card edge “finger” spacing
A-E (Carrier Field I/O).........…..50-pin Male Header with
(For APC8620)
ejector latches.
A-C (Carrier Field I/O).........…..50-pin Male Header without
(For APC8621)
ejector latches.

Power:
Board power requirements are a function of the installed IP
modules. This specification lists currents for the carrier board
only. The carrier board pr5V, +12V and -12V power
to each IP from the PCI bus. Each IP module supply line is
individually filtered and fused.
Fuses: +5 volts, 2 amp per slot
±
12 volts, 1 amp per slot
The power failure monitor circuit provides a reset to IP
modules when the 5 volt power drops below 4.27 volts
typically / 4.15 volts minimum.
Currents specified are for the carrier board only for Models
AP8620/8621, add the IP module currents for the total
current required from each supply.
+5 Volts (
±
5%)...................…...210mA, Typical
300mA, Maximum.
+12 Volts (
±
5%)...........….........0mA (Not Used)
-12 Volts (
±
5%)................….....0mA (Not Used)
PCI BUS COMPLIANCE
Specification..................................This device meets or exceeds
all written PCI Local Bus
specifications per revision 2.1
dated June 1995.
Data Transfer Bus.........................Slave with 32-bit, 16-bit, and
8-bit data transfer operation.
32-bit read or write accesses
are implemented as two 16
bit transfers to the IP modules.
PCI bus Write Cycle Time.....…....150nS Typical measured from
falling edge of FRAME# to the
falling edge of TRDY#.
PCI bus Read Cycle Time………..150nS Typical; The carrier
issues a RETRY which frees
the PCI bus while the read
request is completed. The PCI
bus will repeat the same read
request until it completes with
the requested data.
Write Complete Time……..………Time from FRAME# active
until LRDYi# active.
650nS Typical carrier register
750nS Typical 8-bit and 16-bit
IP module write (assuming 0
IP module wait states).
1250nS Typical 32-bit IP
module write (assuming 0 IP
module wait states).
Read Complete Time…….……….Time from FRAME# active
until LRDYi# active.
500nS Typical carrier register
650nS Typical 8-bit and 16-bit
IP module read (assuming 0
IP module wait states).
1100nS Typical 32-bit IP
module read (assuming 0 IP
module wait states).
Interrupts...................................….PCIbus INTA# interrupt signal
Up to two requests sourced
from each IP mapped to
INTA#. Interrupt vectors
come from IP modules via
access to IP module INT
space.
32-bit Memory Space.....................Upon power-up the system
auto- configuration process
(plug & play) maps the
carriers base address (for a
1K byte block of memory)
into the PCI bus 32-bit
Memory Space.
INDUSTRIAL I/O PACK COMPLIANCE
Specification.............................….This device meets or exceeds
all written Industrial I/O Pack
specifications per ANSI/VITA 4
1995 for 8MHz operation, only.
Supports Type I and Type II ID
space formats.
Electrical/Mechanical Interface.....Carrier supports five single-
(For APC8620) size IP modules (A-E), or two
double-size and one single
size IP module. 32-bit IP
modules are not supported.
Electrical/Mechanical Interface.....Carrier supports three single-
(For APC8621) size IP modules (A-C), or one
double-size and one single
size IP module. 32-bit IP
modules are not supported.
I/O Space..................................…16-bit and 8-bit:
Supports 128 byte values per
IP module.
ID Space...................................…16 and 8-bit; Supports Type 1
32 bytes per IP (consecutive
odd byte addresses). Also
supports Type II 32 words per
IP via D16 data transfers.
Memory Space.........................….Not Supported.
Interrupts.................................…..Supports two interrupt requests
per IP and interrupt
acknowledge cycles via
access to IP INT space.
