LPC4315JBD144E - Dual-Core 204MHz ARM MCU | NXP
部品番号: LPC4315JBD144E ✓ 生産中LPC4315JBD144E 概要
An Arm Cortex-M4/M0 microcontroller is a type of 32-bit microcontroller, itself part of the embedded processor and embedded systems hierarchy. The Cortex-M4 core handles performance-oriented control, communications, and signal-processing tasks, while the Cortex-M0 coprocessor can service peripheral operations independently. This division can reduce interrupt-related load on the primary core and supports deterministic multi-peripheral designs without requiring a separate controller.
The LPC4315JBD144E combines 768 KB of flash with the LPC43x family capacity of up to 1 MB, 136 kB of on-chip SRAM, and 16 kB of EEPROM. Peripherals include Ethernet, two high-speed USB ports, an LCD interface, a quad SPI Flash Interface, the State Configurable Timer, and Serial General Purpose I/O. These resources make the microcontroller suitable for gateways, human-machine interfaces, data acquisition equipment, and connected industrial controllers.
The dual-core architecture provides a practical way to partition control and communication workloads. The primary Cortex-M4 core can execute application logic and higher-bandwidth network routines, while the Cortex-M0 core can handle auxiliary I/O or peripheral tasks. The exact clock, voltage, timing, peripheral-enable, and temperature details for each device variant must be confirmed in the NXP manufacturer datasheet before final firmware and hardware configuration.
Typical uses include Ethernet-connected industrial equipment, USB-to-serial data acquisition systems, LCD-equipped operator panels, SPI Flash update systems, and embedded gateways. The 144-LQFP package exposes substantially more I/O than smaller microcontroller packages, making the device appropriate for designs requiring multiple buses, parallel LCD data, Ethernet connectivity, and USB host or device functions.
Designers should allocate the pin multiplexing, clocks, power rails, and boot options from the device-specific pin table before PCB routing. Firmware must also account for separate Cortex-M4 and Cortex-M0 startup and peripheral ownership. Use the manufacturer datasheet for the exact pin names and boot configuration, and validate the PCB against the selected package and revision.
This product page combines the manufacturer overview, distributor identification, package information, application guidance, and same-family replacement analysis into an engineering-focused reference. It highlights the role of the Cortex-M4/M0 architecture, memory resources, connectivity peripherals, PCB considerations, and qualification steps that raw distributor listings do not explain.

主な用途
LPC4315JBD144E の用途: 6 件s: Industrial Ethernet Gateway, USB Data Acquisition System, LCD Operator Panel, SPI Flash Firmware Update System, Embedded Programmable Controller, Connected Sensor Hub.
Industrial Ethernet Gateway
The LPC4315JBD144E fits industrial Ethernet gateways because it combines a 204 MHz Arm Cortex-M4 core with an Arm Cortex-M0 coprocessor, 768 KB of flash, and an integrated Ethernet interface. The primary core can manage protocol processing and application logic while the secondary core handles selected time-sensitive peripheral tasks. Its 144-LQFP package also exposes the pins required for Ethernet, external memory, control signals, and expansion interfaces. A production design still requires an appropriate Ethernet PHY, clock and reset circuitry, isolated or non-isolated network interface as required by the system, and firmware that assigns peripherals between the two cores.
おすすめ
USB Data Acquisition System
The LPC4315JBD144E is appropriate for a USB-connected data-acquisition controller because the manufacturer identifies two high-speed USB interfaces alongside the dual-core Arm Cortex-M4/M0 architecture. The Cortex-M4 can process acquisition logic and control a data path, while the Cortex-M0 can service triggered or concurrent peripheral operations. With 768 KB of flash, the device can hold application firmware, configuration data, and update routines in one package. Board implementation must assign the USB roles, connector protection, and clock sources according to the manufacturer configuration tables and must validate enumeration behavior in both host and device use cases.
おすすめ
LCD Operator Panel
The LPC4315JBD144E can serve as the central controller in an LCD-equipped operator panel because NXP identifies LCD support together with 768 KB of flash, up to 136 kB of family SRAM, and an Arm Cortex-M4 processor running up to 204 MHz. The high pin count of the 144-LQFP package provides access to LCD data and control signals alongside Ethernet and USB connectivity. The dual-core arrangement allows display updates or input handling to be partitioned from the main application. Designers should verify the selected LCD electrical interface, panel timing, touch-controller arrangement, backlight control, and pin-mux settings in the exact device documentation.
おすすめ
SPI Flash Firmware Update System
The LPC4315JBD144E is suited to firmware update and data-storage systems using its quad SPI Flash Interface. The 768 KB of internal flash supports a substantial embedded application, while SPIFI can provide an external pathway for larger images, configuration data, or staged updates. The 204 MHz Cortex-M4 core can execute protocol and validation tasks, and the Cortex-M0 coprocessor can support partitioned I/O work where software permits. Firmware should include image authentication, interruption-safe write sequencing, rollback logic, and boot-option validation before updating an external SPI Flash device in the field.
おすすめ
Embedded Programmable Controller
The LPC4315JBD144E suits embedded programmable-control equipment because its dual-core design combines a 204 MHz Cortex-M4 with a Cortex-M0 coprocessor and configurable State Configurable Timer and SGPIO resources. The main core can execute motion, sequencing, or process-control logic, while the secondary core can handle repetitive timing and I/O servicing. The 144-LQFP package offers substantial pin access for sensors, actuators, communication links, and external memory. Configuration must account for independent core startup, peripheral ownership, interrupt routing, clock trees, and safety behavior when one core encounters a fault during a control cycle.
おすすめ
Connected Sensor Hub
The LPC4315JBD144E works as a connected sensor hub where Ethernet, two high-speed USB interfaces, SGPIO, and multiple timer resources are useful for aggregating measurements and coordinating communications. Its 768 KB of flash allows the hub to retain networking, buffering, diagnostics, and update code locally, while the Cortex-M0 can service selected capture or interrupt-driven tasks. The 144-LQFP package supports the numerous digital connections expected in an industrial hub. A robust implementation should define sensor timing, isolate high-current actuators from sensitive measurement grounds, and use the manufacturer clock and power-sequencing requirements to prevent signal-integrity issues.

設計ノート
Route Ethernet, USB, LCD, and external memory interfaces according to the manufacturer reference layout and impedance rules. Keep clocks away from noisy switching nodes, provide short ground-return paths, and place interface protection close to connector entry points. Because the 144-LQFP footprint is dense, review the final pad assignment for pin multiplexing conflicts before releasing the PCB.
Implement the manufacturer-recommended supply network, bulk storage, and high-frequency bypass capacitors at each required power pin. Confirm voltage limits, power-up sequencing, and reset behavior from the exact device documentation. Do not infer capacitor values from the LPC43x family overview; use the LPC4315JBD144E electrical characteristics and reference circuit when populating the power rails.
Treat the Cortex-M4 and Cortex-M0 cores as independently started firmware domains. Define boot order, peripheral ownership, interrupt routing, shared-memory boundaries, and a recovery strategy for a stalled secondary core before production firmware is finalized. Rebuilding for another LPC43x member may require changing the linker script, boot configuration, pin muxing, or enabled peripherals even when the package remains unchanged.
Validate Ethernet and USB signal integrity with the selected PHY, connector, reference plane, and stack-up. The MCU's Ethernet and two high-speed USB interfaces require clean clocking and controlled impedance, while LCD and SGPIO signals should remain separated from switching-power nodes. Check rise and fall times against input thresholds rather than relying only on nominal clock frequency.
