LPC2880; LPC2888
16/32-bit ARM microcontrollers; 8 kB cache, up to 1 MB 铿俛sh,
Hi-Speed USB 2.0 device, and SDRAM memory interface
Rev. 01 鈥?22 June 2006
Preliminary data sheet
1. General description
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 铿俛sh, an
SD/MMC memory card interface, A/D and D/A converters, 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 铿俥xible 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.
