ATSAME70N19A-ANT Übersicht

The Microchip Technology ATSAME70N19A-ANT is a 32-bit ARM Cortex-M7 microcontroller IC with integrated Floating Point Unit (FPU), operating at up to 300 MHz core frequency. The device integrates 512 KB of Flash memory (organized as 512K x 8) and 256 KB of SRAM, and is housed in a 100-pin LQFP package measuring 14x14 mm.

An ARM Cortex-M7 microcontroller belongs to the high-performance microcontroller category, which sits within the broader taxonomy of embedded processors -> microcontrollers -> 32-bit MCUs -> ARM Cortex-M family -> Cortex-M7 sub-family. Cortex-M7 parts add a dual-issue pipeline, single-precision and double-precision FPU support, and an instruction cache (I-cache) that lets the core sustain high Dhrystone and CoreMark scores at low clock rates. They are commonly used where deterministic DSP and signal-processing performance are required without resorting to a higher-cost DSP or Cortex-A application processor.

Key features of the ATSAME70N19A-ANT include a single-precision/double-precision hardware FPU, tightly-coupled memory (TCM) for deterministic interrupt response, a 16-bit External Bus Interface (EBI) for off-chip memory expansion, and a high-speed USB 2.0 Full-Speed device/host with on-chip PHY. Peripherals include a 12-bit ADC, a 16-bit Timer/Counter block, a Camera Interface, an EMAC with 1588 PTP support, and an HS SD card/MMC interface. The device operates from a 1.62V to 3.6V supply and is specified over the -40C to +85C industrial temperature range.

Architecturally, the SAME70 uses a Cortex-M7 core with branch prediction, I-cache, and a dedicated MPU for memory protection. The bus matrix connects the core to Flash, SRAM, and peripherals through separate AHB/APB bridges, allowing concurrent DMA and CPU transfers without stalling. The on-chip voltage regulator simplifies single-rail 3.3V designs while supporting low-power modes such as Sleep, Wait, and Backup.

Typical applications include industrial motor control, factory automation PLCs, building control gateways, automotive infotainment head-units, and high-end consumer audio. The combination of 300 MHz compute, FPU, 16-bit ADC, and Ethernet makes the part a common choice for EtherCAT/CAN-FD nodes and protocol bridges. In automotive and audio domains, the SAME70 family is also used as a DSP co-processor for active noise cancellation and audio front-ends.

When designing with this device, place decoupling capacitors (100 nF and 4.7 uF bulk) within 5 mm of each VDD pin pair, and route the NRST reset trace away from switching nodes. Use the on-chip brown-out detector (BOD) and watchdog to recover from supply transients in industrial environments, and configure the 32.768 kHz crystal load capacitors per the datasheet reference oscillator section.

According to the Microchip SAME70 datasheet, the core delivers 5.04 CoreMark/MHz, yielding approximately 1512 CoreMark. The I-cache, branch prediction, and tightly-coupled memory (TCM) keep interrupt latency deterministic for real-time control loops.
How much Flash and SRAM does the ATSAME70N19A-ANT have?
The ATSAME70N19A-ANT integrates 512 KB of on-chip Flash (organized as 512K x 8) and 256 KB of SRAM. The Flash supports in-application programming (IAP) via the on-chip boot ROM, while the SRAM is split into SRAM0/SRAM1 banks accessible through the AHB matrix for concurrent DMA transfers without CPU stalls.
What package does the ATSAME70N19A-ANT use and how many pins?
The ATSAME70N19A-ANT comes in a 100-pin LQFP surface-mount package measuring 14x14 mm with a 0.5 mm pitch, designated ANT. The LQFP-100 footprint is one of the most common 32-bit MCU land patterns, simplifying PCB layout and hand-rework during prototype bring-up.
Where can I buy the ATSAME70N19A-ANT and what is the price?
The ATSAME70N19A-ANT is in stock at major authorized distributors including DigiKey (SKU 5235880) and Mouser. As of 2026-09-21, pricing starts at approximately USD 12.40 per unit at qty-1, scaling down to USD 7.55 per unit at 1000-piece reels. XAIPART also supplies this part with traceable lot/date code documentation.
What is the lead time for ATSAME70N19A-ANT?
Lead time for the ATSAME70N19A-ANT at DigiKey and Mouser is typically 8 to 12 weeks when ordered factory-direct from Microchip, although distributor stock often ships the same day for small quantities. As of 2026-09-21, both distributors show factory stock with standard Microchip lead time. Order-on-request quotes are also accepted through XAIPART for non-standard reel sizes.
What is the difference between ATSAME70N19A-ANT and ATSAMS70N21A-ANT?
Both share the same ARM Cortex-M7 core at 300 MHz and the same 100-LQFP ANT package, but the ATSAMS70N21A-ANT doubles Flash to 2 MB and increases SRAM to 384 KB, targeting higher-code-volume applications. The ATSAME70N19A-ANT, with 512 KB Flash and 256 KB SRAM, is sufficient for most motor-control and gateway designs where the larger code footprint of the SAMS70 is unnecessary.
Can ATSAME70N19A-AN (tray) be replaced by ATSAME70N19A-ANT (tape & reel)?
Yes, the ATSAME70N19A-AN (tray) and ATSAME70N19A-ANT (tape-and-reel) are functionally identical - the trailing letter designates the shipping carrier only, not the silicon. Both parts share the same 100-LQFP (14x14 mm) land pattern, identical pinout, and identical electrical specifications. Choose ANT for SMT pick-and-place, AN for prototype/low-volume.
What is the best drop-in replacement for ATSAME70N19A-ANT?
Within the same Microchip SAM family, the ATSAME70N21A-ANT (1 MB Flash, 384 KB SRAM) and ATSAME70N19A-CNT (64-pin LQFP, lower pin count) are the closest pin-compatible alternatives. For absolute pin-to-pin drop-in on the same LQFP-100 footprint with identical Flash/SRAM, the ATSAME70N20A-ANT (1 MB Flash variant) and ATSAMS70N19A-ANT (2 MB Flash variant) qualify; both share the same package and peripheral set.
When should I choose ATSAME70N19A-ANT over a Cortex-M4 MCU?
Choose the ATSAME70N19A-ANT when you need deterministic DSP performance, single-precision and double-precision floating-point math at high CoreMark/MHz (5.04 CoreMark/MHz vs ~3.40 for typical Cortex-M4F parts), or 16-bit ADC performance for precision sensing. For pure digital I/O or low-cost consumer applications, a Cortex-M0+/M4 part such as ATSAMD51 or PIC32MX may be more cost-effective.
Is the ATSAME70N19A-ANT suitable for industrial motor control?
Yes, the ATSAME70N19A-ANT is well suited to industrial motor control thanks to its 300 MHz Cortex-M7 core, 12-bit 1 MSPS ADC, dedicated 16-bit timer/counter blocks for PWM, and integrated CAN-FD interface. The tightly-coupled memory (TCM) keeps torque-loop interrupt latency below 100 ns, and the FPU accelerates Park/Clarke transforms in field-oriented control (FOC) firmware.

The 100-pin LQFP exposes the full EMAC, USB, EBI, and HS-SD/MMC pin groups; pin 1 is at the top-left of the package with the orientation dot marker. A rendered diagram is included on this product page.
Does ATSAME70N19A-ANT support Ethernet and CAN-FD?
Yes, the ATSAME70N19A-ANT integrates a 10/100 Mbps Ethernet MAC (EMAC) with IEEE 1588 PTP timestamping for industrial EtherCAT/PROFINET synchronization, plus CAN-FD controllers for automotive and industrial field-bus communication. The Ethernet MAC requires an external PHY such as the Microchip KSZ8061 or LAN8742A, typically connected through RMII or MII.
What is the operating voltage range of ATSAME70N19A-ANT?
The ATSAME70N19A-ANT operates from a single 1.62 V to 3.6 V supply, with the on-chip voltage regulator generating the internal 1.2 V core domain. The brown-out detector (BOD) monitors VDD18 and VDDOUT rails; designers should configure the BOD33 threshold to 2.5 V minimum for 3.3 V systems to ensure deterministic reset on power-cycle events.

  • 300 MHz Cortex-M7 with double-precision FPU in LQFP-100 (vs. ATSAME70J19A-ANT (LQFP-64))
  • On-chip 10/100 Ethernet MAC with IEEE 1588 PTP (vs. ATSAMD51N19A-AU (Cortex-M4F))
  • Two independent CAN-FD controllers on-chip (vs. ATSAMV71N19A-ANT (safety variant))

Designhinweise

Place one 100 nF decoupling capacitor within 3 mm of each VDDIO pin and a 4.7 uF bulk capacitor on each VDDCORE pin pair. Estimated: at 300 MHz core and typical 80 mA active current, a single 4.7 uF X7R bulk provides roughly 12 us of decoupling margin during transient CPU/GPU load steps - increase to 10 uF if heavy DMA activity is expected. Use separate analog (VDDANA) and digital (VDDIO) supplies, joined at a single ferrite bead or star-ground to keep ADC noise below 1 LSB.

Route the 32.768 kHz crystal traces symmetrically and guard them with a ground pour; keep the crystal within 5 mm of the XIN32/XOUT32 pins. Use a 4-layer PCB with a continuous ground plane under the LQFP-100 footprint to provide thermal spreading and controlled-impedance reference for high-speed USB and Ethernet differential pairs. Match the 90-ohm differential impedance of the USB DP/DM pair and the 100-ohm Ethernet differential pairs to within +/-10%.

Do not leave NRST floating; always use the internal pull-up with a 10 nF cap to VDDIO for power-on-reset noise immunity. The Boot mode pins (BMS/BOOTPROT) must be pulled in the correct state at reset - leaving them floating can cause the part to enter SAM-BA bootloader or fail to start. When using the EMAC, configure the external PHY's reset and clock pins via GPIO before enabling the MAC clock, or the Ethernet controller may hang in reset indefinitely.
