AVME9630: VMEbus 3U Carrier

The AVME9630 is a non-intelligent slave boards that interface IP modules to the VMEbus. The half-height (3U) board holds two IP modules. All field I/O connections are made to the carrier board.

Specifications

IP Compliance (ANSI/VITA 4)

Meets IP specifications per ANSI/VITA 4-1995.
Electrical/mechanical interface: Supports single or double size IP modules. 32-bit IP modules are not supported. I/O space and ID space supported.
Memory space: Supports 1MB to 8MB per IP module.
Interrupts: Supports two interrupt requests per IP module and interrupt acknowledge cycles, D16/D08(O).

Operation

Acromag’s carrier boards provide full data access to the IP module’s I/O, ID and memory spaces. With full access to the programmable registers, you can easily configure and control the operation of the IP modules from the VMEbus.

Up to two interrupt requests are supported for each IP module. The VMEbus interrupt level is software programmable.

Individual passive filters on each IP module power supply line provide optimum filtering and power isolation between the IP modules and the carrier board.

VMEbus Compliance

Meets VME specifications per revision C.1 dated October 1985, IEC 821-1987 and IEEE 1014-1987.
Data transfer bus: A24/A16:D16/D08(EO) DTB slave; supports Read-Modify-Write cycles.
Interrupts: Creates I(1-7) programmable request levels (up to two requests sourced from each IP module). D16/D08(O) interrupter (interrupt vectors come from IP modules). Carrier registers are for control and status monitoring. Interrupt release mechanism is Release on Register Access (RORA) type.
