Supply and temperature range
Operates on a 1.8 V to 3.6 V supply. The -40 to 85 °C industrial temperature grade suits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics where ambient heat stays below 85 °C.

Operates on a 1.8 V to 3.6 V supply. The -40 to 85 °C industrial temperature grade suits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics where ambient heat stays below 85 °C.
The supply range is 1.8 V to 3.6 V, covering both 3.3 V and 1.8 V logic rails.
The LPC1100XL family includes pin-compatible density variants (LPC1111, LPC1112, LPC1114) in the same 32-HVQFN footprint, allowing a straightforward BOM swap if memory requirements change.
The core runs at 50 MHz, which is the maximum clock frequency for this ARM Cortex-M0 device.
The datasheet is published by NXP under the LPC111X/LPC11CXX series documentation. A PDF download is available from the manufacturer's website or through the storefront's document link.
