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

any of the non-volatile data registers is via a I C serial

bus. On power-up, the contents of the first data

automatically loaded into its respective wiper control

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.
