Product details

USB connectivity and peripheral mix

The USB device controller is the main differentiator from the base LPC11 parts — the LPC11U24FBD64/401, includes I²C, SPI, SSI, SSP, UART/USART, and Microwire alongside USB, making it a single-chip bridge between legacy serial buses and a USB host. The 8-channel 10-bit ADC (A/D 8x10b) covers analog inputs like potentiometers or temperature sensors without an external converter. Internal oscillator means no external crystal needed for USB timing, saving two pins and board area.

NXP has marked the LPC11U24FBD64/401 as Obsolete. No official successor order code is listed.

Frequently asked questions

What is the replacement for LPC11U24FBD64/401?

No official NXP replacement is listed. The LPC11U24FBD64/301 variant shares the same package and memory but has a different USB configuration — verify USB feature compatibility before substituting.

Does LPC11U24FBD64/401 have USB support?

Yes, it includes a full-speed USB 2.0 device controller with support for I²C, SPI, UART/USART, and other serial interfaces.

What is the pinout of LPC11U24FBD64/401?

The pinout follows the standard 64-LQFP (10x10 mm) footprint for the LPC11U24 family. The 54 I/O include USB D+/D-, serial interface pins, and ADC inputs. Download the datasheet PDF for the full pin assignment table.

What is LPC11U24FBD64/401's listed speed?

The core runs at 50 MHz, which is the maximum clock for the ARM Cortex-M0 in this device.
