Highlighted here are the values and the differentiating features provided by the LPC51U68 MCU. First, the Cortex®-M0+ high performance capabilities for power conscious designs. The LPC51U68 MCU pushes the performance of the Cortex-M0+ to 100MHz, which is more than 2x faster than current Cortex-M0+ based products. Secondly, developers can benefit from the extended memory resources, including 96kB of on-chip SRAM and 256kB of on-chip flash programming memory with flash accelerator. NXP’s LPC51U68 microcontroller also features unparalleled design flexibility and integration, including a USB 2.0 full-speed device controller supporting crystal-less operations and eight flexible serial communication peripherals, each of which can be enabled as USART, SPIs, or I²C interfaces. Two Flexcomm interfaces also include an I²S interface, for a total of 2 channel pairs. The LPC51U68 MCU devices are pin-function compatible with LPC5410x and LPC5411x MCU families in the same packages and pinout versions. The LPC51U68 is supported by NXP’s MCUXpresso Software and Tools ecosystem – which comes with an IDE, SDK, and a configuration tool.
