ATSAME70N19A-ANT 개요
An ARM Cortex-M7 microcontroller belongs to the high-performance microcontroller category, which sits within the broader taxonomy of embedded processors -> microcontrollers -> 32-bit MCUs -> ARM Cortex-M family -> Cortex-M7 sub-family. Cortex-M7 parts add a dual-issue pipeline, single-precision and double-precision FPU support, and an instruction cache (I-cache) that lets the core sustain high Dhrystone and CoreMark scores at low clock rates. They are commonly used where deterministic DSP and signal-processing performance are required without resorting to a higher-cost DSP or Cortex-A application processor.
Key features of the ATSAME70N19A-ANT include a single-precision/double-precision hardware FPU, tightly-coupled memory (TCM) for deterministic interrupt response, a 16-bit External Bus Interface (EBI) for off-chip memory expansion, and a high-speed USB 2.0 Full-Speed device/host with on-chip PHY. Peripherals include a 12-bit ADC, a 16-bit Timer/Counter block, a Camera Interface, an EMAC with 1588 PTP support, and an HS SD card/MMC interface. The device operates from a 1.62V to 3.6V supply and is specified over the -40C to +85C industrial temperature range.
Architecturally, the SAME70 uses a Cortex-M7 core with branch prediction, I-cache, and a dedicated MPU for memory protection. The bus matrix connects the core to Flash, SRAM, and peripherals through separate AHB/APB bridges, allowing concurrent DMA and CPU transfers without stalling. The on-chip voltage regulator simplifies single-rail 3.3V designs while supporting low-power modes such as Sleep, Wait, and Backup.
Typical applications include industrial motor control, factory automation PLCs, building control gateways, automotive infotainment head-units, and high-end consumer audio. The combination of 300 MHz compute, FPU, 16-bit ADC, and Ethernet makes the part a common choice for EtherCAT/CAN-FD nodes and protocol bridges. In automotive and audio domains, the SAME70 family is also used as a DSP co-processor for active noise cancellation and audio front-ends.
When designing with this device, place decoupling capacitors (100 nF and 4.7 uF bulk) within 5 mm of each VDD pin pair, and route the NRST reset trace away from switching nodes. Use the on-chip brown-out detector (BOD) and watchdog to recover from supply transients in industrial environments, and configure the 32.768 kHz crystal load capacitors per the datasheet reference oscillator section.

일반적인 애플리케이션
ATSAME70N19A-ANT 적합 용도: 6 애플리케이션s: Industrial Motor Control (FOC / Servo Drive), Industrial Ethernet Gateway / PLC, Automotive Infotainment Head-Unit / Audio Hub, Building Automation Controller (BACnet / KNX), Industrial HMI / TFT Display Controller, Portable Medical Diagnostic Device.
Industrial Motor Control (FOC / Servo Drive)
The ATSAME70N19A-ANT's 300 MHz Cortex-M7 with single/double-precision FPU accelerates Park/Clarke transforms and space-vector modulation in field-oriented control (FOC) firmware, achieving torque-loop update rates well under 10 us. Its 12-bit 1 MSPS ADC paired with dedicated PWM timer/counter blocks supports 3-phase sinusoidal commutation for brushless DC and permanent-magnet synchronous motors (PMSM). The same chip's tightly-coupled memory keeps interrupt latency deterministic under DMA pressure, which is essential for safety-critical servo drives requiring IEC 61800-5-2 compliance. The integrated CAN-FD interface enables multi-axis coordination on industrial field-bus networks.
추천
Industrial Ethernet Gateway / PLC
With integrated 10/100 Ethernet MAC supporting IEEE 1588 PTP and CAN-FD controllers, the ATSAME70N19A-ANT serves as the main controller in PLC and protocol-bridge gateways that translate between EtherCAT, PROFINET, and CANopen networks. The 300 MHz Cortex-M7 runs a full TCP/IP stack alongside application firmware without dropping frames, while 256 KB SRAM accommodates TLS handshake buffers and Modbus TCP buffers. The 16-bit External Bus Interface (EBI) lets designers attach parallel SRAM or NOR Flash for logging, useful in industrial data-acquisition nodes. The on-chip 12-bit ADC reads analog sensor inputs directly.
추천
Automotive Infotainment Head-Unit / Audio Hub
The SAME70 family is widely deployed in automotive infotainment head-units and audio hubs where the Cortex-M7's DSP extensions (SIMD instructions) and FPU handle audio decode, sample-rate conversion, and ANC algorithms in real time. The integrated I2S and HS-SD/MMC interfaces connect directly to external audio codecs and SD-card media, while the EMAC streams network audio via AVB/TSN. The 300 MHz headroom allows concurrent Bluetooth handoff, voice-prompt mixing, and Class-D amplifier feedback loops on a single MCU. The 14x14 LQFP-100 package is friendly to multi-layer automotive PCBs with controlled-impedance routing.
추천
Building Automation Controller (BACnet / KNX)
The ATSAME70N19A-ANT's mix of Ethernet, USB, CAN, and UART interfaces makes it a natural fit for building-automation controllers that bridge BACnet/IP, KNX, Modbus, and proprietary HVAC buses. The Cortex-M7 core runs a full BACnet stack while leaving cycles free for control-loop math, and the 256 KB SRAM supports TLS session caches for cloud-connected BMS nodes. RTC with calendar mode and Backup domain keep time during power events, while the on-chip 12-bit ADC monitors temperature/humidity sensors directly. The wide 1.62-3.6V supply tolerates 24V industrial bus rails after regulation.
추천
Industrial HMI / TFT Display Controller
The 300 MHz Cortex-M7 plus integrated 2D graphics support and parallel EBI drive small-to-medium TFT displays (up to 480x272) for industrial HMI panels without an external graphics controller. The HS-SD/MMC interface loads graphical assets directly from SD cards at boot, while the EMAC delivers remote firmware updates. The 12-bit ADC reads touch-screen coordinates when paired with a resistive overlay, and the multiple SPI/I2C instances drive external RTCs and EEPROMs. Designers benefit from SAME70's mature ASF (Atmel Software Framework) drivers that shorten HMI development cycles.
추천
Portable Medical Diagnostic Device
The ATSAME70N19A-ANT suits portable medical diagnostic devices such as glucose meters, pulse-oximeters, and handheld ECG monitors where deterministic real-time response and low-power Sleep modes matter. The 12-bit 1 MSPS ADC samples biopotential signals at sufficient fidelity for screening-grade measurements, while the FPU accelerates digital filtering (IIR/FIR) and FFT analysis for heart-rate variability. The Backup domain with RTC maintains accurate timekeeping across battery swaps, and the wide supply range (1.62-3.6V) supports direct Li-ion battery operation. The 100-LQFP footprint is hand-solder-friendly for low-volume clinical device builds.

설계 노트
Place one 100 nF decoupling capacitor within 3 mm of each VDDIO pin and a 4.7 uF bulk capacitor on each VDDCORE pin pair. Estimated: at 300 MHz core and typical 80 mA active current, a single 4.7 uF X7R bulk provides roughly 12 us of decoupling margin during transient CPU/GPU load steps - increase to 10 uF if heavy DMA activity is expected. Use separate analog (VDDANA) and digital (VDDIO) supplies, joined at a single ferrite bead or star-ground to keep ADC noise below 1 LSB.
Route the 32.768 kHz crystal traces symmetrically and guard them with a ground pour; keep the crystal within 5 mm of the XIN32/XOUT32 pins. Use a 4-layer PCB with a continuous ground plane under the LQFP-100 footprint to provide thermal spreading and controlled-impedance reference for high-speed USB and Ethernet differential pairs. Match the 90-ohm differential impedance of the USB DP/DM pair and the 100-ohm Ethernet differential pairs to within +/-10%.
Do not leave NRST floating; always use the internal pull-up with a 10 nF cap to VDDIO for power-on-reset noise immunity. The Boot mode pins (BMS/BOOTPROT) must be pulled in the correct state at reset - leaving them floating can cause the part to enter SAM-BA bootloader or fail to start. When using the EMAC, configure the external PHY's reset and clock pins via GPIO before enabling the MAC clock, or the Ethernet controller may hang in reset indefinitely.
