New 12-Bit Data Acquisition Systems Communicate with
Microprocessors Over 4 Wires вЂ“ Design Note 22
As board space and semiconductor package pins become
more valuable, serial data transfer methods between
microprocessors (MPUs) and their peripherals become
more and more attractive. Not only does this save lines
in the transmission medium, but, because of the savings
in the package pins, more function can be packed into
both the MPU and the peripheral. Users are increasingly
able to take advantage of these savings as more MPU
manufacturers develop serial ports for their products (1-3).
However, peripherals which are able to communicate with
these MPUs must be available in order for users to take full
advantage. Also, MPU serial formats are not standardized
so not all peripherals can talk to all MPUs.
The LTCВ®1290 Family
A new family of 12-bit data acquisition circuits has been
developed to communicate over just 4 wires to the recently
developed MPU synchronous serial formats as well as
to MPUs which do not have serial ports. These circuits
feature software configurable analog circuitry including analog multiplexers, sample and holds, bipolar and
unipolar conversion modes and the ability to shut power
completely off. They also have serial ports which can be …
