1 / 17 page 1 DESCRIPTION The CAT5409 is four Digitally Programmable Potentiometers (DPP™) integrated with control logic and 16 bytes of NVRAM memory. A separate 6-bit control register (WCR) independently controls the wiper tap position 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 2-wire serial bus (I2C-like). On power-up, the CAT5409 Quad Digitally Programmable Potentiometers (DPP™) with 64 Taps and 2-wire Interface FEATURES s Four linear-taper digital potentiometers s 64 resistor taps per potentiometer s End-to-end resistance 2.5k Ω, 10kΩ, 50kΩ or 100kΩ s 2-wire interface (I2C like) s Low wiper resistance, typically 80 Ω Ω Ω Ω Ω s Four non-volatile wiper settings for each potentiometer s Recall of saved wiper settings at power-up s 2.5 to 6.0 volt operation s Standby current less than 1 µA s 1,000,000 nonvolatile WRITE cycles s 100 year nonvolatile memory data retention s 24-lead SOIC, 24-lead TSSOP and BGA s Write protection for data register PIN CONFIGURATION FUNCTIONAL DIAGRAM © 2004 by Catalyst Semiconductor, Inc. Characteristics subject to change without notice Document No. 2010, Rev. I contents of the first data register (DR0) for each of the four potentiometers is automatically loaded into its respective wiper control register (WCR). The Write Protection ( WP) pin protects against inadvertent programming of the data register. The CAT5409 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.
