LPC1812JET100E - 180MHz Cortex-M3 512KB MCU | NXP
부품 번호: LPC1812JET100E ✓ 활성LPC1812JET100E 개요
An ARM Cortex-M3 microcontroller is a 32-bit embedded processor within the microcontroller and semiconductor hierarchy. The Cortex-M3 architecture uses a simplified instruction set and Thumb-2 technology to balance processing performance, deterministic interrupt handling, and low implementation complexity. Within the NXP LPC18xx family, the LPC1812JET100E is positioned as a high-performance MCU with 512 KB of program flash and 104 KB of SRAM, while retaining the peripheral and software ecosystem associated with the LPC18xx product line.
Three principal characteristics define the part. Its 180 MHz operating frequency supports compute-intensive embedded workloads, while 512 KB of flash provides room for application code, firmware, and embedded data. The 104 KB of SRAM reduces dependence on external memory for working data and buffers. Its 100-ball TFBGA package, identified by the verified distributor data as a 9 mm by 9 mm package, supports compact designs but requires a fine-pitch PCB layout and careful manufacturing control.
The Cortex-M3 architecture provides a 32-bit processing platform with efficient exception handling and low-power features intended for embedded use. The exact peripheral mix, clock configuration, I/O ratings, and electrical limits must be confirmed against the LPC1812JET100 manufacturer datasheet before final schematic or firmware sign-off. The supplied NXP product information identifies the MCU as a high-performance Cortex-M3 device and confirms the 512 KB flash, 104 KB SRAM, 180 MHz operating point, and TFBGA100 package used in this product record.
Typical uses for the LPC1812JET100E include industrial data acquisition, communications equipment, USB-connected products, human-interface systems, and embedded control platforms with moderate code-storage requirements. Its 512 KB flash is useful for protocol stacks and application firmware, while 104 KB SRAM can support packet buffers, display interfaces, or multiple communication tasks. The 180 MHz Cortex-M3 core is particularly relevant when software timing, protocol handling, and control-loop calculations must coexist in one compact device.
Designers should treat the fine-pitch TFBGA footprint as a manufacturing-sensitive implementation point. PCB layout must follow the NXP package drawing, including ball assignments, power routing, decoupling placement, and thermal-via requirements. Because the verified excerpts do not publish complete pin assignments, timing diagrams, or absolute maximum ratings, those values should be taken directly from the official datasheet rather than inferred from the distributor summaries.
This product record combines verified manufacturer and distributor information with package-aware alternatives, practical PCB guidance, and direct answers to common sourcing and engineering questions. It is intended to accelerate component selection while clearly separating confirmed LPC1812JET100E facts from parameters that still require datasheet-level verification.

일반적인 애플리케이션
LPC1812JET100E 적합 용도: 6 애플리케이션s: Industrial Data Acquisition Controller, USB Communications Gateway, Human-Interface and Control Terminal, Networked Embedded Control Node, USB-C Powered Embedded Product, Consumer and Wearable Controller.
Industrial Data Acquisition Controller
The LPC1812JET100E fits industrial acquisition equipment that combines protocol processing with local control. Its confirmed 180 MHz Cortex-M3 core provides processing headroom for sampling loops, filtering, and communications, while 512 KB of flash can hold firmware and configuration data. The 104 KB of SRAM is useful for sample buffers and protocol state. A design can place the MCU beside external sensing and communication circuits, subject to verification of the exact ADC, timer, and interface resources in the NXP datasheet. The -40 °C to +105 °C rating supports industrial-temperature environments, but EMC, grounding, isolation, and watchdog design remain important for dependable factory operation.
추천
USB Communications Gateway
The LPC1812JET100E is appropriate for a compact communications gateway that manages USB-facing data and an embedded protocol stack. Its 512 KB flash provides useful local storage for firmware, configuration tables, and USB descriptors, while 104 KB of SRAM can support receive buffers and protocol state. The 180 MHz Cortex-M3 core can process framing, routing, and diagnostic tasks efficiently. Because the verified excerpt does not confirm the exact USB controller configuration for this MPN, the implementation must verify host or device capability, pin multiplexing, and transceiver requirements in the official datasheet before routing the USB interface or selecting connector hardware.
추천
Human-Interface and Control Terminal
The LPC1812JET100E can serve as the central controller in a human-interface terminal that coordinates display updates, keypad input, indicators, and local control logic. The 180 MHz Cortex-M3 core allows interface tasks to coexist with application code, while 512 KB flash and 104 KB SRAM reduce pressure on external storage. The TFBGA100 package also supports compact multi-function products when PCB area is constrained. Engineers should verify available display, serial, timer, and GPIO assignments in the exact device data sheet, and should use the manufacturer ball map to ensure that display and control signals are routed to pins that support the selected peripheral function.
추천
Networked Embedded Control Node
The LPC1812JET100E fits an embedded control node that combines local deterministic control with network communication. The confirmed 512 KB flash can accommodate a protocol stack and application firmware, and 104 KB of SRAM supports connection state and message buffering. At 180 MHz, the Cortex-M3 core can process multiple communication and control tasks while maintaining predictable interrupt-driven behavior. For networked designs, confirm Ethernet MAC, PHY interface, package-ball availability, and clock requirements from the NXP data sheet. A companion Ethernet PHY may be required, and its reference design and decoupling requirements should be followed to avoid signal-integrity and power-supply problems.
추천
USB-C Powered Embedded Product
The LPC1812JET100E can support a compact USB-powered embedded product when the device must combine application processing, communications, and local control. Its 180 MHz Cortex-M3 core provides processing capacity without an external processor, while 512 KB flash and 104 KB SRAM accommodate firmware and working data. The principal engineering tradeoffs are heat generation, power-rail sequencing, and the density of the 100-ball TFBGA layout. Power budgeting should include both the MCU and any Ethernet, USB, or transceiver circuitry. If a USB-C interface is used, the system also needs the appropriate receptacle, protection, configuration-channel logic, and verified routing that is independent of the MCU's package constraints.
추천
Consumer and Wearable Controller
The LPC1812JET100E is suitable for a feature-rich consumer or wearable controller that requires more storage and processing than a basic microcontroller provides. The 512 KB flash can hold larger application code, and 104 KB of SRAM supports buffered sensor, display, or wireless data. The 180 MHz Cortex-M3 core helps maintain responsive user-interface and control tasks. Its -40 °C to +105 °C rating covers many portable-device ambient conditions, although battery-powered use requires careful attention to average current, standby behavior, and regulator efficiency. Because exact low-power mode and GPIO current specifications are absent from the verified excerpts, those values must be checked in the manufacturer datasheet before battery sizing.

설계 노트
Use the official NXP TFBGA100 land pattern and ball map without substituting a generic 100-ball BGA pattern. Keep decoupling capacitors close to the relevant supply balls, provide an uninterrupted return path beneath the device, and follow the manufacturer's PCB-stackup, via, solder-mask, and assembly recommendations. The verified package is 9 mm by 9 mm, but its individual ball functions and exposed thermal requirements are not present in the supplied excerpts, so PCB release must be checked against the current datasheet.
Calculate the complete power budget rather than considering only the 180 MHz operating point. Estimated: MCU dissipation depends on supply voltage, active-versus-idle duty cycle, peripheral loading, and clock configuration, none of which are specified in the supplied excerpts. Prototype worst-case thermal and current measurements, then confirm the regulator's current capability and transient response against the complete board load. Do not size the power path from the Cortex-M3 frequency alone.
Route clock, debug, and communication interfaces according to the NXP reference design and the exact selected peripheral mux. Fine-pitch BGA escape routing can create coupling between adjacent nets, so maintain manufacturer-recommended spacing and via geometry. If Ethernet or high-speed USB is used, preserve the required reference-controlled impedance and keep the external PHY, connector, protection, and decoupling components close to their associated device pins.
Do not treat a shared LPC18xx JET100 package suffix as proof of complete drop-in equivalence. The LPC1837JET100E, LPC1827JET100E, LPC1823JET100E, and LPC1822JET100E candidates require separate review of flash, SRAM, CPU frequency, Ethernet, USB, peripheral availability, pin multiplexing, and startup behavior. Before substituting any candidate, compare the official ball tables and errata, rebuild affected firmware initialization, and perform hardware regression testing on the intended production PCB.
규정 준수 정보
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for LPC1812JET100E. These fields remain unknown rather than being inferred from the manufacturer or product family.
