[1] The following applies to Table 5:
a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless
otherwise noted.

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.
