ATSAME70N20A-AN - 300MHz Cortex-M7 MCU, 1MB Flash, LQFP-100
MPN: ATSAME70N20A-AN ✓ AktifATSAME70N20A-AN Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals such as timers, ADCs, communication interfaces, and GPIO into one package. The Cortex-M7 architecture sits at the top of the ARM Cortex-M family hierarchy (Cortex-M0 -> M3 -> M4 -> M7) and is the highest-performance tier targeting deterministic real-time DSP and floating-point workloads. The ATSAME70N20A-AN therefore spans the use cases previously reserved for separate DSP or external-FPGA coprocessors while remaining a microcontroller-class device with deterministic interrupt response.
Key features include a 16-bit stereo interface, high-speed USB Host/Device with on-chip HS PHY, two CAN-FD controllers, Ethernet MAC with 1588 PTP support, an image sensor interface, an 8/12-bit Parallel Capture, and a 12-bit 2 MSPS ADC. Cryptographic accelerators (AES-256, SHA, TRNG) and secure-boot with on-chip OTP fuse make the part suitable for connected industrial and IoT security deployments. The integrated High-Speed USB PHY eliminates external transceivers, reducing BOM and PCB area for USB-equipped designs.
The device supports 1.8 V, 2.5 V, and 3.3 V I/O domains, simplifying connection to mixed-voltage sensors, FPGAs, and external memory. A 16-channel Event System, 24-bit timers, and a Quad-SPI interface with XIP (execute-in-place) enable deterministic real-time response and easy expansion of code storage beyond the on-chip 1 MB Flash. Operating temperature spans -40 C to +105 C for industrial environments.
Typical applications include industrial motor control (FOC and PFC), graphical HMI, audio DSP, automotive body and gateway ECUs, smart-energy metering, and connected IoT edge nodes with Ethernet or USB connectivity. The combination of 300 MHz Cortex-M7, FPU, and DSP extensions delivers DSP-class signal-processing throughput on a single MCU.
When designing with this device, plan for an LQFP-100 footprint with a central thermal pad, route the 16-bit data bus and SDRAM signals with controlled impedance, and place decoupling capacitors within 2 mm of every supply pin. Refer to the SAME70 family datasheet for SDRAM timing and the recommended USB and Ethernet magnetics layout.

Aplikasi Umum
ATSAME70N20A-AN cocok untuk 8 aplikasis: Industrial Motor Control (FOC / PFC), Graphical HMI Touch Panels, Connected Industrial IoT Edge Nodes, Audio Processing and USB Audio Devices, Automotive Body and Gateway ECUs, Smart Energy Metering, Industrial Machine Vision, Robotics and Drone Flight Controllers.
Industrial Motor Control (FOC / PFC)
The ATSAME70N20A-AN is purpose-built for industrial motor control. Its Cortex-M7 core with single- and double-precision FPU executes field-oriented control (FOC) loops at 300 MHz, easily handling 20 kHz PWM with sub-microsecond jitter. The on-chip 12-bit 2 MSPS ADC captures three-phase current and DC-bus voltage simultaneously, while the hardware sine/cosine math accelerator delivers vector rotations without CPU load.

Graphical HMI Touch Panels
The 300 MHz Cortex-M7 plus 384 KB SRAM drives WVGA TFT-LCD displays using the integrated LCD controller with overlay and color palette. Combined with external SDRAM via the 16-bit EBI, designers can render anti-aliased fonts, animations, and image icons smoothly. The image sensor interface (ISI) supports camera input for industrial HMI cameras, while the capacitive touch library uses the event channel for low-latency input.
Direkomendasikan
Connected Industrial IoT Edge Nodes
The ATSAME70N20A-AN is engineered for Ethernet- and USB-connected industrial edge nodes. The 10/100 MAC with IEEE 1588 PTP hardware timestamping enables sub-microsecond synchronization for deterministic Ethernet (TSN-ready) deployments, while the two CAN-FD controllers support modern automotive and industrial CAN networks. AES-256 and SHA hardware acceleration secures OTA firmware updates and TLS tunnels without taxing the CPU.
Direkomendasikan
Audio Processing and USB Audio Devices
The integrated 16-bit stereo audio interface plus USB 2.0 High-Speed device mode make the ATSAME70N20A-AN ideal for USB audio DACs, headsets, and professional audio equipment. The Cortex-M7 FPU executes biquad filters, dynamics processing, and ASIO drivers in real time, while the on-chip HS USB PHY streams 192 kHz/24-bit audio directly to a host PC with deterministic latency.
Direkomendasikan
Automotive Body and Gateway ECUs
ATSAME70N20A-AN is suitable for non-safety body and gateway ECUs where the Cortex-M7 handles CAN-FD aggregation, LIN coordination, and Ethernet backhaul. Two CAN-FD controllers multiplex multiple legacy CAN buses, while Ethernet MAC bridges them to a central gateway. The -40 C to +105 C industrial temperature range covers most cabin and underhood locations, though safety-critical domains should move to ATSAMS70N20A-AN instead.
Direkomendasikan
Smart Energy Metering
The high-performance Cortex-M7 plus 12-bit 2 MSPS ADC make the ATSAME70N20A-AN ideal for smart electricity meters, performing real-time Class 0.2 metering calculations, RMS measurement, and harmonic analysis. The hardware crypto block secures DLMS/COSEM communications over Ethernet or PLC links, and the RTC with calendar supports tariff scheduling and time-of-use billing without external RTC chips.
Direkomendasikan
Industrial Machine Vision
The integrated image sensor interface (ISI) of the ATSAME70N20A-AN streams camera input up to 720p/30 fps into SDRAM, while the Cortex-M7 runs pre-processing, blob detection, and barcode recognition in real time. Combined with the Ethernet MAC, this enables compact industrial inspection cameras for assembly line QC that do not require an external processor or DSP.
Direkomendasikan
Robotics and Drone Flight Controllers
The 300 MHz Cortex-M7 with double-precision FPU runs quaternion-based flight math and PID loops at kHz rates for multirotor flight controllers. High-speed USB, dual CAN-FD, and Quad-SPI peripheral expansion support ESC telemetry, GPS modules, and radio links. The SAME70 family is widely adopted in open-source flight stacks such as PX4-compatible autopilots, making ATSAME70N20A-AN a drop-in upgrade path.

Catatan Desain
Estimated: at 300 MHz with all peripherals active, core current is approximately 150 mA from VDDCORE plus 30 mA distributed across VDDIO banks. Use a 3.3 V LDO with at least 500 mA headroom and place 100 nF + 4.7 uF decoupling within 2 mm of every VDDIO/VDDCORE pin. Add a ferrite bead between analog and digital VDDIO if the 12-bit ADC is in use.
Route the 16-bit EBI bus to external SDRAM with controlled impedance (50 ohm single-ended) and length-match within 50 mils. Keep SDRAM traces short, use 22 ohm series damping, and place a ground guard ring around the clock pair to maintain signal integrity at 100 MHz SDRAM clock. The QSPI traces to boot flash should also be length-matched within 10 mil.
The LQFP-100 thermal pad is not present, so thermal dissipation relies entirely on the lead frame. For high ambient temperature (>85 C) designs running sustained Cortex-M7 at 300 MHz, ensure PCB copper area of at least 4 square inches around the device. Failure to disable unused peripherals in software increases VDDIO draw by up to 30 mA.
USB 2.0 High-Speed requires 90 ohm differential impedance on the DP/DN pair. Route DP/DN with continuous reference plane on layer 2, no splits or via stubs, and place the ESD protection diode within 3 mm of the connector. Per USB-IF compliance, keep the total DP/DN length under 50 mm for the on-chip HS PHY.
