The NXP LPC1115FET48/303QL is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100XL series, clocked at 50 MHz. The 64 KB Flash and 8 KB RAM support a single control loop with a communications stack.
The peripheral set includes I²C, SPI, and UART/USART for sensor buses and serial displays, plus brown-out detect and a watchdog timer for unsupervised operation.
The LPC1100XL series offers pin-compatible density variants in the same 48-TFBGA footprint — for example, the 32 KB Flash / 4 KB RAM option (LPC1114FET48/303) or the 128 KB Flash / 12 KB RAM option (LPC1115FET48/303QL is already the 64 KB Flash mid-range). All share the same peripheral set and 50 MHz core speed, so a firmware migration is a linker-script change, not a board spin.
The core processor runs at 50 MHz, which is the maximum clock speed for the LPC1100XL series ARM Cortex-M0.
