LPC11U67JBD48E - 50MHz 128KB Flash MCU | NXP | USB Cortex-M0+
MPN: LPC11U67JBD48E ✓ AktifLPC11U67JBD48E Ringkasan
The LPC11Uxx family belongs to the microcontroller hierarchy: MCU > embedded processor > Arm Cortex-M0+ microcontroller > low-power embedded control. The Cortex-M0+ architecture provides a simple instruction set and efficient code density while retaining a 32-bit processing model. At up to 50MHz, the LPC11U67JBD48E is suitable for connected peripherals, human-interface systems, sensor controllers, and compact consumer or industrial equipment.
Verified listings identify 128KB Flash, 20KB SRAM, USB, and a 12-bit ADC. The 48-LQFP (7x7) package provides a conventional leaded footprint that can simplify assembly and prototyping compared with a fine-pitch ball grid array. The 2.4V to 3.6V operating range supports common 3.3V system rails, although the complete electrical limits must be confirmed in the manufacturer datasheet before final design release.
The USB capability makes the device useful for USB-to-serial adapters, configuration interfaces, HID peripherals, data acquisition controllers, and service ports. Its ADC supports applications that monitor analog sensors or industrial inputs without requiring a separate converter. The combination of 128KB Flash and 20KB SRAM gives embedded software room for protocol stacks, control logic, buffers, and application code.
A typical design places the MCU beside its USB connector, 3.3V regulator, decoupling capacitors, crystal or clock source, and application peripherals. Keep USB differential routing short, controlled-impedance, and away from noisy switching nodes. Confirm oscillator, reset, USB, and peripheral pin assignments against the official datasheet before PCB routing. This page combines verified distributor specifications, sourcing information, application guidance, and same-footprint alternatives for engineering evaluation.

Aplikasi Umum
LPC11U67JBD48E cocok untuk 6 aplikasis: USB-to-Serial Interface, USB HID Control Panel, Industrial Sensor Controller, Data Acquisition Module, Battery-Powered Portable Accessory, Connected Equipment Configuration Port.
USB-to-Serial Interface
The LPC11U67JBD48E fits a USB-to-serial bridge because its Cortex-M0+ core runs up to 50MHz while the device provides 128KB Flash, 20KB SRAM, and USB connectivity. Firmware can implement a USB communication class, command parser, and serial data path in the 48-LQFP package. The 2.4V to 3.6V range supports a 3.3V rail, although USB signal-routing, connector protection, and driver compatibility must be validated separately before production.
Direkomendasikan
USB HID Control Panel
The LPC11U67JBD48E is suitable for a compact USB human-interface-device panel because the verified feature set includes USB, a 50MHz Cortex-M0+ processor, and ample code and RAM space for descriptor handling, debouncing, and status reporting. Its 48-LQFP footprint is practical for through-hole-compatible prototype assembly. Developers should reserve direct access to USB data lines, implement ESD protection, and verify enumeration behavior against the intended operating system and host configuration.
Direkomendasikan
Industrial Sensor Controller
The 12-bit ADC in the LPC11U67JBD48E supports analog measurement in a compact industrial sensor controller, while 128KB Flash and 20KB SRAM allow acquisition logic, calibration, filtering, and communications to coexist. The 50MHz Cortex-M0+ core is appropriate for responsive digital control without moving to a higher-power processor class. Exact ADC channels, sampling characteristics, and operating-temperature limits must be checked in the official datasheet before selecting sensors and analog front-end components.
Direkomendasikan
Data Acquisition Module
The LPC11U67JBD48E can act as the control and communications processor in a small data-acquisition module because it combines a 12-bit ADC, 128KB Flash, 20KB SRAM, and USB in one 48-LQFP device. The microcontroller can buffer samples, apply digital filtering, timestamp events, and expose results through a USB interface. Engineers should verify ADC input limits and acquisition timing, isolate analog and digital returns, and include input protection appropriate to the measured signal range.

Battery-Powered Portable Accessory
The LPC11U67JBD48E is a candidate for a battery-powered portable accessory when a designer values its compact 48-LQFP footprint, 3.3V-class operation, and integrated USB interface for charging or configuration. Its 50MHz Cortex-M0+ core can execute control functions efficiently, while 20KB SRAM is adequate for many embedded protocols. Low-power current, analog accuracy, battery charging requirements, and USB suspend behavior were not supplied, so a battery-life claim requires measurement from the manufacturer data and prototype testing.
Direkomendasikan
Connected Equipment Configuration Port
The LPC11U67JBD48E fits a connected equipment configuration port by using USB for service connectivity and its 128KB Flash for firmware, parameters, and communication code. The 20KB SRAM supports buffering and protocol state, while the 48-LQFP package keeps the design compact. The implementation should include controlled access to configuration data, recovery behavior after power loss, connector protection, and firmware update procedures. USB class support and device identifiers must be confirmed from the official documentation.

Catatan Desain
Place all decoupling capacitors directly between the nearest power and ground pins, with the shortest possible current-loop path. The verified data does not specify the required capacitance or ESR, so use the values and layout recommendations in the current NXP datasheet. Separate noisy analog, digital, and USB return paths where practical, and provide a continuous ground reference under the LQFP footprint where the package construction allows.
Route USB D+ and D- as a short, tightly coupled pair with matched geometry and a continuous ground reference. Keep the pair away from switching regulators, crystal lines, reset traces, and high-current switching nodes. Confirm the required routing and shielding approach from the USB implementation guidance associated with the NXP LPC11Uxx family. Do not assume that the 50MHz CPU clock can be routed through USB-like geometry.
Design the supply for the verified 2.4V to 3.6V operating range, normally using a regulated 3.3V rail where the application permits. Verify startup, brownout, sleep, and USB-suspend current from the official datasheet because these values were not included in the verified search data. Check USB transceiver and analog-peripheral supply requirements against the device's rail specifications, and avoid accidental current paths through signal pins during brownout conditions.
Do not treat a same-package related MPN as a drop-in replacement without reviewing pin names, peripheral multiplexing, memory capacity, USB support, and device identifiers. In particular, the verified data identifies LPC11U66, LPC11E67, and LPC11E68 comparison parts but does not provide complete quantitative feature differences. Rebuild or update firmware as necessary, and perform a complete bring-up test after substituting any related part.
Informasi Konformitas
RoHS compliance is shown in the verified LCSC listing. The other compliance fields were not stated in the supplied verified data and therefore remain unknown.
