LPC11E67JBD48K - 32-Bit 50MHz Cortex-M0+ MCU | NXP
料号： LPC11E67JBD48K ✓ 量产中LPC11E67JBD48K 概述
A microcontroller is an integrated circuit containing a processor core, program Flash, data memory, peripherals, and interface logic on one semiconductor device. The ARM Cortex-M0+ core provides a compact instruction set and deterministic embedded-control architecture. Within the product hierarchy, the LPC11E67JBD48K is an ARM-based microcontroller, an embedded processor, and a semiconductor intended for cost-sensitive control applications.
The LPC11E67JBD48K combines a maximum 50 MHz operating frequency with 128 KB of Flash organized as 128K x 8. This combination supports firmware storage while avoiding the memory cost and board area of a larger microcontroller package. The 48-LQFP 7 x 7 mm package offers a surface-mount solution with a comparatively compact body, although its lead pitch must be accommodated by the PCB land pattern and assembly process.
The LPC11Exx family also includes devices with up to 256 kB Flash, 36 kB SRAM, and 4 kB EEPROM according to the verified datasheet listing. A 12-bit ADC is identified in the same source. Device-specific ADC, SRAM, EEPROM, clock, and peripheral details must be confirmed in the manufacturer datasheet before assigning pins or calculating firmware resource requirements.
Typical uses for this microcontroller class include compact industrial controllers, building and access-control equipment, appliance controls, sensing nodes, and low-cost embedded products. The 50 MHz Cortex-M0+ performance is useful for responsive control loops and moderate protocol handling, while the 128 KB Flash capacity allows application firmware and configuration data to be stored locally.
Designers should verify the exact LPC11E67JBD48 pin assignments, peripheral multiplexing, clock limits, decoupling requirements, and exposed-pin treatment in the NXP datasheet. The verified web results do not provide a complete public pin table, so this record does not infer pin names or provide a fabricated package diagram mapping. PCB design and firmware bring-up should also account for the LQFP lead geometry rather than a leadless QFN footprint.
This product record combines current NXP lifecycle information, distributor inventory and pricing evidence, family-level technical data, strict data-availability markers, and procurement guidance. It distinguishes verified device facts from parameters that still require confirmation, helping engineers avoid treating broader LPC11Exx family capabilities as guaranteed LPC11E67JBD48K specifications.

典型应用
LPC11E67JBD48K 适用于 6 应用s: Industrial Equipment Controller, Building and Access Control, Appliance Control, Battery-Powered Sensing Node, Security and Surveillance Peripheral, Low-Cost Data Acquisition Module.
Industrial Equipment Controller
The LPC11E67JBD48K fits compact industrial equipment controllers that require a responsive 32-bit processor without the cost of a higher-performance MCU. Its Arm Cortex-M0+ core operates up to 50 MHz, while 128 KB of Flash stores control firmware, calibration tables, and configuration data. The 48-LQFP 7 x 7 mm package supports conventional surface-mount assembly and provides enough physical board area for accessible routing and inspection. Before committing to it, engineers must confirm the required UART, SPI, I2C, timer, ADC, logic-level, and isolation requirements in the exact device datasheet. In an industrial design, input protection, surge handling, grounding, environmental margins, and safe behavior during firmware faults may dominate controller selection.
Building and Access Control
The LPC11E67JBD48K is appropriate for access-control readers, credential gateways, and compact building-control nodes where deterministic embedded processing and local firmware are useful. Its 32-bit Cortex-M0+ architecture can execute communication handling, keypad or credential processing, event logging, and actuator-control tasks at up to 50 MHz. The verified 128 KB Flash capacity provides room for application code and persistent configuration within the MCU. The 48-LQFP 7 x 7 mm package avoids a larger leadless footprint but requires a conventional LQFP land pattern. Security-critical installations should add validated authentication, secure boot, protected keys, tamper response, and applicable building-code controls because those capabilities are not established by the supplied verification data.
Appliance Control
The LPC11E67JBD48K can serve as the primary embedded controller in a compact appliance by combining a 50 MHz Cortex-M0+ processor with 128 KB of local program Flash. It is suitable for coordinating motor or valve commands, monitoring switches or sensors, driving indicators, and maintaining a user interface, subject to exact peripheral and electrical verification. A linear regulator, sensor conditioning, and actuator drivers remain external design elements rather than functions established by the supplied data. Compared with an 8-bit controller, the 32-bit architecture provides more headroom for structured drivers, diagnostics, and multi-protocol tasks while retaining a cost-oriented MCU position. Production firmware should include watchdog recovery, brownout-aware initialization, and safe output states during startup or fault conditions.
Battery-Powered Sensing Node
The LPC11E67JBD48K can form the processing core of a compact battery-powered sensor node when the application benefits from 32-bit control and 128 KB of Flash without requiring a large application processor. It could supervise periodic measurements, preprocess data, manage communications, and record events, although the supplied sources do not specify sleep currents or wake-up timing for this exact MPN. Those values must be confirmed before calculating battery life, because average consumption often depends more on idle-state behavior and duty cycle than on peak processing frequency. The 48-LQFP package is compact at 7 x 7 mm but may be larger than the smallest QFN options. Final selection should compare verified sleep current, active current, analog performance, and regulator efficiency.
Security and Surveillance Peripheral
The LPC11E67JBD48K is a plausible controller for a low-cost security peripheral that coordinates sensors, communication, status indication, and local event handling. The 50 MHz Arm Cortex-M0+ core provides enough throughput for modest protocol and control tasks, and 128 KB Flash can hold embedded firmware without an external program-memory device. The compact 48-LQFP 7 x 7 mm package is practical for a dedicated peripheral board. However, none of the supplied evidence verifies hardware cryptographic acceleration, secure key storage, isolated communications, or a security certification level. Designs in surveillance, access control, or alarm products should therefore add the required cryptographic and tamper-resistance functions and verify them independently rather than inferring them from the processor core.
Low-Cost Data Acquisition Module
The LPC11E67JBD48K can support a compact data-acquisition module when the required measurement resolution and interface speed fit the device's verified capabilities. The family datasheet listing identifies a 12-bit ADC, but the exact LPC11E67JBD48K channel count, sampling characteristics, input range, and acquisition mode require confirmation from the manufacturer datasheet. The 32-bit processor can calculate calibration offsets, filter samples, and frame results for a host interface, while 128 KB Flash stores application code and calibration constants. The 48-LQFP package provides a manageable surface-mount footprint but is not the smallest option. A robust implementation must also account for analog grounding, reference-voltage stability, input protection, calibration, and error reporting across the full operating-temperature range.

设计说明
Treat the LPC11E67JBD48K as a 48-LQFP footprint, not a QFN. The verified package is 7 x 7 mm with leads on all four sides, so the PCB land pattern, solder-paste apertures, assembly stencil, and courtyard must follow the NXP package drawing. Keep sensitive analog and communication routes away from fast-switching nodes where practical. Because the supplied data does not include the pin table, do not assign power, ground, oscillator, reset, or I/O nets from memory; freeze the schematic pin mapping only after checking the exact LPC11E67JBD48 documentation.
Confirm the exact device supply-voltage limits and pin-specific decoupling requirements in the manufacturer datasheet before selecting regulators and capacitors. A practical low-noise layout should place the required input capacitors directly beside their associated supply and ground pins, provide a low-impedance ground return, and isolate sensitive analog routing from switching supplies. Estimated power consumption should not be calculated from the 50 MHz maximum alone; it depends on the selected clock, active versus sleep states, peripheral loading, and output drive. The supplied sources do not provide current-consumption figures, so those values remain design-review items.
Do not treat every LPC11Exx family maximum as a guaranteed LPC11E67JBD48K feature. The verified family sources mention up to 256 kB Flash, 36 kB SRAM, 4 kB EEPROM, and a 12-bit ADC, while the exact device listing confirms 128 KB Flash. Validate the ordering suffix, temperature grade, SRAM, EEPROM, ADC channels, communications peripherals, and timers against the manufacturer data before writing firmware. A common error is assuming that another manufacturer's Cortex-M0+ MCU is interchangeable merely because its core instruction set is similar.
合规信息
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields must be confirmed using the exact LPC11E67JBD48K orderable-part documentation or supplier declarations.
