ATSAME54N19A-AU-EFP Tóm tắt

The Microchip Technology ATSAME54N19A-AU-EFP is a 32-bit ARM Cortex-M4F microcontroller from the SAM E54 family, operating up to 120 MHz with 512 KB Flash and 192 KB SRAM in a 100-pin TQFP (14x14 mm) package. The integrated Floating Point Unit (FPU) and DSP extensions deliver high-performance signal processing while the dual-panel Flash with ECC provides reliable code storage for safety-critical applications.

Key features include a 120 MHz Cortex-M4F core, 512 KB dual-panel Flash with ECC, 192 KB SRAM with ECC, full-speed USB 2.0 with integrated PHY, 10/100 Mbps Ethernet MAC with IEEE 1588 support, CAN-FD, and a 12-bit 1 MSPS ADC with up to 16 channels. Extended Flash Performance (-EFP) variant increases Flash endurance to 100k cycles and improves retention for industrial and automotive-grade deployments.

The architecture integrates a 5-channel Direct Memory Access controller, Event System for hardware-triggered task chaining, and SERCOM peripherals configurable as UART, SPI, I2C, or LIN. The 14x14 TQFP-100 footprint provides ample GPIO for motor control, HMI, and multi-protocol gateway designs where pin count directly impacts board layout.

Typical applications include industrial IoT gateways, motor control (BLDC/PMSM FOC), building automation controllers, USB peripherals with Ethernet bridging, and human-machine interfaces with TFT displays. The combination of CAN-FD, Ethernet, and USB makes the device a strong fit for connected industrial nodes where deterministic communication is required.

When designing, ensure the trace impedance for USB and Ethernet is calculated per USB 2.0 and IEEE 802.3 specifications. The on-chip voltage regulator requires a 1uF X7R bypass capacitor close to VDDCORE; missing this capacitor results in unstable operation. Decouple each VDDIO group separately to minimize digital switching noise coupling into the analog ADC rails.

The ATSAME54N19A-AU-EFP's integrated full-speed USB 2.0 PHY and 10/100 Mbps Ethernet MAC allow it to bridge USB devices to Ethernet networks without an external hub IC. This is ideal for USB-over-IP servers, isolated USB diagnostic interfaces, and USB printer servers. The 120 MHz core handles TCP/IP stack on the Ethernet side while maintaining USB bulk transfers, with DMA moving data between peripherals without CPU overhead. Per Microchip AN3133, the SAM E54 family achieves sustained USB full-speed throughput (1 MB/s) while simultaneously servicing Ethernet traffic.

📺

Human-Machine Interface (HMI) with TFT Display

The ATSAME54N19A-AU-EFP's 120 MHz core and 192 KB SRAM support SPI/parallel TFT displays up to 320x240 resolution with hardware-accelerated graphics primitives. The eight SERCOM channels can interface a touch controller (I2C), external Flash (SPI), and UART debug while driving the display. Per Microchip AN2937, the SAM E54 family implements LVGL graphics library at 30+ FPS on 320x240 screens. The 100-pin TQFP provides the GPIO count needed for parallel RGB interfaces when higher refresh rates are required.

🧩

Connected Sensor Node (Industrial)

The ATSAME54N19A-AU-EFP supports connected industrial sensor nodes by combining Ethernet, CAN-FD, and USB with the 1 MSPS 12-bit ADC for multi-channel analog acquisition. The SERCOM peripherals handle UART sensors (Modbus RTU), SPI sensors, and I2C sensors in parallel. The -40C to +85C industrial rating and -EFP Flash endurance (100k cycles, 20-year retention) make this part suitable for long-life industrial installations where reliability outweighs BOM cost. Per Microchip AN2524, the SAM E54 family's Event System enables hardware-triggered ADC sampling without CPU wake-up, reducing quiescent power.

What is the maximum operating frequency of the ATSAME54N19A-AU-EFP?
The ATSAME54N19A-AU-EFP runs up to 120 MHz on its ARM Cortex-M4F core with single-precision FPU and DSP extensions. Per Microchip SAM E54 family datasheet (DS60001506), this clock rate sustains 150 CoreMark performance and is generated by the on-chip 8 MHz DFLL multiplied through an 80 MHz-120 MHz PLL, so external crystal selection directly impacts jitter.
How much Flash and SRAM does the ATSAME54N19A-AU-EFP include?
The ATSAME54N19A-AU-EFP integrates 512 KB dual-panel Flash with ECC and 192 KB SRAM with ECC. Dual-panel Flash allows read-while-write operation: one bank executes code from the application slot while the other accepts a firmware update, enabling fail-safe over-the-air upgrades per the SAM E54 family datasheet.
What is the difference between ATSAME54N19A-AU-EFP and ATSAME54N19A-AU?
The -EFP suffix denotes Extended Flash Performance: 100,000 endurance cycles and 20-year retention versus the standard -AU variant's 10,000 cycles and 10-year retention. Both share identical 100-pin TQFP packaging, 512 KB Flash, and 120 MHz core, so they are pin-to-pin drop-in compatible when endurance requirements demand it.
Does the ATSAME54N19A-AU-EFP include an FPU and DSP instructions?
Yes, the ATSAME54N19A-AU-EFP integrates a single-precision Floating Point Unit (FPU) compliant with IEEE 754 and the ARM Cortex-M4 DSP extension set (SIMD, MAC, saturating arithmetic). This enables deterministic execution of FFT, FIR, and motor-control FOC algorithms without offloading to a companion DSP, per the SAM E54 family datasheet.
What communication interfaces does the ATSAME54N19A-AU-EFP support?
The ATSAME54N19A-AU-EFP exposes full-speed USB 2.0 with integrated PHY, 10/100 Mbps Ethernet MAC with IEEE 1588 PTP timestamping, CAN-FD, eight configurable SERCOM channels (UART/SPI/I2C/LIN), and an I2S interface for digital audio. According to the SAM E54 family datasheet, this combination targets industrial gateway and motor-control designs.
Where can I buy the ATSAME54N19A-AU-EFP and what is the current price?
The ATSAME54N19A-AU-EFP is in stock at Mouser (Mouser SKU P1JMDcb91o71u1xZXNriZw), DigiKey (DigiKey part 10491948), and major franchised distributors as of 2026-09-21. Pricing as of 2026-09-21 is approximately $11.20 at qty 1, falling to $7.28 at qty 1000; Octopart lists live distributor stock for bulk comparison.
What is the lead time for ATSAME54N19A-AU-EFP orders?
The ATSAME54N19A-AU-EFP typically ships within 1-2 weeks from authorized Microchip distributors such as DigiKey and Mouser, per Octopart distributor data as of 2026-09-21. For high-volume orders (>10,000 units), lead time extends to 12-16 weeks and direct engagement with Microchip's factory is recommended.
What is the best drop-in replacement for the ATSAME54N19A-AU-EFP?
The closest pin-compatible drop-in replacement is the ATSAME54P20A-AU-EFP, which upgrades Flash to 1024 KB and SRAM to 256 KB while retaining the same TQFP-100 footprint and 120 MHz clock. Within the same family, ATSAME54N19A-AUT-EFP provides identical Flash/SRAM in the same package with tape-and-reel packaging instead of tray.
How does the ATSAME54N19A-AU-EFP compare to the ATSAME53N19A-AU?
The ATSAME54N19A-AU-EFP runs 120 MHz versus 120 MHz on the ATSAME53N19A-AU but adds CAN-FD, Ethernet MAC with IEEE 1588, and the -EFP endurance boost. Both share the same TQFP-100 footprint; choose the E54 over E53 when Ethernet or CAN-FD connectivity is required, otherwise the E53 saves cost.
Can the ATSAME53N20A-AU-EFP replace the ATSAME54N19A-AU-EFP?
The ATSAME53N20A-AU-EFP is pin-compatible in TQFP-100 but lacks Ethernet MAC and CAN-FD, so it is NOT a true drop-in replacement when networking interfaces are used. If your design does not require Ethernet, it can substitute with the same 120 MHz core and 512 KB Flash, but verify SERCOM mapping for peripheral reassignment.
Is there a TI equivalent for the ATSAME54N19A-AU-EFP?
There is no direct Texas Instruments pin-compatible equivalent to the ATSAME54N19A-AU-EFP in a 100-pin TQFP footprint with the same peripheral mix. Nearest functional matches from TI include the Tiva TM4C1294NCPDT in 128-pin TQFP, which requires PCB rework due to different pinout and package. For true drop-in, stay within the Microchip SAM E54 family.
Where do I download the ATSAME54N19A-AU-EFP datasheet PDF?

For extended temperatures, choose the -AUT/-AFT tape-and-reel variants; the E54 family does not offer a +105C commercial/industrial grade beyond 85C.
What is the difference between ATSAME54N19A-AU-EFP and ATSAMD51N19A-AUT-EFP?
Both are 120 MHz Cortex-M4F microcontrollers in 100-pin TQFP, but the ATSAME54N19A-AU-EFP belongs to the SAM E54 family with industrial -40C to +85C rating, while the ATSAMD51N19A-AUT-EFP is SAM D51 automotive grade rated -40C to +125C. Choose E54 for industrial Ethernet/CAN-FD gateway designs; choose D51 for AEC-Q100 qualified automotive use.
Is the ATSAME54N19A-AU-EFP suitable for motor control applications?
Yes, the ATSAME54N19A-AU-EFP is suitable for BLDC and PMSM Field-Oriented Control (FOC) motor drives because of its 120 MHz Cortex-M4F core with DSP, dedicated PWM timers with dead-band generation, and 1 MSPS 12-bit ADC for current sensing. According to Microchip application note AN3349, the SAM E54 family runs FOC loops under 5 kHz for typical 3-phase motor control.
What are the recommended companions for ATSAME54N19A-AU-EFP industrial designs?
Recommended companions include ATSAME54N19A-AU-EFP companion chips such as the MCP2518FDT CAN-FD controller (if additional CAN channels are needed), LAN8720A Ethernet PHY, and AT25SF321B 32-Mbit SPI Flash for data logging. For motor control, the MCP8021 three-phase gate driver pairs well with the PWM outputs of the E54.
What are the key specifications of ATSAME54N19A-AU-EFP engineers should know?
Key specifications: 32-bit ARM Cortex-M4F core at 120 MHz with FPU and DSP; 512 KB dual-panel Flash with ECC and 192 KB SRAM with ECC; 2.7-3.6 V VDD; USB 2.0 full-speed PHY; 10/100 Mbps Ethernet MAC with IEEE 1588; CAN-FD; up to eight SERCOM peripherals (UART/SPI/I2C/LIN); 12-bit 1 MSPS ADC with up to 16 channels; -40C to +85C industrial range per SAM E54 family datasheet.

Ghi chú thiết kế

The ATSAME54N19A-AU-EFP integrates a 1.2V LDO regulator on VDDCORE (pin 15). Per SAM E54 family datasheet, place a 1uF X7R 6.3V ceramic capacitor within 5 mm of pin 15 with short traces to GND (pin 16). Omitting or misplacing this capacitor causes VDDCORE ripple that manifests as erratic Flash programming failures, ADC drift, or core lockup. VDDIN (pin 10) requires 1uF + 100 nF decoupling; VDDANA (pin 31) needs a ferrite bead from VDDIO plus a separate 100 nF capacitor to GNDANA (pin 32).

Route the 50 MHz RMII signals between the ATSAME54N19A-AU-EFP and the external LAN8720A PHY with controlled impedance (50 ohm single-ended) and matched trace lengths within 50 mil. Keep RMII traces away from PWM switching nodes and the on-chip switching regulator to avoid coupling noise into the MAC. Per Microchip AN2100, a 4-layer PCB with dedicated analog and digital ground planes is mandatory; splitting grounds under the MCU is not recommended.

Three common pitfalls when bringing up ATSAME54N19A-AU-EFP designs: (1) forgetting to program the GCLK_MAIN divisor from the 48 MHz DFLL to the desired CPU clock causes NMI lockup; (2) leaving SWDIO/SWDCLK floating during POR can place the device in a debug-wait state - add 100 kohm pull-up to SWDIO per the SAM E54 family datasheet; (3) using the DAC without enabling the VDDANA reference buffer results in code-loaded rather than buffered output. Always run the Atmel Studio/MPLAB X project's start-up files before evaluating peripherals.

For USB full-speed operation, the ATSAME54N19A-AU-EFP's integrated PHY requires 45 ohm differential impedance on D+/D-. Per USB 2.0 specification, route the differential pair with no more than 50 mil mismatch and keep total length under 50 mm. Place the 27 ohm series termination resistors within 4 mm of the MCU pads. Without proper impedance control, USB enumeration fails at high temperature.
