CPCI-824 User’s Manual
Revision 1.0, January 2006
1.2 FEATURES
•PowerPC™ Processor An AMCC 440GX embedded processor based on the AMCC
PowerPC superscalar core. It operates at a maximum frequency of
667 MHz internally.
• SDRAM Up to 512 MByte of 333 MHz DDR SDRAM is supported via a 200
pin SoDIMM module.
• Flash ROM 8 Mbytes of in-circuit sector-programmable Flash ROM provides
non-volatile storage on the CPCI-824. One 128 Kbyte sector of the
Flash ROM is reserved for the storage of non-volatile boot and
system parameters. System calls for storing parameters in this
memory are included in the Breeze Development Environmentª
• Console Serial Port An asynchronous serial port based on a 16C750 UART with an RS-
232 interface is provided for a console terminal or workstation
connection.
• Ethernet Ports Two 10/100/1Gb Base-TX Ethernet ports are provided. Each port
supports up to 1Gbps and uses a RJ45 style modular phone jack. The
MAC contained within the 440GX interfaces with 2 Broadcom
BMC5461S PHY transceivers.
Two 10/100 Base-TX Ethernet ports. Each supports up to 100 Mbps
and also uses a RJ45 style modular phone jack. In this case the MAC
contained within the 440GX interfaces with a Broadcom BCM5248.
The BCM5248 is an eight port PHY, but we are only using the first 2
ports.
• Temperature Sensors Two LM75 type programmable temperature sensors with interrupt
signaling capability are provided for system monitoring purposes.
•I
2
O Messaging The CPCI-824 supports the I
2
O specification for interprocessor
communication.
• DMA Controller The 440GX supports 4 separate DMA channels for high throughput
data transfers between PCI bus agents and the local SDRAM
memory.
• Breeze Development
Environment™
Flash-resident ROM monitor / firmware package which supports
board-level initialization and application software development.
More information on the Breeze Development Environment™ can
be found in Breeze Developer’s Manual.
• Blade Style Interface The CPCI-824 receives power, fan detect, power supply status and
geographic addressing from J1 and J2. Note that the fan detect and
power supply status signals are only available when a CPCI-824 is
installed in the system slot.
• Hot Swap The CPCI-824 is a Basic Hot Swap board, compliant with PICMG
2.1.
