Hi-Speed USB 2.0 device, and SDRAM memory interface
Rev. 03 — 17 April 2008
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 flash, an SD/MMC memory
card interface, ADC and DACs, and serial interfaces including UART, I
2
C-bus, and
I
2
S-bus. Architectural enhancements like multi-channel DMA, processor cache,
simultaneous operations on multiple internal buses, and flexible 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.
