MVME2432-3 Motorola VME Processor Module original new brand
MVME2432-3 Motorola VME Processor Module original new brand
The MVME2432-3 is a family of single-slot VME processor modules.
It consists of the MPC750 processor and L2 cache that directly connects to
the MPC750, the Hawk ASIC, which is made up of the PCI Bridge (PHB),
the Multi-Processor Interrupt Controller (MPIC), and the System Memory
Controller (SMC). The MVME2400 series also includes 9MB of Flash
memory, 32MB to 256MB of ECC-protected SDRAM, and a rich set of
features of I/O peripherals.

The I/O peripheral devices on the PCI bus include the Universe II VMEbus interface ASIC and two PMC slots. Functions provided by the ISA bus are: one asynchronous serial port, a real-time clock, counters/timers, and a software-readable header.
The MVME2432-3 series board interfaces to the VMEbus via the P1 and P2 connectors, which adopt the 5-row 160-pin connectors specified in the proposed VME64 Extension Standard. It also draws +5V, +12V, and -12V power from the VMEbus backplane through these two connectors. Additional 2.0V and 3.3V power is regulated onboard from the +5V power supply.
Front panel connectors on the MVME2432-3 series board include: an RJ45 connector for the Ethernet 10Base-T/100Base-TX interface, and an RJ45 connector for the async serial debug port. The front panel also features reset and abort switches and status LEDs.
The MVME2432-3 series is equipped with two IEEE1386.1 PCI Mezzanine Card (PMC) slots. These PMC slots support 64-bit operation and both front and rear I/O. Pins 1 through 64 of PMC slot 1 connector J14 are routed to row C and row A of the 5-row DIN P2 connector. Pins 1 through 46 of PMC slot 2 connector J24 are routed to row D and row Z of P2.
Additional PCI expansion is supported via a 114-pin Mictor connector. This connection enables stacking of one or two PMCspan dual-PMC carrier boards to enhance I/O capability. Each PMCspan board requires an additional VME slot.
