Overview

The LPC11U67JBD48E is a 32-bit ARM Cortex-M0+ microcontroller from NXP designed for entry-level USB applications. Operating at up to 50MHz, it integrates 128KB of Flash, 20KB of RAM, and 4KB of on-chip EEPROM in a compact 48-pin LQFP package. The device features 5V tolerant I/O and low-power modes, making it suitable for modern industrial and consumer peripheral designs.

Why Choose This Part

The LPC11U67JBD48E offers a significant upgrade in power efficiency by using the Cortex-M0+ core, which consumes as little as 1.5mA at 12MHz in low-current mode. It features 5V tolerant pins for easier integration into mixed-voltage systems and provides integrated EEPROM for non-volatile configuration storage without external components.

Applications

USB HID Devices
The integrated USB 2.0 full-speed controller and flexible I/O make it ideal for computer peripherals such as keyboards, mice, and game controllers.
Industrial Sensing
Utilizes the on-chip temperature sensor, 12-bit ADC, and 4KB EEPROM for local data logging and environmental monitoring.
Battery-Powered Instrumentation
Low-power modes including deep-sleep and power-down allow for extended battery life in portable measurement tools.
Communications Bridges
Multiple serial interfaces including I2C, SPI, and UART allow the device to act as a bridge between USB and legacy industrial protocols.
