MPN： ATSAME54P19A-CTUT-EFP ⚠ 最後購買機會ATSAME54P19A-CTUT-EFP 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals into one IC. The SAM E54 family sits within the Cortex-M4F tier of the ARM Cortex-M hierarchy (Cortex-M0 -> Cortex-M3 -> Cortex-M4F -> Cortex-M7), and Microchip positions it between the SAM D51 and SAM E70 families. The Cortex-M4F adds single-precision floating point and DSP extensions, making it suitable for signal conditioning, motor control loops, and digital filter computation while remaining deterministic for real-time control.
Key features include a 120 MHz Cortex-M4F core with FPU, 512 KB dual-panel Flash with ECC, 192 KB SRAM with ECC, a high-speed 120 MHz peripheral bus, Full-Speed USB 2.0 with integrated PHY, 10/100 Mbps Ethernet MAC, CAN-FD, and multiple SERCOM interfaces. The device also exposes a 12-bit ADC up to 1 Msps, DAC outputs, and PWMs suited to digital power conversion. The EFP suffix indicates Extended Flash Performance characteristics for industrial temperature operation.
Typical applications include industrial Ethernet gateways, USB-to-UART/CAN bridges, building automation controllers, point-of-sale terminals, and motor-control front-ends. The combination of high-speed USB, CAN-FD, and Ethernet MAC on the same die eliminates external PHY/MAC chips for many industrial networking designs. The dual-panel Flash with ECC enables live firmware updates with minimal downtime.
When designing with this part, allocate decoupling capacitance of at least 100 nF on every VDD pin and 4.7 µF bulk capacitance near the LDO output. The TFBGA-120 package requires 4-layer PCB with 0.8 mm pitch fanout and laser-drilled or via-in-pad escape for reliable assembly. Confirm errata DS80000764 before committing to high-volume layout.

ATSAME54P19A-CTUT-EFP 適用於 6 應用s: Industrial Ethernet Gateway, USB-to-CAN Bridge, Building Automation Controller, Point-of-Sale Terminal, Motor Control Front-End, IoT Sensor Hub.
Industrial Ethernet Gateway
The ATSAME54P19A-CTUT-EFP integrates a 10/100 Mbps Ethernet MAC and CAN-FD on-chip, eliminating the need for external MAC chips in industrial gateway designs. Operating at 120 MHz Cortex-M4F, it handles TCP/IP stacks, Modbus/TCP routing, and CAN-to-Ethernet bridging simultaneously. An external RMII PHY (such as KSZ8081) connects to dedicated MAC pins on the 120-TFBGA package, while CAN-FD links to industrial sensor networks. With 192 KB SRAM, multiple concurrent sockets are supported, and the dual-panel Flash with ECC enables fail-safe OTA firmware updates in unattended field installations.

主要差異化特點
- Same-family migration within Microchip SAM E5x (對比ATSAME54N19A-AU-EFP)
- Higher memory headroom in compatible package family (對比ATSAMD51P19A-CTUT-EFP)
- Extended Flash Performance qualification (對比ATSAME53N20A-AU-EFP)
設計說明
The 120-TFBGA package uses 0.5 mm ball pitch in a 12x12 array on an 8x8 mm body. Recommended PCB layout: 4-layer stack-up with continuous GND plane on layer 2, 0.4 mm via-in-pad or microvia escape from each ball, and 0.2 mm trace width. Non-solder-mask-defined (NSMD) pads with 0.3 mm diameter improve assembly yield. Per Microchip SAM E54 hardware design guide, fanout all signals to breakaway routing channels before reaching the BGA perimeter to simplify layout review.
Estimated: total supply current at 120 MHz with all peripherals enabled is approximately 80 mA from VDDIN (3.3 V) and 25 mA from VDDANA. Place a 4.7 µF X7R bulk capacitor within 5 mm of the VDDCORE pin, and a 100 nF X7R decoupling capacitor on every VDD and VDDIO pin. Use a ferrite bead between VDDIN and VDDCORE if analog noise must be isolated. Estimated total worst-case power is approximately 0.35 W, requiring thermal relief via GND copper pour.
Before committing to layout, review errata DS80000764 for the SAM E54 family. Common pitfalls include: USB PLL lock time requires 1 ms after crystal start; Ethernet RMII timing requires 50 MHz clock with ±50 ppm stability; SERCOM I2C pins are 5V-tolerant only when configured to open-drain mode with slew-rate limiting; and the dual-panel Flash requires bootloader support for live updates. Enabling the cache controller improves execution speed by 30% but adds 1 cycle latency to first-instruction fetches after sleep wake.
