Overview

The LPC11U24FBD48/401 is an ARM Cortex-M0 based 32-bit microcontroller designed for low-power applications requiring integrated USB 2.0 full-speed connectivity. It operates at speeds up to 50MHz and includes 32KB of Flash, 8KB of RAM, and 4096 bytes of on-chip EEPROM for non-volatile data storage. This MCU is notable for its ROM-based USB drivers and 32-bit integer division routines, which reduce code size and simplify development.

Why Choose This Part

This microcontroller features unique ROM-based USB drivers that save significant Flash space and ensure robust USB implementation. It offers excellent power efficiency with multiple low-power modes and includes 5V tolerant I/O pins, simplifying interfacing with legacy digital logic. The integrated EEPROM is particularly useful for storing calibration data or user settings without needing external memory chips.

Applications

USB Peripherals
Ideal for creating USB HID-class devices like keyboards or custom industrial controllers using the integrated ROM-based drivers.
Battery-Powered Handhelds
Utilizes deep-sleep and power-down modes with currents as low as 2uA to extend the life of portable equipment.
Sensor Hubs
Collects and processes data from various sensors using 40 I/Os and I2C/SPI interfaces before reporting over USB.
Consumer Electronics
Small-footprint LQFP48 package suitable for compact designs like PC gaming peripherals and smart home controllers.
