ATSAME70Q19B-ANT - 300MHz Cortex-M7 MCU 512KB Flash | Microchip
MPN： ATSAME70Q19B-ANT ✓ 啟用中ATSAME70Q19B-ANT 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash and SRAM), and programmable peripherals into one package. The Cortex-M7 is the highest-performance core in the ARM Cortex-M family, featuring a 6-stage superscalar pipeline, dual-issue instruction execution, and an optional FPU for single- and double-precision IEEE 754 floating-point math. Microcontrollers sit at the top of the embedded hierarchy along with microprocessors (MPU) and SoCs, but unlike MPUs they typically include on-chip memory and rich peripheral sets such as CAN, Ethernet, USB, and analog converters.
Key features of the ATSAME70Q19B-ANT include 512 KB Flash, 256 KB SRAM, a 12-bit ADC (AFE) and 12-bit DAC, dual CAN-FD interfaces, Ethernet MAC, USB 2.0 Full-Speed and High-Speed, and a 144-pin LQFP package providing 114 GPIO. The device operates from 1.62 V to 3.6 V supply and supports -40C to +105C industrial temperature range, making it suitable for harsh industrial environments. Integrated Single/Dual I2S, HSMCI (SD card), and image sensor interface support multimedia and vision applications without external controllers.
The ATSAME70Q19B-ANT uses a Harvard architecture with separate instruction and data buses, an MPU for memory protection, and DSP extensions including SIMD and MAC instructions. At 300 MHz it delivers up to 1500 CoreMark and 2.14 DMIPS/MHz, backed by 16 KB I-cache and 16 KB D-cache. Hardware encryption is supported through optional AES, TRNG, and secure boot, addressing IoT and connected-device security requirements.
Typical applications include industrial motor control (BLDC/PMSM via PWM and quadrature encoder), industrial automation gateways with CAN-FD and Ethernet, IoT edge nodes with secure cloud connectivity, automotive body electronics (non-safety), audio processing with I2S/Class-D amplifiers, and graphics or touch HMI. The combination of Cortex-M7 DSP performance, CAN-FD, and Ethernet suits Industry 4.0 nodes.
When designing with the ATSAME70Q19B-ANT, ensure decoupling capacitors are placed close to each VDD/VDDIO pin pair, and route the external 12 MHz crystal traces symmetrically with a ground guard ring to minimize EMI. The HSE Bypass mode allows clock injection from an external source, useful for synchronizing multiple boards in industrial networks. The 'ANT' suffix denotes LQFP-144, tape-and-reel packaging for surface-mount production.

典型應用
ATSAME70Q19B-ANT 適用於 6 應用s: Industrial Motor Control (BLDC/PMSM), Industrial Ethernet Gateway / PLC, IoT Edge Node / Smart Sensor, Automotive Body Electronics (Non-Safety), Audio Processing / Class-D Amplifier, Graphical HMI / Touch Display Controller.
Industrial Motor Control (BLDC/PMSM)
The ATSAME70Q19B-ANT's Cortex-M7 at 300 MHz executes field-oriented control (FOC) loops for BLDC and PMSM motors within the 10-20 kHz PWM cycle typical of industrial drives. With hardware floating-point, sine/cosine and Park transforms run in single-cycle instructions, freeing CPU headroom for sensorless observers and torque-ripple compensation. The 12-bit ADC (up to 24 channels) samples phase currents simultaneously via dual-sample-and-hold, while the high-resolution PWM timers generate complementary 3-phase outputs with programmable dead-time. The 144-LQFP package exposes 114 GPIO for encoder, Hall sensor, and communication interfaces, and the -40C to +105C industrial temperature grade supports drive cabinets.
推薦
Industrial Ethernet Gateway / PLC
The ATSAME70Q19B-ANT integrates a 10/100 Ethernet MAC and dual CAN-FD controllers, enabling single-MCU industrial gateways that bridge Modbus TCP, EtherNet/IP, or PROFINET with CAN-FD machine networks. The Cortex-M7 with FPU runs lwIP or equivalent TCP/IP stacks with line-rate throughput while leaving CPU cycles for application logic. With 256 KB SRAM it holds full TCP/IP buffers, CAN-FD message pools, and protocol stacks simultaneously. Hardware crypto (AES, TRNG) on adjacent variants secures OPC UA and TLS 1.2 connections. Operating from 1.7 V to 3.6 V and -40C to +105C supports DIN-rail mounted controller enclosures.
推薦
IoT Edge Node / Smart Sensor
The ATSAME70Q19B-ANT suits IoT edge aggregation nodes that process sensor data locally before cloud transmission. Its Cortex-M7 DSP extensions (SIMD, MAC) accelerate FFT, FIR filtering, and vibration analysis on raw accelerometer/microphone streams, running at 300 MHz with deterministic timing. USB 2.0 High-Speed enables firmware updates and debug, while Ethernet or CAN-FD handles upstream connectivity. The 512 KB Flash accommodates TLS stacks, OTA bootloaders, and application code concurrently. 114 GPIO in 144-LQFP provides rich sensor expansion; industrial -40C to +105C temperature range supports outdoor enclosures.
推薦
Automotive Body Electronics (Non-Safety)
For non-safety automotive body applications such as body controllers, climate-control HMI, or lighting modules, the ATSAME70Q19B-ANT delivers Cortex-M7 performance with CAN-FD for modern vehicle networks. The -40C to +105C industrial temperature grade survives cabin environments, and the 12-bit ADC handles sensor inputs directly. Hardware PWM and QEI interfaces simplify motor control for HVAC blowers and mirror adjustments. Note this part is not AEC-Q100 qualified; for safety-critical or AEC-Q100 requirements use the SAM V70/V71 family or an external automotive MCU.
推薦
Audio Processing / Class-D Amplifier
The ATSAME70Q19B-ANT's Cortex-M7 with FPU excels at real-time audio algorithms such as equalization, dynamics processing, and active noise cancellation, where DSP extensions accelerate biquad and FIR filter operations. The integrated I2S interfaces connect to audio ADCs/DACs for digital-input amplifiers or smart speakers. With 256 KB SRAM, it can buffer multi-channel audio frames at 48 kHz/24-bit while running effects processing. The 12-bit DAC supports auxiliary analog outputs (headphone detect, VU meter). Pair with a digital-input Class-D amplifier IC for high-efficiency audio products.
推薦
Graphical HMI / Touch Display Controller
The ATSAME70Q19B-ANT drives TFT LCD displays up to WXGA resolution using its parallel SMC interface, with HSMCI providing SD card support for asset libraries and logging. The Cortex-M7's 2.14 DMIPS/MHz runs LVGL or emWin graphics stacks with smooth animations and multitouch response. USB 2.0 HS enables fast asset uploads, while CAN-FD links to machine networks for status display. 114 GPIO in 144-LQFP supports capacitive touch sensing and backlight/LED drivers; the 256 KB SRAM accommodates display framebuffers and LVGL objects without external memory in many designs.

主要差異化特點
- Higher internal memory with same package (對比ATSAME70Q19A-ANT)

- Integrated hardware crypto accelerators (對比ATSAME70N21B-CNT)
設計說明
Place a 100 nF decoupling capacitor within 2 mm of every VDDIO/VDDCORE pin pair, plus one bulk 4.7 uF per supply rail. The LQFP-144 package has 9 VDDIO/VDDCORE pairs and 9 corresponding GND pins; missing even one bypass cap can cause brownouts under heavy DMA load. Add a ground pour on the top layer stitched with vias every 5 mm around the chip body for thermal relief and low-impedance return paths.
Do not leave the TST pin floating - tie it to VDDIO through a 10 kohm pull-up to disable boundary scan mode, otherwise the device may enter test mode at power-up. The NRST pin requires an external 10 kohm pull-up plus a 1 nF capacitor for clean reset; many prototype failures stem from missing reset RC components.
Route the external 12 MHz crystal traces (XIN/XOUT) symmetrically with lengths matched within 1 mm and surrounded by a grounded guard ring. Keep crystal traces away from PWM outputs and switching power nodes; aim for 5 mm minimum spacing. For HSE Bypass mode when using an external clock source, AC-couple the input and provide a clean 1.8 V clock to avoid jitter.
