Preliminary data sheet

1. General description

The LPC2880/2888 is 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 ï¬ash, an SD/MMC memory

card interface, ADC and DACs, 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 ï¬exible clock generation help

ensure that the LPC2880/2888 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.

2. Features
