This application note describes how to use I3C on LPC86x. It mainly includes the basic knowledge of I3C, the introduction of I3C peripherals of LPC86x, and the introduction of I3C SDK routines.

LPC86x is an Arm Cortex-M0+ based, low-cost, 32-bit MCU family operating at CPU frequencies of up to 60 MHz. LPC86x supports up to 64 kB of flash memory and 8 kB of SRAM. The peripheral complement of LPC86x includes a CRC engine, one I²C -bus interface, one I3C-MIPI bus interface, up to three USARTs, up to two SPI interfaces, one multi-rate timer, one self-wake-up timer, two FlexTimers, one DMA, one 12-bit ADC, one analog comparator, function-configurable I/O ports through a switch matrix, one input-pattern match engine, and up to 54 general-purpose I/O pins.
