FEATURES
•
MPC8240 Processor
The microprocessor is Motorola’s integrated MPC8240 PowerPC.
The device integrates a Motorola 32-bit superscalar PowerPC 603e
core, running at 250 MHz internally, and a Peripheral Components
Interconnect (PCI). The core boasts a 16 Kbyte instruction cache, a
16 Kbyte data cache and floating-point support. Memory can be
accessed through the memory controller to the core processor or
from the PCI bus.
•
21154 PCI-to-PCI Bridge
The 21154 has a 64-bit primary bus interface and a 64-bit
secondary interface. The 21154 primary bus interfaces with the 64-
bit CompactPCI bus and the secondary bus interfaces with the 32-
bit PCI bus on the MPC8240. This allows the CPCI-810 to
function as a system controller in a CompactPCI system.
•
SDRAM
64 MBytes of SDRAM expandable to 192 MBytes via a 144 pin
SoDIMM running at 100MHz.
•
PMC Module
The CPCI-810 has one location for a 32-bit PMC Module. The
module can contain I/O interfaces to customize the CPCI-810 for
different applications. The PMC Module resides on the PCI bus of
the MPC8240 and can be accessed by the MPC8240 or a host on
the
CompactPCI
bus. Devices on the PMC Module can DMA
data into local memory or through the bridge to host memory.
•
CompactPCI
Interface
The CPCI-810 meets the PICMG Rev. 1.0 Specification for system
slot adapters. The PCI bus runs at 33MHz.
•
Flash ROM
2 Mbytes of in-circuit sector-programmable Flash ROM.
•
Ethernet Ports
Two 10/100BaseTx ethernet ports are provided. Each port supports
up to 100Mbps a uses a RJ45 style module phone jack
•
Console Serial Port
An RS-232 serial port is provided for a console terminal or
workstation connection. The serial port supports up to 115 Kbps
and uses a phone jack to DB25 cable supplied with the CPCI-810
board.
•
LM75
Two LM75s are provided for temperature monitoring.
•
Fan Monitoring
Fan monitoring is provided for two separate fan frequency inputs.
•
Timers
Four 31-bit timers are available to generate interrupts.
•
DMA Controller
The MPC8240 supports 2 separate DMA channels for high
throughput data transfers between PCI bus agents and the local
SDRAM memory.
•
