ATSAME70Q19A-AN Visão geral
An ARM Cortex-M7 microcontroller is a 32-bit RISC processor core designed by ARM that combines high clock speed with single-precision and double-precision floating-point hardware, optional SIMD DSP extensions, and tightly-coupled memories (TCM) that allow deterministic zero-wait-state code execution. The Cortex-M7 sits at the top of the Cortex-M family, positioned above Cortex-M4 in performance and below Cortex-A application processors. Microcontrollers integrating M7 belong to the broader category of embedded microcontrollers (MCU), a superset of microprocessors that bundles CPU, RAM, Flash, and peripherals into a single IC.
Key features include a 300 MHz Cortex-M7 core with double-precision FPU, 16 KB I-cache and 16 KB D-cache, 384 KB of additional SRAM in addition to the 256 KB system SRAM, up to 512 KB Flash, an EMAC 10/100 Ethernet MAC, dual CAN-FD controllers, a 12-bit ADC with up to 24 channels, a high-speed USB Host/Device plus PHY, an image sensor interface, and a TFT LCD controller. The device operates from 1.62 V to 3.6 V I/O and supports industrial-grade temperature ranges.
The ATSAME70Q19A-AN leverages superscalar pipeline architecture with branch prediction, hardware multiply-accumulate, and tightly-coupled instruction/data memories. The Ethernet MAC, USB High-Speed PHY, and dual CAN-FD enable high-bandwidth wired connectivity, while the integrated TFT LCD controller and hardware image sensor interface support advanced HMI and vision pipelines.
Typical applications include industrial automation controllers, building automation gateways, smart energy and smart metering nodes, automotive aftermarket infotainment, medical patient-monitoring terminals, and high-end HMI panels. The combination of Ethernet, CAN-FD, and HS USB makes it a strong fit for Industry 4.0 edge nodes.
When designing with this device, ensure decoupling follows Microchip's recommended 100 nF + bulk capacitor arrangement near each supply pin. For high-speed interfaces (HS USB, RMII, SDRAM), controlled-impedance routing and length matching are essential to remain within the datasheet's signal-integrity budget.

Aplicações típicas
ATSAME70Q19A-AN é adequado para 6 aplicaçãos: Industrial Automation Controller, Building Automation Gateway, Smart Energy Metering Node, High-End HMI Touch Panel, Medical Patient-Monitoring Terminal, Automotive Aftermarket Infotainment.
Industrial Automation Controller
The ATSAME70Q19A-AN's 300 MHz Cortex-M7 with FPU and 512 KB Flash deterministically executes multi-axis motion control loops at kHz rates, while its dual CAN-FD controllers handle real-time fieldbus traffic from drive amplifiers and remote I/O. 256 KB SRAM accommodates both the EtherCAT or PROFINET stack and firmware buffers. The 144-LQFP package simplifies hand-prototype and rework on shop-floor retrofit systems.
Recomendado
Building Automation Gateway
The integrated 10/100 Ethernet MAC plus high-speed USB host enables the ATSAME70Q19A-AN to bridge BACnet/IP, KNX/IP, Modbus TCP, and RS-485 building subnets into a single managed gateway. 512 KB Flash is sufficient for a TLS stack, while the 256 KB SRAM comfortably handles concurrent TLS sessions. Industrial-grade temperature supports mechanical-room operation, and the 144-LQFP allows robust lead-through-via mechanical assembly.
Recomendado
Smart Energy Metering Node
The ATSAME70Q19A-AN's 12-bit ADC at 1 MSPS samples multiple CT and shunt current channels with cyclic buffering, while a Cortex-M7 DSP pipeline computes RMS, THD, and reactive power. CAN-FD interconnects groups of meters for high-resolution tier-2/3 metering. Hardware AES through the optional cryptographic variant secures DLMS/COSEM communications, and the industrial temp range supports outdoor cabinet installations.
Recomendado
High-End HMI Touch Panel
The ATSAME70Q19A-AN's integrated TFT LCD controller, hardware image sensor interface, and high-speed USB for touch/gesture data make it ideal for 5-7 inch operator interface panels with live video overlay. The 300 MHz Cortex-M7 drives LVGL/STEMWIN widgets smoothly while leaving headroom for OPC-UA pub/sub. The 144-LQFP industrial-temp variant (A-AN suffix) supports factory-floor HMI designs.
Recomendado
Medical Patient-Monitoring Terminal
The ATSAME70Q19A-AN's deterministic Cortex-M7 core plus FPU runs real-time DSP for ECG, SpO2, and respiration signal processing at kHz sampling rates. The 12-bit ADC plus external 16/24-bit companion ADCs interface to standard medical front-ends. Industrial-grade reliability from Microchip's medical-grade supply chain supports regulatory paths, while the 144-LQFP package simplifies prototyping on the bench.
Recomendado
Automotive Aftermarket Infotainment
Although the SAM E70 family is not AEC-Q100 qualified, the ATSAME70Q19A-AN suits aftermarket connected-car devices like telematics, OBD-II gateways, and head-unit controllers where automotive qualification is not mandated. The Cortex-M7 + FPU drives LVDS, CAN-FD, and Ethernet connectivity for ADAS sensors; 512 KB Flash hosts the connected-car stack plus OTA bootloader with cryptographic verification.

Principais diferenciais
- Highest SRAM-to-Flash ratio with industrial temp at 300 MHz Cortex-M7 (vs ATSAME70N19B-AN)
- Full GMII Ethernet MAC plus HS USB 2.0 PHY on chip (vs ATSAME70J19B-AN)
- Identical pinout but B silicon revision for errata fix (vs ATSAME70Q19B-AN)
Notas de projeto
Provide a clean 3.3 V rail to VDDIO and VDDCORE (the on-chip LDO converts 3.3 V to 1.2 V core). Place a 100 nF X7R ceramic within 5 mm of every supply pin plus a 4.7 uF bulk capacitor at the regulator output. Avoid running high-current digital traces under the IC because 300 MHz switching current can couple into analog ADC references; route the analog ground GNDA back to a star ground to keep reference noise below the ADC's 12-bit LSB.
The 144-LQFP (20x20 mm) package uses 0.5 mm pitch pads and is friendly to 4/4 mil trace-and-space PCBs but tightens escape routing under the body. Use dog-bone fanouts between pads or via-in-pad for inner BGA escape equivalent. Maintain continuous GND planes on all inner layers under the device to provide a low-impedance return path for the 300 MHz core switching transients.
Match trace lengths within 150 mil for parallel NOR/SRAM memories and within 50 mil for SDRAM byte lanes. For RMII Ethernet, keep trace length delta under 50 mil between CLK and TX/RX pairs to the external PHY; series-terminate if total length exceeds 50 mm. For HS USB, follow the 90 ohm differential design rule and minimize stub length on DP and DN less than 200 mil total.
Do not assume the ATSAME70Q19A-AN silicon revision is automatically compatible with code generated for the A revision - check the errata document on Microchip's product page for any module differences. Always keep a debug JTAG or SWD header accessible; solder-bridged QFP pins at 0.5 mm pitch are common mistakes that are tedious to rework. Also, ensure the boot configuration pins (BOOT0/BOOT1) have valid logic at reset via a 10 k pull-up or pull-down.
