Listed as Active by NXP, so no last-time-buy clock is running. For dual-source planning, the LPC11Uxx family shares pin-compatible density options across the same HVQFN footprint — verify the Flash/RAM cut against your firmware image before substituting.
The core runs at 50 MHz, which is the maximum clock for the ARM Cortex-M0 in this device.
