LPC1825JET100E - 180MHz Cortex-M3 MCU | NXP | Embedded
Артикул: LPC1825JET100E ✓ АктивенLPC1825JET100E Обзор
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, peripherals, and communication interfaces onto one package. Within the embedded-system hierarchy, the LPC1825JET100E belongs to the Arm Cortex-M3 MCU class and combines a 32-bit RISC processor with USB, Ethernet-oriented connectivity options, and other peripherals designed for industrial, communications, and human-interface applications. This integration reduces the number of discrete components required around the central controller.
The principal memory features are 768 KB of flash and 136 KB of SRAM, while the processor operates at up to 180 MHz. USB support adds a practical connection option for firmware update, device-to-host communication, or peripheral integration. The 100-ball TFBGA package supports compact assemblies but requires careful PCB layout because its fine ball pitch and exposed thermal-management requirements make the footprint more demanding than a leaded package.
The LPC1825JET100E is positioned as a high-performance Cortex-M3 device for embedded applications that need more memory and connectivity than a basic microcontroller. Its 768 KB flash capacity provides room for a larger embedded code base, while 136 KB of SRAM supports working memory, buffers, networking structures, and real-time control data. The 180 MHz operating speed also provides additional compute headroom for control loops, protocol processing, and user-interface logic.
Typical applications include industrial control equipment, USB-connected data acquisition, communications infrastructure, connected sensors, and compact embedded controllers. A design can place the MCU at the center of a control board, using its SRAM for active data, flash for firmware, and USB for configuration or host connectivity. Peripherals should be assigned according to the complete NXP pin description so that signal multiplexing and board-level interfaces remain deterministic.
The main design consideration is package implementation. A 100-pin TFBGA is intended for multilayer PCB manufacturing, and its escape routing, via placement, solder-mask design, and thermal layout must follow the package drawing. Place decoupling capacitors adjacent to the appropriate supply pins, preserve the prescribed via pattern, and verify the PCB stack-up and assembly process before releasing a production design.
This product page combines the manufacturer identification, verified distributor specifications, memory and package details, application guidance, and replacement analysis. It also distinguishes direct same-package options from broader functional comparisons so engineers can identify which substitutions require a board-level redesign before making a sourcing decision.

Типичное применение
LPC1825JET100E подходит для 6 применениеs: Industrial Control Systems, USB Data Acquisition, Connected Sensor Hubs, Communications Infrastructure, Human Interface Controllers, Compact Embedded Gateways.
Industrial Control Systems
The LPC1825JET100E fits compact industrial controllers that require a 180 MHz Arm Cortex-M3 core, 768 KB of flash, and 136 KB of SRAM. The processor supports deterministic control tasks while the SRAM accommodates control state, buffers, and communications structures. Its 3.3 V operation and USB connectivity can simplify configuration or service connections. A production design should assign functions from the complete NXP pin-description table and validate timing, isolation, and environmental requirements for the target installation.
Рекомендуется
USB Data Acquisition
The LPC1825JET100E is appropriate for data-acquisition equipment that combines a 32-bit Cortex-M3 processor with USB connectivity. The 768 KB flash provides room for acquisition firmware and configuration tables, while 136 KB of SRAM supports sample buffers and protocol processing. At up to 180 MHz, the core can service control and data-transfer logic. The TFBGA implementation requires a multilayer PCB, and USB routing should be reviewed against the manufacturer layout guidance to limit signal-integrity risk.
Рекомендуется
Connected Sensor Hubs
The LPC1825JET100E can serve as the central processor in a connected sensor hub where local buffering and network-facing firmware are important. Its 136 KB of SRAM offers space for sensor data, network structures, and working variables, while 768 KB of flash supports the application and configuration layer. USB provides a service or host interface when required by the architecture. Pin multiplexing, clock planning, and low-power behavior should be selected from the manufacturer configuration tables rather than assumed from the family designation.
Рекомендуется
Communications Infrastructure
The LPC1825JET100E suits communications equipment requiring a high-performance Cortex-M3 core, substantial flash, and working SRAM. Its 180 MHz operating rate provides compute capacity for protocol handling and control, while the 136 KB SRAM can hold active packet structures and buffers. Ethernet and USB capabilities make it useful in gateways, interface modules, and service equipment. The design should confirm the required MAC, PHY, connector, and timing implementation against the exact device configuration and manufacturer reference material.
Рекомендуется
Human Interface Controllers
The LPC1825JET100E can support touch, display, and keypad-oriented human interface controllers because its Cortex-M3 core provides more processing headroom than a basic controller. The 768 KB flash accommodates graphics or interface firmware, and 136 KB of SRAM supports screen buffers, input handling, and application state. LCD capability is identified for the LPC18xx family, but the exact target configuration must be checked in the NXP pin and peripheral documentation. External display interfaces also require careful signal routing from the fine-pitch TFBGA.
Рекомендуется
Compact Embedded Gateways
The LPC1825JET100E is well matched to compact gateways that need local protocol processing and flexible connectivity in a 9 x 9 mm TFBGA footprint. Its 180 MHz Cortex-M3 core handles gateway logic, 768 KB of flash stores firmware and configuration data, and 136 KB of SRAM supports active protocol state. Ethernet and USB enable upstream and service connectivity. Thermal, via-pattern, and escape-routing compliance with the NXP package guidance is essential because the compact package concentrates routing and power requirements in a small board area.

Заметки по проектированию
Treat the 100-pin TFBGA as a fine-pitch surface-mount design and follow the NXP package drawing for land patterns, ball assignments, and via requirements. Place board escapes directly beneath the device where practical, maintain the recommended via geometry, and validate the design against the PCB manufacturer's assembly capability. Recheck every ball assignment because several LPC18xx peripheral signals are multiplexed.
Plan the 3.3 V power distribution so that supply and ground connections have low impedance between the PCB and the TFBGA balls. Place the required input and internal decoupling capacitors close to their designated supply pins and route high-current returns without narrow necks. Use the NXP pin description and recommended application circuit to determine which capacitors are required, since changing the power topology without changing the physical placement can create dynamic-voltage problems.
Give USB, Ethernet, clock, and other high-speed interfaces continuous reference planes and route them away from noisy switching paths. Keep the device's escape routes short, observe the manufacturer's recommended layer transitions, and inspect the final board for impedance consistency. Although the MCU can operate at 180 MHz, peripheral timing and signal quality depend on the complete board implementation rather than the core frequency alone.
Do not treat every LPC18xx orderable member as an interchangeable pinout. The LPC1833JET100E is a same-family candidate, but its flash, SRAM, Ethernet, USB, and peripheral configuration must be reconciled with the LPC1825JET100E datasheet. A valid substitution also requires checking startup, debug pins, power pins, clock configuration, firmware memory assumptions, and PCB ball mapping before production use.
Информация о соответствии
The available manufacturer and distributor records do not state the target's RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These properties must be confirmed from the current NXP product documentation before making a compliance claim.
