The LPC2880/LPC2888 are an ARM7-based microcontroller for portable applications requiring low power and high performance. It includes a USB 2.0 Hi-Speed device interface, an external memory interface that can interface to SDRAM and flash, an SD/MMC memory card interface, A/D and D/A converters, and serial interfaces including UART, I2C-bus, and I2S-bus. Architectural enhancements like multi-channel DMA, processor cache, simultaneous operations on multiple internal buses, and flexible clock generation help ensure that the LPC2880/LPC2888 can handle more demanding applications than many competing devices. The chip can be powered from a single battery, from the USB, or from regulated 1.8 V and 3.3 V.
