DESCRIPTION
The CAT5221 is two Digitally Programmable
Potentiometers (DPPs™) integrated with control logic
and 16 bytes of NVRAM memory. Each DPP consists
of a series of 63 resistive elements connected
between two externally accessible end points. The tap
points between each resistive element are connected
to the wiper outputs with CMOS switches. A separate
6-bit control register (WCR) independently controls
the wiper tap switches for each DPP. Associated with
each wiper control register are four 6-bit non-volatile
memory data registers (DR) used for storing up to four
wiper settings. Writing to the wiper control register or
2
any of the non-volatile data registers is via a I C serial
bus. On power-up, the contents of the first data
register (DR0) for each of the four potentiometers is
automatically loaded into its respective wiper control
register (WCR).
The CAT5221 can be used as a potentiometer or as a
two terminal, variable resistor. It is intended for circuit
level or system level adjustments in a wide variety of
applications.
