LPC3180/01 Device

A USB OTG interface with full host capability lets this high-performance

microcontroller connect directly to peripherals. Other options –

including seven UARTs, two SPI, two I

C, a real-time clock with

separate power domain, and controllers for NAND Flash and SDRAM

memory – increase design ﬂexibility.

KEY FEATURES
