部品番号: LPC4323JET100E ✓ 生産中LPC4323JET100E 概要
A microcontroller is a programmable system-on-chip containing processor cores, memory, and configurable peripherals. The LPC4323JET100E belongs to the LPC43xx family of embedded microcontrollers, combining an Arm Cortex-M4 application processor with an Arm Cortex-M0 coprocessor. This architecture supports deterministic control tasks alongside higher-level embedded processing while keeping the implementation within a unified 100-pin package.
Key features include 512 KB of flash, 136 KB of SRAM, 16 KB of EEPROM, and two high-speed USB interfaces. The device also includes an LCD interface, Ethernet MAC, quad SPI Flash Interface, State Configurable Timer, and Serial General Purpose I/O interface. Its 3.3 V operating supply and 204 MHz maximum clock make it appropriate for connected embedded systems requiring substantial local memory and a broad peripheral set.
The Cortex-M4 core handles application processing, while the Cortex-M0 core can execute independent control or communication tasks. The high-speed USB ports support USB-connected data acquisition, configuration, or communications equipment. Ethernet connectivity, LCD support, and the SPIFI interface broaden the device beyond a basic control MCU, enabling consolidation of multiple functions on one board.
Typical applications include industrial data-acquisition equipment, USB-to-serial interface systems, test and measurement instruments, human-machine interfaces, networked embedded controllers, and connected industrial equipment. The LPC4323JET100E is particularly useful where local SRAM, dual processing capability, high-speed USB, and LCD connectivity must coexist in one compact controller.
Designers should use the manufacturer pin-description table and package drawing when assigning PCB routes, power connections, decoupling, and exposed-pad thermal provisions. USB and Ethernet interfaces also require careful controlled-impedance routing, return-path continuity, and isolation from noisy external circuits. Firmware should validate clock, USB, Ethernet, and peripheral initialization before enabling production operation.
This product page combines the manufacturer's device characteristics with engineering-focused application guidance, interface considerations, and a same-package replacement comparison. It helps designers evaluate the LPC4323JET100E against related LPC43xx devices while preserving the 100-pin TFBGA layout and the 204 MHz dual-core architecture.

主な用途
LPC4323JET100E の用途: 6 件s: Industrial Data Acquisition, USB Test and Measurement, Human-Machine Interface Controller, Networked Embedded Controller, High-Speed USB Interface Appliance, Secure Embedded Processing.
Industrial Data Acquisition
The LPC4323JET100E fits industrial data-acquisition controllers that combine sampling, local processing, and high-speed host communications. Its 204 MHz Arm Cortex-M4 core provides processing capacity, while the Cortex-M0 coprocessor can separate deterministic control tasks from the main application workload. The 512 KB of flash supports substantial firmware, and 136 KB of SRAM allows buffering of measurement data without continuous external-memory access. Two high-speed USB interfaces can support a host connection and a peripheral service connection, while Ethernet MAC provides a wired network path. Implemented between the analog front end and communication subsystem, the MCU reduces data-transfer latency and keeps acquisition control close to the sensor circuitry.
おすすめ
USB Test and Measurement
The LPC4323JET100E is appropriate for USB-connected test and measurement instruments that need local signal processing and two high-speed USB interfaces. The Arm Cortex-M4 core can execute control algorithms, protocol handling, and data formatting at up to 204 MHz, while the Cortex-M0 coprocessor can manage a separate timing-sensitive task. Its 136 KB of SRAM allows local sample buffering, and 512 KB of flash accommodates firmware, calibration tables, and communication stacks. Placing the MCU beside an analog front end shortens the data path from acquisition to USB transfer. A practical design must preserve USB signal integrity, provide correct bus-power and device-power routing, and confirm which USB host or device functions are required by the selected configuration.
おすすめ
Human-Machine Interface Controller
The LPC4323JET100E can serve as the central controller for an embedded human-machine interface combining an LCD, touch controls, communications, and application logic. The LCD interface allows display traffic to be handled locally, while the 204 MHz Cortex-M4 core leaves capacity for menu logic, graphics updates, and protocol processing. The Cortex-M0 coprocessor is useful for periodic input scanning or background communication without burdening the main processor. Its 512 KB flash and 136 KB SRAM provide more local capacity than a basic microcontroller, reducing the need for external memory in display-centric products. The BGA layout also demands careful escape routing, continuous ground planes, and proper decoupling around both processor and display-interface supplies.
おすすめ
Networked Embedded Controller
The LPC4323JET100E supports networked embedded controllers that combine local real-time control with Ethernet-based communication. The Cortex-M4 core can handle application logic and Ethernet protocol processing, while the Cortex-M0 coprocessor can execute an independent monitoring or control routine. Ethernet MAC provides the interface foundation for a connected product, and the dual high-speed USB ports add a configuration or service path without requiring another controller. With 512 KB of flash and 136 KB of SRAM, the device can host substantial network and control firmware locally. A production board should isolate Ethernet magnetics and analog transceiver sections, use controlled-impedance routing, provide clean supply rails, and test EMC performance under realistic cable and load conditions.
おすすめ
High-Speed USB Interface Appliance
The LPC4323JET100E is well matched to USB interface appliances that move data between a host, peripheral sensors, and embedded processing logic. Two high-speed USB interfaces allow one connection to be reserved for the upstream host while another manages an internal peripheral relationship. The 204 MHz Cortex-M4 core handles throughput-oriented protocol and data tasks, and the Cortex-M0 coprocessor can offload service, status, or monitoring activity. Local 136 KB of SRAM helps avoid immediate off-chip memory access during short data bursts, while 512 KB of flash supports stack and application firmware. Layout should include short USB routing, continuous reference planes, correct connector launch geometry, and separate filtering strategies for each interface.
おすすめ
Secure Embedded Processing
The LPC4323JET100E can anchor a secure embedded processing system where local control and service connectivity must coexist. The Cortex-M4 core provides the primary application-processing capacity, while the Cortex-M0 coprocessor can partition monitoring or communication tasks into an isolated execution domain supported by the device architecture. The 136 KB of SRAM and 512 KB of flash support local protocol handling, key material, device identity, and update logic. Two high-speed USB interfaces can support provisioning and operational data paths, while Ethernet MAC supports network management. Security architecture should include protected boot, authenticated firmware updates, controlled debug access, secure key provisioning, and physical assurance measures rather than relying solely on firmware isolation between the two cores.

設計ノート
Use the manufacturer’s recommended power architecture and decoupling network for the 3.3 V device. Place high-frequency bypass capacitors immediately beside the relevant power balls, maintain a low-impedance ground reference, and separate sensitive analog or transceiver supplies from digital switching paths where the design permits. Confirm the exact voltage rails and bypass requirements from the LPC4323JET100 documentation before releasing the PCB because exposed-pad and internal-supply details cannot be inferred solely from the distributor summary.
Treat the two high-speed USB interfaces and Ethernet interface as controlled-impedance, continuous-reference-plane nets. Route each high-speed differential pair over a stable ground plane, minimize vias and stubs, and keep connector launches, protection devices, and PHY or transceiver components close to the relevant balls. The 100-pin TFBGA requires careful BGA escape routing; review the manufacturer land pattern and use appropriate via-in-pad or fanout techniques only after confirming assembly capability.
The 100-pin TFBGA has a large number of ground and power connections that should be used to distribute heat and maintain electrical performance. Check the package’s exposed-pad treatment, board copper area, via pattern, and maximum assembly requirements in the NXP package documentation. Validate the final design with the expected processor, memory, Ethernet transceiver, USB circuitry, and ambient conditions because junction temperature depends on the assembled board rather than the package alone.
Do not assume that two LPC43xx devices in the same TFBGA package are interchangeable merely because their outlines match. Compare every ball assignment, power domain, analog input, USB role, Ethernet function, debug signal, clock input, and reset connection for the exact ordering code. The LPC4370FET100E comparison, for example, identifies 64 KB of ROM versus the LPC4323JET100E configuration with 512 KB of flash, demonstrating why feature-level verification is essential.
コンプライアンス情報
Compliance status requires confirmation from the current NXP product documentation or a material declaration for the exact ordering code.
