The Flexcomm peripheral lets you repurpose serial pins as I2C, SPI, or UART without changing the PCB — useful when a last-minute BOM swap requires a different protocol. USB OTG adds host/device capability, so the same MCU can act as a USB flash-drive reader for firmware updates or as a peripheral to a PC for data logging.
Yes, the LPC55S66JBD64K includes USB connectivity with OTG support.
The LPC55S66JBD64K is rated for -40 to 105 °C ambient operating temperature.
Yes, the supply range is 1.8 V to 3.6 V, so it works on a 1.8 V rail.
