System Block Diagram
The MVME2400 is a VMEbus-based single-slot Single Board Computer
based on the PowerPC MPC750 processor. The MVME2400 features two
PCI Mezzanine Card slots, an Ethernet Interface, serial port, up to 9MB of
boot FLASH, and up to 256MB of ECC protected system RAM. The Hawk
ASIC controls all of the functions previously controlled by the
Raven/Falcon chipsets, in addition to new functionality. The Hawk
provides the interface to the PowerPC 60x Bus, the interface to all on-
board SDRAMs, error notification for SDRAMs, the interface to
ROM/Flash, and the I2C master, the external status/control register
support, synchronous PPC60x/PCI clock ratio support, the interface to the
PCI, and an interrupt controller. PCI devices include: VME, Ethernet, and
Real-time clock 8KB NVRAM with RTC and battery backup (SGS-Thomson M48T559)
Peripheral Support
One 16C550-compatible async serial port routed to front panel RJ45
10BaseT/100BaseTX Ethernet interface routed to front panel RJ45
Switches Reset
(RST) and Abort (ABT)
Status LEDs Four: Board fail (BFL), CPU, PMC (one for PMC slot 2, one for slot 1)
Timers
One 16-bit timer in W83C553 ISA bridge; four 32-bit timers in MPIC
device
Watchdog timer provided in SGS-Thomson M48T59
VME I/O VMEbus P2 connector
Serial I/O One asynchronous debug port via RJ45 connector on front panel
