Rated for -40 to 85 °C ambient, this is the industrial temperature grade. It suits factory-floor controllers, outdoor telecom cabinets, and HVAC panels. The brown-out detect and POR peripherals are built in, so an external supervisor is optional for most designs. The internal oscillator saves a crystal on low-accuracy timing — but if you need a precise baud clock, the UART peripheral can use an external source.

Product details
Frequently asked questions
What is the exact package of LPC1114FHN33/301551?
The package is a 32-VQFN with exposed pad, supplier device package 32-HVQFN (7x7 mm).
What is the operating voltage of LPC1114FHN33/301551?
The supply voltage range is 1.8 V to 3.6 V on Vcc/Vdd.
What are the alternatives or equivalents for LPC1114FHN33/301551?
The base product number LPC1114 covers multiple Flash and RAM density options in the same 32-VQFN footprint, so a sibling density is a pin-compatible alternative if the BOM needs more memory.
