Victor, NY -- Finding out what's happening on an I2C bus has always been a
challenge in the past. Was it a Send problem, a Receive problem, or what?
Now those difficulties can disappear by turning your PC-compatible
computer in to an I2C bus monitor with the ICA-90. "Clip" it on to the
bus, and you can immediately find out what's really going on. The unique
ICA-90, already popular in Europe, now comes with software to make bus
monitoring a snap. The ICA-90 is an ISA half-length card, which supports
the full 2-wire I2C (Inter-I.C.) protocol. Based on the Philips PCD8584
I2C bus controller, it requires an 8 MHz 286 or faster computer to
transparently monitor and display bus activity. Recommended by
Philips/Signetics (Europe), and currently being evaluated by Signetics
USA, the ICA-90 can also be used as a bus controller. All I2C functions
are software controllable via a library of routines supplied, including
data transmission mode and clock speed. The ICA-90 can work as an I2C
master or a slave in receiver and transmitter operations. Both polled and
interrupt-driven modes can be supported, making programming in popular
languages easy. Convenient external +5V power for devices is also
available on the 9-way D-socket which carries the I2C bidirectional Serial
Data (SDA) and Serial Clock (SCL) lines.

The ICA-90 adds inexpensive PC computing power to any I2C system and offers
an attractive alternative to using a microcontroller. ICA-90's are already
in use for setup and control of I2C systems, automatic computer monitor
setup, frequency control of radio-based telecom links, development
systems, data collection, instrumentation and chemical plant control,
production line test of I2C-based equipment, etc.

The ICA-90 includes software in C and TurboBASIC, instruction manual and
the I2C adapter card, and is available from stock at $299.
