Description
The CPC710 IBM PCI Bridge and Memory
Controller is a highly integrated host bridge device
that interfaces PowerPC 60x buses to SDRAM-
based system memory and also provides two PCI
interfaces. It supports up to four processors with
pipelining for up to six outstanding transaction
requests.
supports a standard 32-bit, 33MHz PCI bus, while
the other supports 64 bits at up to 66MHz for
graphics and high speed communications.
An internal DMA controller allows high speed data
transfer between Memory and I/O. Store-gathering
enhances the CPU-to-I/O performance.
The memory controller supports SDRAM, allowing
the memory to burst data on most bus cycles at
100MHz or 133MHz.
Technology: IBM CMOS SA-12E, 0.25 µm
Package: 35mm, 728-ball flip chip-plastic ball grid
array (FC-PBGA)
For system designs requiring high I/O bandwidth,
there are two PCI host bus bridges. One bridge
Power (estimated): Typical 2.1W, Maximum 2.6W
