Serial Ports: Two 16550-compatible serial ports are featured onthe WMIVME-7750 front panel. The serial
channel has a 16-byteFlFO to support baud rates up to 115 kbaud. Requires twomicro-DB-9 to
A y-adapter cable isincluded.
Flash Memory: The VMlVME-7750 provides up to 1 Gbyte of lDECompactFlash memory accessible
through the secondary lDEport. The VMlVME-7750 Bl0S includes an option to allow theboard to boot from the Flash memory.
Timers: The VMlVME-7750 provides the user with two 16-bittimers and two 32-bit timers (in addition
to system timers].These timers are mapped in l/O space, and are completelysoftware programmable.
VMIVME-7750-740000
Watchdog Timer: The VMlvME-7750 provides a software-programmable watchdog timer. The watchdog timer is
enabledunder software control. Once the watchdog timer is enabled,software must access the timer within the
specified timer periodor a timeout will occur. A user jumper allows the timeout tocause a reset. independent of the
jumper, software can enablethe watchdog timeout to cause a nonmaskable interrupt (NMl]or a VMEbus SYSFAIL.
Nonvolatile SRAM: The VMIVME-7750 provides 32 Kbyte ofnonvolatile SRAM. The contents of the SRAM are
preserved when+5V power is interrupted or removed from the unit.
PMC Expansion Site: The VMlVME-7750 suppOrtS IEEE P1386common mezzanine card specification with a
5V PCl mezzaninecard (PMCl expansion site.The PMc site provides for standardl/O out the VMEbus
front panel, An optional l/O connection tothe VMEbus P2 connection can be provided.
