GENERAL INTRODUCTION
1.1 INTRODUCTION
The CompactPCI-824 is a Hot Swap Intelligent I/O Controller.
The CPCI-824 card is based on the AMCC
™ PowerPC™ 440GX, which is AMCC’s next generation
integrated processor based on the PowerPCI 440 core operating at a frequency of 667 MHz. The 440GX
supplies memory controller functions with up to 512 Mbytes of DDR SDRAM (64-bit with ECC) on an
SoDIMM module at 333 MHz DDR. The PowerPC core with 256K L2 cache, the memory controller,
the PCI-X Bridge, and the DMA controller of AMCC 440GX are among the features on the Processor
local bus operating at 128-bit and a frequency of 166 MHz. The 440GX Peripheral Bus (EPC) has three
devices; 8 Mbytes of Flash ROM, software LEDs, and external revision control registers. Additionally,
the 440GX contains four Ethernet MACs. Four Ethernet ports are provided on the CPCI-824. Two are
10/100/1Gb ports configured as RGMII and two are 10/100 Mbps ports and reconfigured as SMII. The
CPCI-824 also utilized one of the I2C bus interface units, and one of the two UART units. A block
diagram of the CPCI-824 is shown on Figure 1-1.
