The 32 KB Flash holds the application code and can be programmed in-system via the USB or UART bootloader, which simplifies field updates when the design allows a firmware-reprogramming cycle.
Brown-out detect and POR blocks hold the core in reset until the rail is stable.
This makes it a safe choice for new BOM entries and ongoing production runs requiring USB connectivity in a small 32-pin package.
The supply voltage range is 1.8 V to 3.6 V, allowing single-rail operation from a 3.3 V regulator or a 2-cell battery.
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Within the LPC11Uxx series, higher-density variants (e.g., 64 KB Flash / 8 KB SRAM) share the same 32-HVQFN footprint and pinout, providing a drop-in upgrade path for firmware growth.
The part is listed with RoHS compliance as standard for NXP's LPC11Uxx series in the HVQFN package.
