ATSAMS70Q21B-ANT 概要
What is a Cortex-M7 microcontroller? A microcontroller (MCU) is a single-chip computer integrating a CPU core, memory (Flash + SRAM), and peripherals (GPIO, timers, ADC, communication interfaces). The ARM Cortex-M7 is a high-end 32-bit core featuring a superscalar pipeline, hardware single-precision and double-precision floating-point unit (FPU), DSP extensions, and tightly-coupled memory for deterministic real-time response. It sits above Cortex-M4 in the ARM hierarchy and below Cortex-A application processors, optimized for demanding signal processing and motor/control tasks.
Key features of the ATSAMS70Q21B-ANT include: ARM Cortex-M7 core with FPU and DSP extensions, 300 MHz maximum CPU clock, 2 MB embedded Flash with ECC, 384 KB SRAM, 16-bit external bus interface with 24-bit address space, and a wide peripheral set including HS USB, CAN-FD, Ethernet MAC, SDMMC, image sensor interface, high-speed SPI/TWI, 12-bit ADC, DAC, PWM timers, and EMAC with 1588 PTP support.
The device is built on an ultra-low-power process and supports 1.08 V to 1.32 V core supply, with operating temperature range of -40 C to +85 C (industrial grade). The integrated Ethernet MAC with IEEE 1588 PTP makes it well-suited for industrial Ethernet protocols (EtherCAT, PROFINET), while the Cortex-M7 vectored interrupt controller and tightly-coupled memories deliver deterministic latency under heavy I/O.
Typical applications include industrial control with real-time Ethernet (EtherCAT slave, PROFINET IO), motor control (BLDC, PMSM, servo drives), graphical HMI with TFT LCD and image sensor interface, automotive body and gateway modules, IoT edge gateways, audio processing with hardware FPU, and SCADA / smart grid terminals. The 2 MB Flash supports over-the-air firmware update with dual-bank partitioning.
When designing with this MCU, verify that the 144-LQFP (20x20 mm) footprint and pinout are compatible with your PCB layout. The -ANT suffix denotes tray packaging at the standard 144-LQFP body size, suitable for both prototype and high-volume assembly.

主な用途
ATSAMS70Q21B-ANT の用途: 6 件s: Industrial Ethernet (EtherCAT / PROFINET), BLDC / PMSM Motor Control, Graphical HMI with TFT Display, IoT Edge Gateway, Audio Processing / DSP Front-End, Automotive Body / Gateway Module.
Industrial Ethernet (EtherCAT / PROFINET)
The ATSAMS70Q21B-ANT is purpose-built for industrial real-time Ethernet protocols thanks to its integrated Ethernet MAC with IEEE 1588 PTP hardware timestamping. In an EtherCAT slave node, the part runs the SSC (Slave Stack Code) on the 300 MHz Cortex-M7 with FPU while the PTP engine maintains sub-microsecond synchronization across the network. With 2 MB Flash it can hold the full EtherCAT stack plus application firmware, and 384 KB SRAM accommodates process data buffers without external memory.
おすすめ
BLDC / PMSM Motor Control
Motor control applications leverage the ATSAMS70Q21B-ANT's hardware FPU and DSP extensions to execute field-oriented control (FOC) loops at PWM frequencies up to 30 kHz on multiple three-phase motors. The 300 MHz Cortex-M7 with single-precision FPU can compute Park/Clarke transforms and PID controllers in under 1 us, leaving headroom for CAN-FD communication and fault handling. Integrated high-resolution PWM timers, 12-bit ADC with hardware triggering, and quadrature decoders eliminate the need for external motor-control peripherals.
おすすめ
Graphical HMI with TFT Display
For human-machine interface (HMI) panels, the ATSAMS70Q21B-ANT drives TFT LCDs through its integrated image sensor interface and high-speed SPI peripherals. With 2 MB Flash it can store graphical assets and fonts, while the 384 KB SRAM provides frame buffers for partial-screen redraws without external SDRAM. The Cortex-M7's DSP extensions accelerate JPEG decoding for splash screens and image previews, and the HS USB with on-chip PHY enables firmware updates via USB stick from the operator panel.
おすすめ
IoT Edge Gateway
IoT edge gateways built on the ATSAMS70Q21B-ANT consolidate multiple field-bus interfaces (CAN-FD, RS-485, Ethernet) and bridge them to cloud uplinks via Wi-Fi or LTE modules. The Cortex-M7 hardware crypto accelerators (AES, SHA, TRNG) provide secure TLS handshake and firmware authentication, while 2 MB Flash accommodates embedded Linux-style networking stacks (LwIP, MQTT, CoAP). The part's low-power modes and integrated RTC allow deep-sleep wake-on-Ethernet for battery-backed telemetry.
おすすめ
Audio Processing / DSP Front-End
Audio processing applications exploit the ATSAMS70Q21B-ANT's Cortex-M7 DSP extensions and hardware FPU to implement real-time effects (reverb, EQ, compression) and multi-channel mixing. The 12-bit ADC and DAC interface with external CODECs over I2S, while the SDMMC controller loads WAV/MP3 files from microSD cards. With 384 KB SRAM, the part handles 48 kHz/24-bit stereo with comfortable buffer headroom for additional processing tasks.
おすすめ
Automotive Body / Gateway Module
Automotive body and gateway modules use the ATSAMS70Q21B-ANT as a central node aggregating CAN-FD messages from ECUs and re-routing over Ethernet to the backbone. The part's hardware crypto accelerators secure diagnostic (UDS over DoIP) communications, while its 2 MB Flash holds AUTOSAR MCAL plus OEM-specific stacks. Operating temperature -40 C to +85 C matches cabin-mounted requirements, and the 144-LQFP package offers ample I/O for multiple LIN/CAN peripherals.

設計ノート
The ATSAMS70Q21B-ANT requires separate supplies: VDDIO 3.0-3.6 V for I/O, VDDIN 3.0-3.6 V for core LDO input, and VDDPLL with clean filtering for the PLL. Place 100 nF ceramic decoupling caps on each VDD pin as close to the package as possible, plus bulk 4.7 uF on VDDIN and 1 uF on VDDPLL. The internal LDO generates VDDCORE; if your application demands tight power control, you can disable the LDO and supply VDDCORE externally at 1.2 V. Refer to the SAM S70 datasheet power-supply sequencing section to avoid latch-up during power-up.
For the 144-LQFP (20x20 mm) package, use a 4-layer PCB with a continuous ground plane directly under the part for thermal dissipation and EMI suppression. Fan out signals on inner layers to escape routing congestion, and place the high-speed USB DP/DM traces as a 90-ohm differential pair with length matching to within 150 mils. Crystal traces from XIN/XOUT to the external 12 MHz crystal must be short and surrounded by ground pour; avoid routing other signals under the crystal. Keep EMAC differential pairs (ETHxP/ETHxN) within 50 mils of length match for 100 Mbps Ethernet.
Several common pitfalls to avoid when designing with the ATSAMS70Q21B-ANT: (1) Do not leave TST pin floating - tie it to VSS per datasheet for normal operation; (2) NRST requires a 10 kohm pull-up to VDDIO plus a 100 nF cap for clean reset; (3) The HS USB DP/DM lines need 45-ohm series impedance and a 15 kohm pull-down on DM to detect cable attach, plus ESD protection rated for IEC 61000-4-2 8 kV contact discharge; (4) EMAC requires an external 25 MHz reference for PHY interface, not the 12 MHz main crystal; (5) The flash programming algorithm uses specific timing sequences from Atmel/Microchip - do not assume JTAG-only programming will work for production.
