ATSAME70Q19B-ANT Présentation

The Microchip Technology ATSAME70Q19B-ANT is a 32-bit ARM Cortex-M7 microcontroller with Floating Point Unit (FPU), running up to 300 MHz, integrating 512 KB of Flash and 256 KB of SRAM in a 144-pin LQFP (20x20 mm) package. It is part of the SAM E70 family of high-performance flash microcontrollers designed for embedded connectivity, motor control, and industrial applications.

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.

The 'T' suffix indicates Tape-and-Reel packaging optimized for SMT production lines, while 'AN' without T ships in tray. Functionally interchangeable - both use the same 144-pin LQFP (20x20 mm) footprint. Choose T for assembly-line builds, non-T for prototyping or low-volume runs.
ATSAME70Q19B-ANT vs ATSAME70Q21B-ANT - which is better for motor control?
The ATSAME70Q19B-ANT and ATSAME70Q21B-ANT share the same Cortex-M7 core, peripherals, and 144-LQFP package; the Q21B variant doubles Flash to 2 MB and SRAM to 384 KB. For a typical BLDC or PMSM motor-control loop running at 20 kHz PWM with field-oriented control, both deliver ample headroom, but the Q21B's extra memory future-proofs application growth. Choose Q19B for cost-optimized designs and Q21B when adding Ethernet stacks or larger firmware.
When should I choose ATSAME70Q19B-ANT over STM32F407VGT6?
Choose the ATSAME70Q19B-ANT over the STM32F407VGT6 when you need the Cortex-M7's 6-stage superscalar pipeline plus FPU for DSP workloads, CAN-FD support, or extended industrial temperature grade (-40C to +105C). The Cortex-M4 on the STM32F407 is single-issue and lacks the dual-issue throughput. However, the STM32 ecosystem offers broader middleware (STM32Cube) and lower unit cost at high volumes. Both run in 144-LQFP but pin maps are not identical - PCB rework is required for cross-migration.
What is the best drop-in replacement for ATSAME70Q19B-ANT?
The best drop-in replacement for the ATSAME70Q19B-ANT in the same 144-LQFP footprint is the ATSAME70Q19A-ANT, the previous silicon revision (Q19A vs Q19B differs mainly in errata fixes - same Flash, SRAM, peripherals). For higher-memory needs in the same package, ATSAME70Q21B-ANT doubles Flash and SRAM. For industrial Ethernet gateway designs, ATSAME70N21B-CNT in 144-LQFP gives 2 MB Flash and adds crypto accelerators.
Can ATSAME70Q21B-ANT replace ATSAME70Q19B-ANT directly?
Yes, the ATSAME70Q21B-ANT can directly replace the ATSAME70Q19B-ANT on the same 144-LQFP PCB footprint. Both share identical pin assignments; the Q21B simply offers larger memory (2 MB Flash, 384 KB SRAM vs 512 KB and 256 KB). No firmware porting is required if your code fits within the smaller memory ceiling; you gain extra headroom with no changes to GPIO mapping.

For full register definitions, also download the SAMD/SAME70 header files and the Atmel/Microchip ASF or Harmony 3 framework from Microchip's MPLAB X ecosystem.
Where do I find the ATSAME70Q19B-ANT pinout diagram?
The pinout for the ATSAME70Q19B-ANT is documented in Section 4 of the SAM E70 family datasheet (DS60001527). The 144-pin LQFP package pinout is also available as a separate mechanical drawing on Microchip's packaging specifications page. The pin map includes 114 GPIO, multiple power/ground pairs, dedicated USB D+/D-, Ethernet RMII/MII pins, and CAN-FD TX/RX lines.
Is ATSAME70Q19B-ANT RoHS compliant?

Guide de sélection

Choose the ATSAME70Q19B-ANT when you need Cortex-M7 300 MHz performance with 512 KB Flash and 256 KB SRAM in the 144-LQFP (20x20) footprint for cost-sensitive industrial motor control, PLC, or IoT edge designs. Select the ATSAME70Q19A-ANT for lower-cost builds where the latest errata fixes are not required. Pick the ATSAME70Q21B-ANT when firmware exceeds 512 KB (Ethernet stacks, TLS, graphics) - same pinout, larger memory headroom. Choose the ATSAME70N21B-CNT when hardware crypto is mandatory for secure-boot applications. The ATSAME70J21A-ANT is appropriate when you need 2 MB Flash but only 128 KB SRAM is acceptable. All five share identical 144-LQFP pinout, enabling single PCB design across variants.

Principaux différenciateurs

  • Higher internal memory with same package (vs ATSAME70Q19A-ANT)
  • Quadruple Flash vs base Q19 (vs ATSAME70Q21B-ANT)
  • Integrated hardware crypto accelerators (vs ATSAME70N21B-CNT)

Notes de conception

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.
