部品番号: LPC4333JBD144E ✓ 生産中LPC4333JBD144E 概要
A microcontroller is a programmable embedded-system controller that integrates a processor core, memory, and peripherals on one semiconductor device. Within the product hierarchy, the LPC4333 belongs to the Arm Cortex-M4 microcontroller class and combines an application processor with an Arm Cortex-M0 coprocessor. The secondary core can handle independent control tasks while the main core executes application, communications, and real-time processing functions.
Key features include the dual-core Arm Cortex-M4/M0 architecture, a maximum 204 MHz operating frequency, 512 KB of flash memory, and 136 KB of SRAM. Communications and connectivity features include Ethernet, two high-speed USB ports, and a quad SPI Flash Interface, or SPIFI. The device also provides an LCD interface and enhanced multipoint microcontroller functionality, making it suitable for embedded systems requiring a broad mix of control and communications peripherals.
Technically, the LPC4333 family combines a 32-bit Cortex-M4 main core with a 32-bit Cortex-M0 coprocessor. The coprocessor is useful for peripheral control, diagnostic routines, background processing, or workload separation where independent execution can improve system responsiveness. Its extensive pin count provides access to multiple communication and general-purpose interfaces, while the 20 x 20 mm LQFP package supports conventional leaded-board assembly and inspection.
Typical applications include industrial gateways, Ethernet-connected controllers, USB-to-Ethernet equipment, human-machine interfaces, networked embedded systems, and real-time control platforms. The combination of Ethernet, two high-speed USB interfaces, LCD support, and dual-core processing supports designs that must combine human-interface connectivity, peripheral control, and network communications in one device.
Designers should verify the complete pin assignment, power requirements, peripheral multiplexing, and board-level support circuitry against the manufacturer datasheet before layout. LQFP-144 routing is demanding, but its exposed lead geometry supports solder-joint inspection and can simplify prototype assembly compared with a very fine-pitch BGA package.
This page consolidates the verified NXP and distributor information, focused drop-in alternatives, package-aware comparisons, and practical selection guidance to help engineers evaluate the LPC4333JBD144E for embedded networking, USB, and dual-core control designs.

LPC4333JBD144E の用途: 6 件s: Industrial Ethernet Gateway, USB-to-Ethernet Network Bridge, Human-Machine Interface Controller, Real-Time Industrial Control Panel, Connected Test and Measurement Instrument, Embedded Network Data Logger.
Industrial Ethernet Gateway
The LPC4333JBD144E fits an industrial Ethernet gateway because its 204 MHz Arm Cortex-M4 main core can process protocol traffic while the Arm Cortex-M0 coprocessor handles independent monitoring or peripheral-control tasks. Integrated Ethernet, 136 KB of SRAM, and 512 KB of flash support connected embedded designs without requiring an external network processor. The 144-LQFP package also provides many externally accessible pins for status indicators, serial consoles, and isolated field-bus interfaces. Engineers should use the NXP datasheet to confirm PHY support, pin multiplexing, termination requirements, clock topology, and EMC-sensitive layout before committing the board.
おすすめ
USB-to-Ethernet Network Bridge
The LPC4333JBD144E is suitable for a USB-to-Ethernet bridge because it combines two high-speed USB interfaces, Ethernet connectivity, and dual Arm Cortex-M4/M0 processing in one controller. The Cortex-M4 can execute USB and network stacks while the Cortex-M0 can service monitoring, status, or control functions, reducing the need for a separate microcontroller. Its 512 KB of flash and 136 KB of SRAM provide useful working memory for protocol and firmware storage. Layout must keep USB differential pairs controlled and Ethernet magnetics isolated from noisy power paths, with final pin assignments taken from the official LPC43xx datasheet.
おすすめ
Human-Machine Interface Controller
The LPC4333JBD144E can serve as a human-machine interface controller because it provides LCD support alongside 204 MHz processing, dual-core architecture, Ethernet, and two high-speed USB ports. The Cortex-M4 is suitable for graphics, touch handling, and user-interface logic, while the Cortex-M0 can supervise display updates, keypad scanning, or diagnostic routines. The 144-pin LQFP package exposes numerous GPIO and communication resources for buttons, indicators, and panel peripherals. Designers should verify the selected LCD interface pins, external memory requirements if applicable, and timing from the manufacturer datasheet.
おすすめ
Real-Time Industrial Control Panel
The LPC4333JBD144E fits a real-time industrial control panel by separating control tasks between the Arm Cortex-M4 and Arm Cortex-M0 cores. The main core can execute state-machine, communications, and application logic, while the coprocessor can respond to timing-sensitive peripheral events or service diagnostics. Ethernet supports supervisory communication, and the two high-speed USB interfaces can simplify service or configuration connectivity. A robust implementation must use the datasheet-defined clock sources, supply sequencing, reset behavior, and watchdog facilities, while PCB routing must preserve clean grounding around analog and communication interfaces.
おすすめ
Connected Test and Measurement Instrument
The LPC4333JBD144E is appropriate for a connected test and measurement instrument requiring network management, high-speed peripheral connectivity, and deterministic embedded control. The 204 MHz Cortex-M4 handles instrument control and data processing, the Cortex-M0 handles auxiliary monitoring, and the 512 KB flash provides room for firmware and configuration data. Ethernet and USB provide remote control and data-transfer paths, while LCD support simplifies a local operator interface. Design work should isolate analog measurement circuitry from digital activity and validate grounding, reference voltage, clock jitter, and peripheral multiplexing against the official documentation.
おすすめ
Embedded Network Data Logger
The LPC4333JBD144E supports an embedded network data logger by combining Ethernet connectivity, USB service access, LCD feedback, and dual-core processing. The Cortex-M4 can process logged data and communication tasks, while the Cortex-M0 can manage sensors, storage controls, or periodic sampling. Its 136 KB of on-chip SRAM assists with buffering and protocol handling, although external nonvolatile storage may still be required for extended logging. The design should account for Ethernet PHY placement, write-endurance controls, brownout behavior, and separation of high-current storage circuitry from sensitive digital signals.

設計ノート
Treat the LPC4333JBD144E Ethernet and USB interfaces as high-speed, layout-sensitive circuits. Confirm every multiplexed signal and pin from the official NXP package drawing before assigning connector or PHY nets. Keep USB differential traces length-matched and continuous over a continuous ground plane, place the Ethernet magnetic-device footprint according to its isolation guidance, and avoid routing Ethernet or USB through noisy switching-power regions. The exact compensation, impedance, and clearance requirements must come from the relevant interface specifications and NXP documentation.
Plan the power tree around all externally accessible and internally required supply pins rather than supplying only the names of the main core rails. Place local high-frequency decoupling at the relevant pins, provide adequate bulk capacitance near the device, and keep analog or peripheral supplies on separate branches where pin multiplexing permits it. Verify startup, reset, brownout, and current limits in the manufacturer datasheet before assigning the external supply sources. Estimated power values are not supplied because the verified data does not specify the complete operating mode and voltage configuration.
Do not treat a family member with the same 144-LQFP footprint as automatically interchangeable. Verify the LPC4333, LPC4337, LPC4353, and LPC4357 ordering codes for flash size, exposed functions, temperature grade, and package suffix, then compare the complete pin table. Also check the LPC43xx errata for the exact silicon revision. A mechanical footprint match is necessary for drop-in consideration, but it does not replace electrical, peripheral, and software compatibility checks.
LQFP-144 provides a leaded thermal path that is more forgiving than a fine-pitch BGA, but its performance still depends on copper area, airflow, and actual switching activity. Use the NXP package thermal information to determine allowable power dissipation for the installed board rather than relying on a generic junction-temperature estimate. Keep exposed-pad or thermal-via requirements consistent with the exact package drawing, and validate the final assembly under maximum processor, Ethernet, USB, and peripheral load.
