PCI93 Datasheet
3-Volt Compatible I2C Communications PCI Adapter PCs
The PCI93LV is able to work with I C-Bus systems running on supplies between 2 and 6V so is ideally
suited for use in low-power 3V applications. The PCI93LV is a PCI-based version of Calibre's well2
proven ICA90 I C-Bus Communications Adapter which is now widely regarded as the industry standard
tool and is currently in use by hundreds of companies large and small.
The package supplied includes the PCI card, a comprehensive user manual, Windows 95/98/2000/NT4
and XP device drivers to enable users to integrate the product with their own software applications and
a real-time I C-Bus monitor program.
Ready-to-run WINI2C software for immediate control and development of I C-Bus systems is also
available as an optional extra.
True I C Compatibility
I C-Bus voltage between 2 and 6V (user alterable)
True 30/70% logic thresholds track with supply voltage
Operates as Master, Slave or Real-Time Monitor
Fits any PC with free PCI slot
Win95/98/2000/NT4 & XP device drivers and monitor software included
I C Configuration through software
I C Connection via 9 way D socket
+2 to 6V power available on I C connector
The PCI93LV is based around the Philips PCF854 I C Bus controller to support the full I C
communications protocol and plugs into any available PCI slot in your PC. Bus termination and
protection are all link selectable while I C configuration and all other protocol functions are software
controllable. The I C-Bus voltage is selectable by a trim-pot accessible through the card mounting
All I C features are available under software control including data transmission mode (master/slave,
transmitter/receiver), own slave address and SCL clock speed when operating as a master
(1.5/11/45/90kHz). A "transparent" real-time bus monitor program is also provided. The PCI93LV fully
supports multi-master operation and associated bus arbitration.
Make Your PC I2C Compatible
The PCI93LV adapter adds inexpensive PC computing
power to any I2C system and presents an attractive
alternative option to the use of a microprocessor or
microcontroller. Current applications include development
systems, production line test and set-up of I2C based
equipment, control of systems and specialised data links
between equipment.
there are so many different types and sources available it
would be impossible to provide specific code to suit all
applications. The software routines provided allow any I 2C
device, current or future, to be communicated with. It
should be noted that all I2C-Bus operations are on a bytewise basis.
On the disc provided with the PCI93LV/C there is a ready
to run real-time bus monitor program which traces all
transmissions on an externally mastered I2C bus and
records them in an ASCII file on disc. The monitor traces
in real-time without affecting the I2C system it is monitoring
- to do so the card must be used in a PC which is not
running other tasks at that time (such as FindFast,
Outlook) otherwise data may be missed. The monitor does
not provide a real-time display to the screen, all data is
stored on disc. It does carefully post-process the data
recorded into easily understood information.
Win95/98/2000/NT4 & XP device drivers and a real-time
bus monitor program are included with the PCI93LV/C
package. Win95/98/2000/NT4 & XP ready to run software
applications are available as optional extras. Note: the
PCI93LV/C cannot be used under DOS or Win3.1
Standard software is in the form of function libraries for use
in users' own application software.
The principle of the software is to provide all the I 2C
functions - I2C adapter set-up (including card's own I2C
slave address and SCL clock speed), Start & slave
address transmission, byte transmission, byte reception,
Stop transmission and of course access to status
The user then builds these high-level
functions into the necessary program for driving their
particular I C devices. This option was chosen as opposed
to providing drivers for specific I2C devices since
Calibre UK Ltd undertakes I2C-Bus software development
and support contracts to customers' own requirements.
Calibre also offers a large range of LCD displays and
interfaces, colour monitors, computer video distribution
amplifiers, scan converters and other display related
products. Please call for further information.
