ATSAME70Q20B-AN Обзор
A microcontroller (MCU) is a single-chip computer containing a processor core, memory, and programmable peripherals. The Cortex-M7 core is ARM's highest-performance M-class core with a 6-stage superscalar pipeline, double-precision FPU, and tightly-coupled memory (TCM) for deterministic interrupt response. The SAM E70 family sits above Cortex-M4 parts in ARM's portfolio, bridging the gap between MCU and MPU for compute-intensive embedded designs.
Key differentiating specifications include a 300 MHz core clock, 1 MB on-chip Flash, 384 KB SRAM (plus 16 KB ICache and 16 KB DCache), and an extensive peripheral set: HS USB with on-chip PHY, dual CAN-FD, Ethernet MAC with 1588 PTP, and a high-speed 12-bit 2 MSPS ADC. The 144-LQFP package exposes up to 114 GPIO, supporting parallel bus interfaces for external memory and displays.
Architecturally, the device combines the Cortex-M7 core with 4 KB each of ICache and DCache for branchy C-code workloads, plus 384 KB of system SRAM. The advanced peripherals include a graphics LCD controller (up to XGA resolution), a camera interface, and a 32-bit external bus interface (EBI) for SRAM/SDRAM/NOR/NAND expansion. A single 1.2 V internal LDO and 3.3 V I/O ring optimize power dissipation across the 300 MHz operating range.
Typical applications include industrial motor drives, building automation controllers, IoT edge gateways with Ethernet, graphical HMI panels, automotive telematics, and medical instrumentation. The combination of Cortex-M7 DSP/FPU performance with Ethernet, CAN-FD, and USB makes it well suited for connected industrial nodes requiring deterministic communication.
When designing with the ATSAME70Q20B-AN, ensure the 3.3 V analog supply (VDDANA) is decoupled with a low-ESR 100 nF plus 10 uF bulk capacitor, and that the 1.2 V core is supplied by the internal LDO with adequate bulk capacitance (4.7 uF + 100 nF) on VDDOUT. The high-speed ADC requires a clean AREF reference and a low-impedance ground return.

Типичное применение
ATSAME70Q20B-AN подходит для 6 применениеs: Industrial Motor Control Drives, Industrial IoT Edge Gateways, Graphical HMI Touch Panels, Automotive Telematics and Gateway ECUs, Medical Instrumentation and Patient Monitors, Building Automation Controllers.
Industrial Motor Control Drives
The ATSAME70Q20B-AN's 300 MHz Cortex-M7 with FPU and DSP extensions is ideal for field-oriented control (FOC) of PMSM and BLDC motors, executing the Park/Clarke transforms and PI loops with deterministic cycle times. The 12-bit 2 MSPS ADC samples three-phase current simultaneously via PWM-triggered sequencing, while the hardware quadrature decoder handles encoder feedback up to 32-bit position count. Compared to Cortex-M4 motor MCUs, the Cortex-M7's double-precision FPU halves torque-ripple calculation time and improves sinusoidal commutation accuracy at high RPM. The 1 MB Flash accommodates FOC firmware plus CANopen or EtherCAT slave stacks without external memory.
Рекомендуется
Industrial IoT Edge Gateways
The ATSAME70Q20B-AN integrates dual CAN-FD, 10/100 Ethernet with 1588 PTP timestamping, and HS USB with on-chip PHY - the three connectivity pillars required for industrial IoT edge gateways bridging Fieldbus to Ethernet. The Cortex-M7 runs a real-time OS (FreeRTOS or Zephyr) plus a TCP/IP stack with TLS 1.3, offloading encryption to the Cortex-M7's hardware AES accelerator. The 384 KB SRAM handles TCP/IP buffers and CAN-FD message queues without external memory. Compared to Cortex-M4 gateways, the ATSAME70Q20B-AN's higher clock and 1588 PTP hardware deliver sub-microsecond timestamping accuracy for synchronized distributed control.
Рекомендуется
Graphical HMI Touch Panels
The ATSAME70Q20B-AN's integrated LCD controller supports resolutions up to XGA (1024x768) at 24 bpp and a parallel RGB interface, enabling direct connection to mid-size TFT LCD panels used in building automation and factory HMI. The 32-bit EBI drives external SDRAM for frame buffers (e.g., 16 MB for 800x480@32 bpp), and the 300 MHz Cortex-M7 with FPU renders emWin or LVGL UIs smoothly. The hardware 2D acceleration (line draw, BLIT) accelerates graphics primitives without CPU overhead. Compared to Cortex-M4 HMI controllers, the E70's hardware 2D engine halves screen-update latency for animated gauges.
Рекомендуется
Automotive Telematics and Gateway ECUs
The ATSAME70Q20B-AN's dual CAN-FD controllers (8 Mbps), Cortex-M7 300 MHz performance, and automotive-grade temperature range make it suitable for telematics control units (TCUs) and central gateway ECUs. The Ethernet MAC with 1588 PTP timestamping bridges automotive Ethernet (100BASE-T1) to legacy CAN networks, while the Cortex-M7 runs AUTOSAR-classical applications and security stacks (HSM with hardware AES/SHA). Compared to Cortex-M4 automotive MCUs, the ATSAME70Q20B-AN's deterministic interrupt latency (12 cycles) improves AUTOSAR OS conformance for safety-critical body controllers.
Рекомендуется
Medical Instrumentation and Patient Monitors
The ATSAME70Q20B-AN's 12-bit 2 MSPS ADC with hardware oversampling and the Cortex-M7 DSP extensions enable accurate acquisition of ECG, EEG, and SpO2 signals in patient monitoring equipment. The single-precision FPU executes biquad filters and FFT-based heart-rate-variability analysis at the Cortex-M7's 300 MHz rate, well within the 1 ms sampling budget. The hardware AES accelerator secures patient data (HIPAA compliance) with minimal CPU overhead. Compared to Cortex-M4 medical devices, the E70's hardware oversampling ADC delivers 16-bit effective resolution for high-precision instrumentation.
Рекомендуется
Building Automation Controllers
The ATSAME70Q20B-AN powers BACnet, KNX, and Modbus building automation controllers with its Ethernet MAC, dual CAN-FD, and UART/SPI/TWI interfaces - covering all major building-automation Fieldbus protocols. The 300 MHz Cortex-M7 runs a real-time OS plus a BACnet/IP stack with scheduling, while the 16 KB ICache/DCache improves interrupt response for time-critical HVAC control loops. The hardware AES secures building-access credentials and TLS traffic to cloud-based management dashboards. Compared to Cortex-M4 controllers, the E70's dual CAN-FD and PTP-enabled Ethernet streamline multi-protocol gateway designs.

Заметки по проектированию
The ATSAME70Q20B-AN requires four distinct supply domains: VDDIO (3.3 V for I/O ring), VDDANA (3.3 V for analog blocks, must be low-noise with separate ferrite from VDDIO), VDDPLL (1.2 V derived from internal regulator or external), and VDDOUT (1.2 V core LDO output). Place a 100 nF + 10 uF ceramic + 4.7 uF bulk capacitor directly at VDDOUT pin 19, plus 100 nF at every VDDIO/VSS pin pair. A common design pitfall is sharing VDDIO and VDDANA - this couples switching noise into the 12-bit ADC reference, increasing ENOB by 1-2 bits of degradation.
The 144-LQFP package has thermal resistance theta_JA of approximately 35 C/W (with 4-layer JEDEC test board). At 300 MHz with all peripherals active, the device dissipates up to 1.5 W; in industrial environments with ambient up to 85 C, the junction temperature can approach 137 C, exceeding the 125 C limit. Recommended: ensure 2 oz copper on top and bottom layers with a copper area of at least 1.5 square inches directly under the exposed pad of LQFP-176 variants; for LQFP-144 use thermal vias array (0.3 mm pitch, 9 vias minimum) under the package center.
The high-speed 50 MHz EBI bus to external SDRAM requires careful impedance control - trace impedance 50 ohm single-ended, 100 ohm differential for clock pairs, trace length matching within +/- 250 mils. Place the SDRAM within 50 mm of the EBI pins and use series 33 ohm damping resistors on EBI_D[15:0] and address lines. Common pitfall: routing EBI_DQ across the same layer as switching power supply traces - keep at least 5 mm separation or use a ground guard trace to prevent crosstalk into the SDRAM controller.
Three common pitfalls when bringing up ATSAME70Q20B-AN designs: (1) Forgetting to configure the supply monitor (SUPC) before enabling the main voltage regulator - this can cause brown-out resets on cold start. (2) Not enabling the 16 KB ICache before jumping to external QSPI flash - this halves code execution performance. (3) Leaving the ERASE pin floating - it must be tied high through a 10 kohm pull-up, otherwise an ESD event can trigger a full Flash erase in the field.
Place the 32.768 kHz crystal XIN32/XOUT32 within 5 mm of pins 140/141 with grounded guard ring to prevent coupling of switching noise from the main oscillator. The 8-12 MHz main crystal on pins 142/143 should be similarly guarded, and both crystal traces must maintain symmetric length (delta < 1 mm). For USB applications, the 90 ohm differential D+/D- pair from the on-chip PHY must be routed as a length-matched pair with 90 ohm differential impedance, and the USB shield ground should connect to PCB ground at a single point near the connector.
