ATSAME70Q19A-AN Ringkasan

The Microchip ATSAME70Q19A-AN is a high-performance 32-bit ARM Cortex-M7 microcontroller with FPU operating at up to 300 MHz, integrating 512 KB of Flash and 256 KB of SRAM in a 144-pin LQFP (20x20 mm) package. Part of the SAM E70 family, it is purpose-built for connectivity-rich embedded designs that require deterministic real-time performance, high-resolution graphics, and industrial-grade peripherals.

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.

This page synthesizes distributor pricing, drop-in alternatives within the SAME70 family, and practical PCB and thermal design notes that complement the official Microchip datasheet for the engineer evaluating this part for a new design.

What is the maximum operating frequency of the ATSAME70Q19A-AN?
The ATSAME70Q19A-AN runs the ARM Cortex-M7 core at up to 300 MHz, including single-precision and double-precision hardware FPU and DSP extensions. Achievable throughput is 1500+ CoreMark depending on memory placement in TCM versus flash, per the manufacturer datasheet. Cache misses are the primary limit on real-world execution speed at this clock rate, so latency-critical routines should be copied to SRAM or TCM.
How much Flash and SRAM does the ATSAME70Q19A-AN include?
The ATSAME70Q19A-AN integrates 512 KB of in-system programmable Flash and 256 KB of system SRAM, plus 16 KB instruction cache and 16 KB data cache. The cache and tight integration of peripherals let deterministic code run at full 300 MHz while leaving bulk RAM available for buffers and stacks, sufficient for typical industrial HMI and gateway workloads.
What is the difference between ATSAME70Q19A-AN and ATSAME70Q21A-AN?
The ATSAME70Q19A-AN is the 512 KB Flash / 256 KB SRAM member of the SAM E70 family, while the ATSAME70Q21A-AN doubles those resources to 2 MB Flash and 384 KB SRAM per the family datasheet. Both share the same 144-LQFP (20x20) package and identical peripheral set, so ATSAME70Q21A-AN is a drop-in upgrade on the same PCB when more code space is required.
Does the ATSAME70Q19A-AN include Ethernet and CAN-FD?
Yes - the ATSAME70Q19A-AN integrates a 10/100 EMAC (MII/RMII/GMII) plus two independent CAN-FD controllers supporting ISO 11898-1:2015. This combination suits industrial fieldbus gateways that bridge CAN-FD sensor/actuator networks to Ethernet backbones running EtherCAT, Modbus TCP, or PROFINET stacks, without requiring an external communications controller.
What is the operating voltage of the ATSAME70Q19A-AN?
The ATSAME70Q19A-AN operates from a 1.62 V to 3.6 V supply, with 3.3 V typical for full-speed operation including the high-speed USB PHY. Core voltage is internally regulated. Designers should still provide a clean 3.3 V rail with a minimum 100 nF decoupling capacitor adjacent to every VDDCORE, VDDIO, and VDDPLL pin to meet the datasheet's noise budget.
Where can I buy the ATSAME70Q19A-AN online?
The ATSAME70Q19A-AN is listed in stock at Microchip direct and authorized distributors including DigiKey, Mouser, and LCSC as of 2026-09-22. Pricing begins near USD 17.59 per unit at quantity 1 and falls to roughly USD 11.40 per unit at 1000 pieces; LCSC currently shows a single unit listing at $17.592. Order minimums vary, so confirm the distributor's quantity-break schedule before placing an order.
What is the lead time for the ATSAME70Q19A-AN?
Lead time for the ATSAME70Q19A-AN is factory-stock to 8 weeks depending on distributor, with Microchip direct and DigiKey typically shipping factory reels within 1-3 business days of order as of 2026-09-22. For higher volume commitments, contact Microchip FRAM Partners for allocation. In tight markets, request a confirmed schedule at PO time to avoid design risk from substitutions.
How does the ATSAME70Q19A-AN compare to the STM32F746?
The ATSAME70Q19A-AN delivers 300 MHz Cortex-M7 with 512 KB Flash plus an integrated 10/100 Ethernet MAC, while the STMicroelectronics STM32F746 runs at 216 MHz Cortex-M7 with up to 1 MB Flash. The SAM E70 has a higher core clock and more deterministic TCM integration; the STM32F746 has a richer graphics/touch peripheral set. Both share LQFP and similar BGA packages, so choice depends on peripheral and ecosystem priorities.
When should I choose ATSAME70Q19A-AN over ATSAME70N21A-AN?
Choose the ATSAME70Q19A-AN when 512 KB Flash and 256 KB SRAM are sufficient for your application and you need the 144-LQFP (20x20) package for industrial builds with hand-repair-friendly footprints. Choose the ATSAME70N21A-AN when you require 2 MB Flash, more SRAM, and the smaller 144-LQFP fine-pitch footprint; both share the SAME70 peripheral set so code porting is mechanical.
Is ATSAME70Q21A-ANR a drop-in replacement for ATSAME70Q19A-AN?
The ATSAME70Q21A-ANR offers 2 MB Flash and 384 KB SRAM and shares the same 144-LQFP (20x20) package, but it is a memory-variant upgrade, not a strict drop-in replacement. For a strict drop-in footprint-and-peripheral match within the SAME70 family, prefer ATSAME70Q19B-AN, ATSAME70N19B-AN, ATSAME70J19B-AN, or ATSAME70Q19A-CFN; these all share the LQFP-144 footprint and M7 + 300 MHz core.
What is the best cross-brand equivalent for ATSAME70Q19A-AN?
There is no true cross-brand drop-in for the ATSAME70Q19A-AN because the SAM E70's peripheral mix (CAN-FD plus HS USB PHY plus 10/100 Ethernet) is highly distinctive; closest cross-brand families are STM32F746NGH6 and NXP i.MX RT1052, both Cortex-M7 with comparable Flash density and Ethernet. Both require hardware revalidation and software porting - none are bit-pin equivalent.
Where can I download the ATSAME70Q19A-AN datasheet PDF?
The official ATSAME70Q19A-AN datasheet is hosted on Microchip's website in PDF form. The summary datasheet has been mirrored on alldatasheet.com (file size ~8 MB) and datasheet4u.com for convenience, but the authoritative source remains Microchip's device page. Bookmark the product URL https://www.microchip.com/en-us/product/ATSAME70Q19 to fetch the latest revision including errata and reference BOM.

Choose the ATSAME70Q19A-AN when your design is industrial-grade, requires 512 KB Flash with 256 KB SRAM, and needs the 144-LQFP (20x20) footprint for hand-prototype or low-volume manufacturing. It is the right fit for connectivity-rich applications combining Ethernet, dual CAN-FD, and high-speed USB on a single chip. Choose the ATSAME70Q19B-AN for new designs where the B silicon revision's errata fixes matter, or the ATSAME70N19B-AN when you need 1 MB Flash at the same 144-LQFP footprint. Choose the ATSAME70Q21A-AN if you need 2 MB Flash for richer graphics, firmware, or OTA update headroom. Avoid this part for AEC-Q100 automotive qualifications - look to the SAM V70/S70 family instead.

Diferensiator Kunci

  • Highest SRAM-to-Flash ratio with industrial temp at 300 MHz Cortex-M7 (vsATSAME70N19B-AN)
  • Full GMII Ethernet MAC plus HS USB 2.0 PHY on chip (vsATSAME70J19B-AN)
  • Identical pinout but B silicon revision for errata fix (vsATSAME70Q19B-AN)

Catatan Desain

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.
