ESD VME-PMC-CPU/2-CC-32P2 I/O Controller - VMEbus base board for two 32P2 single PMC modules, P2-pin assignment acc. to IEEE Std 1386-2001, Table 8 (interconnection between 16 pins of the PMC-modules). Conduction Cooled, extended temperature range: -40...+85ºC. Simple Type: I/O Controller

The VMEbus unit VME-PMC-CPU/2 is a VME64-base board that can carry up to two PMC modules of normal size. For the VMEbus connection, the VME-PCI bridge Tsi148 by Tundra is used. The Tsi148 allows the board to operate either as slave or as master on the VMEbus. If the board operates as master, it supports a 4-level arbiter. Any of the seven-interrupt request lines accepts application of the VMEbus interrupt, and the board connects to the VMEbus by two 160-pin VG-connectors (complementary to DIN41612) for VME64 systems. LEDs in the front panel indicate an active VMEbus-interrupt request and a VMEbus access onto the board. A high efficient PowerPC MPC8349 powers the board at 533 or 667 MHz with the advantage of frugal power consumption. The fast floating-point unit of type 603 allows complex algorithms at formidable speed. The memory enables ECC with a capacity of 512 Mbyte or optional 1 Gbyte DDR2-typed RAM. The flash memory of 2 Gbyte allows even complex and ambitious operating systems as well as user's application. The on-board FPGA controls the set-up of the board resources, including the complex Tsi148 VME interface and the PMC slots, but is mighty enough to enable a programming API for the programmers usage. The board also includes 1 Gbit Ethernet port and 2 RS-232 serial ports with access through PO rear I/O pins. Designed according to the IEEE STD 1386-2001 standard (except the standard I/O pin routing), both PMC slots allow insertion of all PMC modules, that use 3.3 V signaling only. In addition to the connectors for the PMC address/ data and control signals, every slot of the VME-PMC-CPU/2-CC has an I/O connector that applies the I/O-signals of the PMC modules to VMEbus connector P2. Two different P2 pin assignments are available: In the standard configuration, each P2-pin connects to one I/O pin of the PMC-modules acc. to VITA 35 (P4V2-64ac, P4V0-64). In the option ‘-32P’, the pin assignment is acc. to IEEE Std 1386-2001, Table 8. This pin assignment offers the connection of the two PMC-modules via P2, because several PMC-I/O-signals are shorted at P2.
