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, add the IP
module currents for the total current required from each supply.
+5 Volts (
±
5%)...................…...... 180mA, Typical
250mA, Maximum.
+12 Volts (
±
5%)...........…............ 0mA (Not Used)
-12 Volts (
±
5%)............................ 0mA (Not Used)
CompactPCI BUS COMPLIANCE
Specification................................ This device meets or exceeds
all written PCI Specification
Version 2.1 & CompactPCI
Specification PICMG 2.0 R2.1.
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.
CompactPCI bus Write
Cycle Time................................... 150nS typical measured from
falling edge of FRAME# to the
falling edge of TRDY#.
CompactPCI bus Read
Cycle Time................................... 150nS typical; The carrier issues
a RETRY which frees the
CompactPCI bus while the read
request is completed. The
CompactPCI bus will repeat the
same read request until it
completes with the requested data.
ACPC8625 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).
ACPC8625 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.............................…..... CompactPCIbus 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 carrier’s 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)
and IP I/O Mapping to
CompactPCI (PICMG 2.4 R1.0).
Electrical/Mechanical Interface....Carrier supports four single-size
IP modules (A-D), or two double-
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..................................... A16/D08(O); supports 32 bytes
per IP (consecutive odd-byte
addresses) ID Data Format I. D16
is also supported with pull-ups on
the carrier board holding the upper
8-bits high.
Memory Space............................. Not Supported.
Interrupts..................................… Supports two interrupt requests
per IP and interrupt acknowledge
cycles via access to IP INT space.
Access LED
(Illuminate duration).................... 0.125 second, typical
ENVIRONMENTAL
Operating Temperature................0 to +70
°
C;
-40 to +85
°
C (E Versions)
Note that visual LED performance
may be degraded below -20
o
C.
Relative Humidity......................... 5-95% non-condensing
Storage Temperature................... -55 to +100
°
C.
Non-Isolated.................................CompactPCI bus and IP module
logic commons have a direct
electrical connection. As such,
unless the IP module provides
isolation between the logic and
field side, the field I/O connections
are not isolated from the
CompactPCI bus.
Radiated Field Immunity (RFI)..... Designed to comply with
IEC1000-4-3 Level 3 (10V/m at
frequencies 27MHz to 500MHz)
and European Norm EN50082-1.
Electromagnetic Interference
Immunity (EMI)............................ No digital upset under the
influence of EMI from switching
solenoids, commutator motors,
and drill motors.
Electrostatic Discharge
Immunity (ESD)........................... Complies with IEC1000-4-2
Level 1 (2KV direct contact
discharge) at field input/output
terminals and European Norm
EN50082-1.
Electric Fast Transient
Immunity EFT.............................. Complies with IEC1000-4-4
Level 2 (0.5KV at field input and
output terminals) and European
Norm EN50082-1.
