1.3.4 Supported Memory
The cPCI-6765(A) supports two 144-pin SO-DIMM sockets and hence can
accommodate up to a maximum total memory size of 512MB. The memory
type must be 3.3V SDRAM and can come in size of 32MB, 64MB, 128MB or
256MB. The entire memory array may be configured as either standard
(un-buffered) SDRAM or buffered SDRAM and the DIMM sockets can be
populated in any order. ADLINK factory provides pre-mounting memory for
OEM project. Please contact ADLINK sales representatives for available
memory configurations.
1.3.5 Interrupts
Two enhanced interrupt controllers provide the cPCI-6765(A) with a total of
15 interrupt inputs. Interrupt controller features include support for:
• Level-triggered and edge-triggered inputs
• Individual input masking
• Fixed and rotating priorities
Interrupt sources include:
• Counter/Timers
• Serial I/O
• Keyboard
• Printer Port
• Floppy disk
• IDE interface
• Real-Time Clock
• On-board PCI devices
Enhanced capabilities include the ability to configure each interrupt level for
active high going edge or active low-level inputs. The cPCI-6765(A)'s
interrupt controllers reside in the Intel 82371EB (PIIX4E)
