The LPC2880/2888 includes an ARM7TDMI CPU with an 8 kB cache, an AMBA AHB
interfacing to high-speed on-chip peripherals and internal and external memory, and four
AMBA APBs for connection to other on-chip peripheral functions.
The LPC2880/2888 includes a multi-layer AHB and four separate APBs, in order to
minimize interference between the USB controller, other DMA operations, and processor
activity. Bus masters include the ARM7 itself, the USB block, and the general purpose
DMA controller.
