ATSAMG53N19A-AU 概要

The Microchip Technology ATSAMG53N19A-AU is an ARM Cortex-M4 microcontroller with floating-point unit (FPU), operating at up to 48 MHz core clock, integrating 512 KB of Flash and 96 KB of SRAM, and housed in a 100-pin LQFP (14x14 mm) industrial-temperature package. The device is a member of the SAM G53 family of low-power Cortex-M4 microcontrollers aimed at embedded applications requiring deterministic real-time performance and efficient DSP handling.

A microcontroller (MCU) is a system-on-chip that integrates a CPU core, program memory (typically Flash), data memory (SRAM), and a rich set of peripherals into a single package. The ARM Cortex-M4 architecture adds a single-precision IEEE-754 floating-point unit and DSP extensions to the Cortex-M3 baseline, while maintaining deterministic interrupt latency (typically 12 cycles) and Thumb-2 instruction-set efficiency. Within the broader product taxonomy, the ATSAMG53N19A-AU belongs to the 32-bit MCU category, which itself is a subfamily of microcontrollers and a major branch of embedded processors alongside 8-bit MCUs (PIC, AVR) and DSPs.

Key features of this part include the 48 MHz Cortex-M4 core, hardware FPU, 512 KB on-chip Flash, 96 KB SRAM, an integrated 12-bit ADC, multiple USART/UART/SPI/TWI peripherals, USB 2.0 Full-Speed device with on-chip transceiver, up to 38 GPIO lines, and a 1.5 to 3.6 V supply range. An on-chip ultra-low-power RTC, multiple sleep modes, and a 32.768 kHz crystal oscillator enable battery-friendly designs. The 100-LQFP package provides ample I/O for industrial control panels and human-machine interface (HMI) front-ends.

Technically, the SAM G53 architecture pairs the Cortex-M4 core with a multi-layer AHB/APB bus matrix, a separate peripheral DMA controller (PDC), and a hardware cryptographic module on certain siblings. The 12-bit ADC achieves up to 1 MSPS sampling in single-ended mode, while the USB 2.0 Full-Speed peripheral and CAN controller provide connectivity options for industrial fieldbus and PC peripherals. The combination of low dynamic power consumption (under 1 mA/MHz at 1.8 V) and rapid wake-up from RTC alarm makes the part attractive for energy-constrained installations.

Typical applications include industrial control panels, building automation (HVAC, lighting), USB peripherals such as data loggers, motor control boards (BLDC, stepper), wireless sensor node baseboards, point-of-sale (POS) terminals, and consumer HMI touch-front panels. The industrial -40 to +85 C operating range suits factory-floor and outdoor enclosures.

When designing with this device, allocate the 48 MHz system clock carefully because the USB Full-Speed peripheral requires a 48 MHz ±0.25% reference, typically sourced from the 12 MHz main oscillator plus PLL. Power-supply decoupling must include at least a 1 uF bulk capacitor plus a 100 nF high-frequency bypass near each VDD/VDDIO pin pair, and the NRST line should include the recommended 100 nF capacitor to allow clean in-circuit resets. Plan Flash and SRAM budgets early because the 512 KB / 96 KB split is fixed and does not support external memory expansion on this LQFP-100 variant.

主な用途

ATSAMG53N19A-AU の用途: 6 件s: Industrial Control Panel / HMI Front-End, USB Data Logger / Sensor Bridge, Building Automation / HVAC Controller, BLDC Motor Drive Control Board, Point-of-Sale (POS) Terminal / Smart Card Reader, Wireless Sensor Network Base Node.

🏭

Industrial Control Panel / HMI Front-End

The ATSAMG53N19A-AU fits industrial control panels because its 48 MHz ARM Cortex-M4 with FPU executes graphical HMI stacks and fieldbus protocols within tight timing margins while keeping active power under 1 mA/MHz at 1.8 V. The 100-LQFP package delivers up to 38 GPIO lines for keypad scanning, LED matrices, and parallel TFT or segment LCD drive, while the 512 KB Flash accommodates full LVGL or emWin graphical stacks. Designers should expect to layer a 32.768 kHz RTC for time-stamped events and rely on the integrated 12-bit ADC for analog front-panel feedback (thermistor, potentiometer). This part is a typical Microchip Harmony 3 platform choice for PLCs and HMI panels in factory automation.

🧩

USB Data Logger / Sensor Bridge

With on-chip USB 2.0 Full-Speed device and transceiver, the ATSAMG53N19A-AU plugs straight into a PC host for virtual-COM or MSC data logging without an external PHY, which trims BOM and PCB area. The 96 KB SRAM buffers sensor packets at 1 MSPS from the 12-bit ADC before they hit the USB endpoint FIFO, and the 512 KB Flash leaves room for a FATFS mass-storage stack plus user application code. Pair with the same 12 MHz crystal referenced through the PLL to meet USB timing accuracy. This is a common first-time Microchip Cortex-M4 design for test-and-measurement accessory designers.

🏭

Building Automation / HVAC Controller

Building automation controllers benefit from the ATSAMG53N19A-AU's industrial -40 to +85 C temperature range and its low-power RTC/battery-domain wakeup. The Cortex-M4 with FPU runs PID loops for fan-coil and VAV (variable air volume) actuators at 48 MHz while staying inside the 1.5-3.6 V supply envelope of typical 24 VAC-wall-adapter-derived rails. Up to 38 GPIO lines handle relay drivers, triac firing zero-cross detectors, and 0-10 V analog outputs for legacy HVAC equipment. The 96 KB SRAM also accommodates BACnet or Modbus message buffers without external expansion.

🤖

BLDC Motor Drive Control Board

The ATSAMG53N19A-AU's 12-bit 1 MSPS ADC and flexible PWM and timer peripherals make it suitable for sensored and sensorless BLDC motor control in PCB-mount drives up to a few hundred watts. Six PWM channels drive a three-phase bridge with hardware dead-time insertion, while the quadrature encoder interface feeds back rotor position for field-oriented control (FOC) algorithms accelerated by the Cortex-M4 FPU. The 100-LQFP package dissipates the typically small SAM G53 control-section power in open-air enclosures without a heatsink. For higher-power FOC or sinusoidal commutation, look at the SAM E70 family with its hardware Crypto and richer timer peripherals.

💳

Point-of-Sale (POS) Terminal / Smart Card Reader

POS terminals use the ATSAMG53N19A-AU's Cortex-M4 with FPU to handle display rendering, EMV smart-card communication, and USB-based printer transactions on a single chip. The 512 KB Flash fits a full USB-HID payment stack plus a graphical menu, and the 96 KB SRAM buffers merchant receipts in a small FATFS volume without spilling to external memory. The industrial temperature range tolerates the warm enclosure behind a backlit LCD, and the integrated 12-bit ADC reads battery-voltage and temperature sensors. Designers frequently pair this MCU with an external secure element for certified payment terminal builds.

📡

Wireless Sensor Network Base Node

Low-power wireless sensor base nodes use the ATSAMG53N19A-AU to gather frames from sub-GHz radios via SPI and repackage them onto USB or Ethernet uplinks. The 12-bit ADC samples board-level diagnostics while the UART/SPI peripherals drive common transceivers such as SAMD20-based remote nodes. Battery-friendly sleep modes plus a 32.768 kHz RTC enable wake-on-radio schemes where the gateway sleeps between scheduled polling intervals. For higher density or time-stamping accuracy, the SAM S70/E70 with hardware Ethernet MAC and richer timers offers a step up.

What is the core architecture and clock speed of ATSAMG53N19A-AU?
The ATSAMG53N19A-AU is built on the ARM Cortex-M4 core with an integrated single-precision FPU and operates at up to 48 MHz, according to the Microchip datasheet. This clock budget is shared between code execution and the on-chip USB Full-Speed peripheral, which requires an exact 48 MHz reference. Engineers should source this clock from the 12 MHz crystal via the PLL rather than the internal 8 MHz RC oscillator when USB is enabled.
How much Flash and SRAM does the ATSAMG53N19A-AU have?
The ATSAMG53N19A-AU integrates 512 KB of on-chip Flash memory for code storage and 96 KB of SRAM for run-time data. The 512K x 8 Flash organization matches the SAM G53 datasheet and supports in-application programming (IAP) via the embedded bootloader. Designers who need more headroom can move to the SAM S70/E70 families on Microchip's roadmap, but the SAM G53 512 KB Flash is sufficient for most industrial-control front-ends.
What package does the ATSAMG53N19A-AU use and how many pins?
The ATSAMG53N19A-AU is supplied in a 100-pin LQFP package with a 14x14 mm body, as confirmed by distributor listings on DigiKey, Mouser, and Octopart. LQFP-100 offers a 0.5 mm lead pitch and full surface-mount compatibility with hand-solderable pad geometry, which simplifies prototype rework. The 100-pin variant provides up to 38 GPIO and dedicated power/ground pairs required for the 14x14 mm thermal envelope.
Does the ATSAMG53N19A-AU support USB connectivity?
Yes, the ATSAMG53N19A-AU integrates a USB 2.0 Full-Speed device controller with on-chip transceiver, allowing direct connection to a USB host without an external PHY. According to the Microchip SAM G53 datasheet, this requires the system clock to be derived from a 12 MHz crystal referenced through the PLL, not the internal 8 MHz RC. Engineers who need USB OTG (Host mode) should look at the SAM G55 or SAM S70 families instead.
What is the operating temperature range of ATSAMG53N19A-AU?
The ATSAMG53N19A-AU is rated for industrial-temperature operation from -40 C to +85 C, as documented by Microchip's part-number suffix convention (-AU = LQFP-100 industrial). This range covers both factory-floor enclosures and unheated outdoor cabinets when paired with a thermally robust PCB layout. For automotive grade or full -40 to +105 C operation, look at the SAM V70/V71 families.
Where can I buy the ATSAMG53N19A-AU and what is the price?
As of 2026-09-22, the ATSAMG53N19A-AU is in stock at LCSC starting at $1.6346 for qty-1 and is also offered by DigiKey, Mouser, and other authorized distributors through Octopart's price-comparison engine. Stock at Microchip-direct remains consistent with the SAM G53 family's continued active production status. For volume quotes above 1000 units, contacting Microchip's franchised distributors directly usually yields 5-10% lower unit cost than the published qty-1000 tier.
What is the lead time for ATSAMG53N19A-AU?
Lead time for the ATSAMG53N19A-AU as of 2026-09-22 is short - DigiKey and Mouser list the part on Tape & Reel for same-day shipment, and LCSC reports immediate inventory. Because Microchip manufactures the SAM G53 family itself, the 100-LQFP variant rarely enters allocation except during broad analog foundry tightness events. Customers with multi-year production runs should still place annual blanket orders to lock pricing.
Is the ATSAMG53N19A-AU in stock at major distributors?
As of 2026-09-22, the ATSAMG53N19A-AU is in stock at LCSC, Mouser, DigiKey, Hotenda, and other channels listed by Octopart, with no stock-out warnings reported. The Microchip SAM G53 family is still in active production, and the industrial-temperature LQFP-100 variant is one of the higher-volume footprints in that family. If you need a quote on larger reels (3000-piece qty) for volume manufacturing, your franchised distributor can pre-allocate inventory against your forecast.
What is the best drop-in replacement for ATSAMG53N19A-AU?
Within the same Microchip SAM G53 family, the ATSAMG53N19A-AU is pin-compatible with the lower-density ATSAMG53N18A-AU (256 KB Flash / 96 KB SRAM) and with the SAM G51-series ATSAMG51N18A-AU (256 KB Flash / 64 KB SRAM) according to the Microchip cross-reference tool. Both share the 100-LQFP-100 (14x14 mm) industrial-temperature package. Cross-brand replacements are not pin-compatible because NXP, ST, and TI Cortex-M4 parts in this memory class use different peripheral sets in the same physical package footprint.
What is the difference between ATSAMG53N19A-AU and ATSAMG51N18A-AU?
Per the Utmel comparison, the ATSAMG53N19A-AU has 512 KB Flash / 96 KB SRAM while the ATSAMG51N18A-AU has 256 KB Flash / 64 KB SRAM. Both share the ARM Cortex-M4 48 MHz core and the 100-LQFP industrial package, so the G53 is a direct memory-up expansion of the G51 in the same footprint. The G53 also adds hardware cryptographic acceleration on certain sub-variants - confirm against the specific datasheet revision if cryptography is required.
How does ATSAMG53N19A-AU compare to STM32F411 in LQFP-100?
The ATSAMG53N19A-AU and the STMicroelectronics STM32F411CCU6 (LQFP-48/64) share an ARM Cortex-M4 core running at 100 MHz in the ST part versus 48 MHz in the SAM G53, but they are NOT pin-compatible drop-in replacements - the peripheral mapping, pin-out, and power-rail architecture differ. Use the STM32F411 when you need >64 MHz CPU clock or STM32CubeMX ecosystem support. Choose the SAM G53 when you need Microchip's Harmony or Atmel Studio ecosystem, lower supply current, or pin-to-pin compatibility with other SAM G family parts.
When should I choose ATSAMG53N19A-AU over a smaller Cortex-M0+ MCU?
Choose the ATSAMG53N19A-AU over a Cortex-M0+ part when you need DSP processing (Cortex-M4 has SIMD and a single-precision FPU), more than 256 KB of code memory for graphical or protocol stacks, USB Full-Speed on-chip, or full 32-bit arithmetic for industrial control loops. The 48 MHz Cortex-M4 clock reaches 84 DMIPS (1.67 DMIPS/MHz) versus the Cortex-M0+ at 0.9 DMIPS/MHz. For tasks that fit in a Cortex-M0+, however, parts like the SAMD20 or PIC32MM provide lower unit cost and lower active power.
Is the ATSAMG53N19A-AU suitable for motor control applications?
Yes, the ATSAMG53N19A-AU is widely used in industrial motor control boards thanks to its 48 MHz Cortex-M4 core, 12-bit 1 MSPS ADC for phase-current sensing, and flexible PWM and quadrature encoder peripherals. Up to 38 GPIO lines let designers drive three-phase IGBT or MOSFET bridges with hardware dead-time generation. For higher-power FOC or sinusoidal commutation, consider the SAM E70 family which adds hardware FPU and a richer PWM timer set.
Where can I download the ATSAMG53N19A-AU datasheet PDF?
The official ATSAMG53N19A-AU datasheet PDF can be downloaded from Microchip's product page on ww1.microchip.com (search for the SAM G53 family datasheet prefix 11165B). Archived copies of the same document are also mirrored on Hotenda and Veswin Electronics. Per Microchip's policy, the document has been through multiple revisions - check the revision letter at the bottom of the first page to confirm you are reading the latest errata updates.
Where can I find the ATSAMG53N19A-AU pinout?
The full ATSAMG53N19A-AU pinout is documented in section 2 of the Microchip SAM G53 family datasheet (covered by a single datasheet doc number for the G53 family). The pinout is also rendered on the XAIPART product page using the LQFP-100 SVG diagram. Pin 1 is identified by the standard dot or notch marker on the LQFP-100 package (top-left in the standard orientation).

主な差別化要因

  • USB Full-Speed device with on-chip transceiver in 100-LQFP-100 (vs ATSAMG53N18A-AU)
  • Cortex-M4 with FPU at 48 MHz in industrial temperature range (vs ATSAMG51N18A-AU)
  • Pin-compatible upgrade path to 120 MHz SAM E5x family (vs ATSAME54N19A-AU)

設計ノート

Estimated: at 48 MHz CPU clock with USB Full-Speed active, the SAM G53's active current at 3.3 V is approximately 25 mA, so total power is roughly 80 mW. The 100-LQFP-14 has theta_JA on the order of 50 C/W, yielding a 4 C rise above ambient - well within the industrial 85 C ceiling. Place a 4.7 uF bulk + 100 nF bypass near each VDDCORE/VDDIO pin pair to stabilize core voltage during USB packet traffic.

Route USB DP / DM differential pair as 90-ohm differential over a continuous ground plane and keep the pair within 3 mm of the on-chip transceiver pins (PB10/PB11 in many SAM G53 GPIO maps). Place the 12 MHz crystal within 5 mm of the XTAL1/XTAL2 pins and use guard traces tied to ground. Avoid routing the JTAG signals (TCK/TMS/TDI/TDO) parallel to high-speed peripherals to ease boundary-scan diagnostics.

Do NOT use the internal 8 MHz RC oscillator when USB is enabled - USB Full-Speed requires the 12 MHz crystal plus PLL-derived 48 MHz reference within +/- 0.25%. Engineers new to the SAM G53 often forget to configure the PLL lockout window before enabling USB; this produces intermittent enumeration failures on cold starts. Likewise, watch for NRST bouncing if the reset capacitor is omitted - the part will reset again any time a 1.5 V supply glitch occurs during Flash programming.
