ICS's VXI-5501 and VXI-5502 Proto-
type Kits are flexible, low-cost solutions for
developing prototype or short-run VXIbus
modules. Both kits use ICS's VXI-5524 Reg-
ister-based Interface card to interface with
the VXIbus. The VXI-5524 provides the
user with a simple but powerful interface
for controlling his circuits from the VXI-
bus. Theusercircuitsareconstructedonthe
supplied bare or prototyping board that
mates with the VXI-5524 to form a complete
'C' size, VXI module as shown below.
A choice of VXI hardware shield kits
lets the user assemble one, two or three-slot
wide modules which accommodate stan-
dard or oversize components or even wire-
wraptails. Applicationsarefabricatingpro-
totype VXIbus modules, packaging circuits
in VXIbus modules and building short-run
modules.
Each hardware kit includes the side
shields, front panel, and all hardware to
finish the module. The VXI-5501 Kit in-
cludes a bare copper-clad board for mount-
ing RF devices. The VXI-5502 Kit includes
a prototyping board
with holes on 0.1 inch
centers for mounting
socketsor components.
VXI Interface
ICS's VXI-5524 VXI Interface Card is a
VXI register-based interface that meets the
latest VXI-1 and VXI-2 Specifications for an
Extended Register Based Device. The VXI-
5524 Interface Card provides all of the VXI
required registers and makes all of the de-
vice register addresses available to the user's
circuits in a way that is the easiest for the user
to use. The user can alter the default values
in the VXI-5524's registers to personalize the
finished VXI module as his product. The
user's setting can be saved and recalled at
power turn-on.
The VXI-5524 provides the user with a
48 line parallel digital interface for control-
ling or reading signals, a 16-bit wide data
expansion bus for driving additional cir-
cuits, an interrupt input and two VXIbus
Trigger lines. In some applications, the VXI-
5524's registers provide all of the needed
signals so that the user does not have to
construct additional decoding or driver cir-
cuits. The user's interface also includes all
seven VXIbus power lines, a selectable clock
and ground.
DESCRIPTION

MODULE KITS
-5502
The VXI-5502 is
shown on the right
with the shields re-
moved to show how
theprototypingboard
is mates to the VXI-
5524 Register-based
VXI Interface.

User Interface
Figure 1 shows a Block Diagram of
the VXI-5524 and the User's Interface.
The VXI-5524 provides the user with 48
Digital I/O lines, a Data Expansion Bus,
a VXIbus interrupt and TTL Trigger
lines. The 48 Digital I/O lines are con-
figurable as inputs or outputs in 16 line
groups by setting bits in the VXI-5524's
ConfigurationRegister. Asoutputs,each
line can sink 40 mA or source 20 mA to
drive most any TTL/CMOS compatible
device. Whenconfigured as inputs,each
line is a high impedance TTL gate with
a 33 Kohm pullup to 5 Vdc for sensing
open collector lines, contact closures or
TTL/CMOS level signals.
The Data Expansion Bus is a 16 bit
wide bus that extends the unused VXI
register addresses and data lines to the
user's circuits. Examples in the manual
show how to decode the address lines
and connect registers, FIFOs and other
circuits to the Data Expansion Bus.
The VXI-5524 extends a selected
pair of TTL Trigger lines to the user's
interface. The TrigIn# line can be used
to initiate an action such as data capture,
data conversion, etc. in the user's cir-
cuits. The TrigOut# line can be used to
pulse a VXIbus TTL Trigger line and
initiate action in another module.
TheVXI-5524hasan IRQ input that
latches three Cause code lines when
pulsed. The Cause lines are new with
the VXI-2 Specification and gives a reg-
ister-based device a way of communi-
cating the cause of the interrupt when it
is queried by the Slot 0 Controller. VX-
Ibus IRQ line selection and interrupt
enable is controlled by bits set in the
new Interrupt Control Register.
The VXI-5524 passes all seven VX-
Ibus voltages and a 10 MHz clock on to
the user's interface. The user can select
either the VXI-5524's internal 10 MHz
oscillator or the VXIbus ECL 10 MHz
clock as the clock source.
VXI-5524 Register Map
Figure 2 shows the VXI-5524's reg-
ister map. Each VXIbus module is as-
signed 32 (16-bit) register addresses in
the VXI A16 address space. The register
addresses values in Figure 2 are offsets
from the module's logical address. i.e.
The Device Type Register is 0x02 HEX
which is the module's logical address
plus 2.

Figure 2 VXI-5524 Register Map
The lower 16 register addresses
are used for the VXIbus interface, the
upper 16 register address are for the
device. The VXI-5524 uses the top three
register addresses for the Digital I/O
lines. Register addresses 0x20 through
0x38 are made available to the user's
circuits with the Data Expansion Bus.
The Configuration and Interrupt
Control registers configure the Digital
I/O lines and control the Trigger and
Interrupt operation. The ID, Type,
Serial Number and Version registers
identifytheVXImoduleanditscapabil-
ity. The user can change these registers
to configure the interface and personal-
ize the finished module as his product .
All register values are then saved in an
EEPROM on the VXI-5524 and are auto-
maticallyrecalled atpowerturn-on time
or when the board is reset.
