffix with the -EF (Extended Filter) audio suffix. The -EFP variant is specifically for higher Flash endurance and retention, targeting OTA firmware update use cases. Also note that the -AUT suffix designates -40 C to +125 C automotive grade, while -AU is -40 C to +85 C commercial. Mixing these up can cause firmware boot failures at temperature extremes or shortened Flash lifetime.
Route the 12 MHz crystal traces (XIN/XOUT) symmetrically with matching length and grounded guard rings, and place load capacitors within 2 mm of the crystal pins. Keep the USB DP/DM traces as a 90 ohm differential pair, length-matched within 150 mils, and avoid routing near switching signals. The CAN-FD TX/RX traces should also be length-matched to maintain bit timing symmetry per ISO 11898-1:2015.
Estimated: USB Full-Speed signal integrity at 12 Mbps requires the DP/DM trace impedance to be 90 ohms differential with 45 ohms single-ended to ground. Use a 4-layer stackup with continuous ground plane beneath the USB traces, and place the 15 kohm pull-down on DM and 1.5 kohm pull-up on DP (per USB 2.0 spec) close to the connector side. Avoid vias on DP/DM if at all possible.
Thông tin tuân thủ
RoHS compliant per Microchip product page. The -AUT suffix denotes automotive temperature grade -40 C to +125 C; -EFP suffix denotes Extended Flash Performance endurance/retention. AEC-Q100 qualification status should be confirmed via Microchip factory datasheet for the specific ATSAME51N19A-AUT-EFP suffix.
