Product details

Where it fits — industrial control, USB peripherals, and IoT edge nodes

The USB device controller supports direct PC connection for firmware updates and data streaming, while the 50 MHz Cortex-M0 handles protocol parsing and control loops without an external host processor.

50 MHz Cortex-M0 — what the speed buys you

50 MHz Cortex-M0 handles USB full-speed data transfers and application code. 10 KB SRAM buffers USB packets; 4 KB EEPROM stores calibration constants.

For single-unit prototyping or small-batch production, we can provide a competitive quote — no minimum order quantity restrictions apply.

Frequently asked questions

Where can I buy LPC11U37FBD48/401 and get a price?

The LPC11U37FBD48/401 is available to order through our independent distribution channel. Submit an RFQ for current pricing and availability — no minimum quantity required.

Does LPC11U37FBD48/401 support USB programming and debugging?

Yes, the USB device controller supports programming and debugging via the on-chip ROM bootloader. No external programmer is needed for field firmware updates over USB.

What is the difference between LPC11U37FBD48/401 and /301?

The LPC11U37FBD48/401 includes 4 KB of EEPROM; the /301 variant omits the EEPROM block. Both share the same pinout, Flash, RAM, and peripheral set, so the /301 is a drop-in replacement if EEPROM is not required.

Does LPC11U37FBD48/401 support USB host or OTG?

No, this part includes a full-speed USB 2.0 device controller only. USB host or OTG capability is available in the larger LPC11U6x and LPC18xx families.

Where can I download the LPC11U37FBD48/401 datasheet?

The datasheet is available from NXP's website or through our product page. Contact us for a direct link or document copy.
