GENERAL INTRODUCTION
1.1INTRODUCTION
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.
