CAT5401 Quad Digital Potentiometer (POT) with 64 Taps and SPI Interface Description The CAT5401 is four digital POTs integrated with control logic and 16 bytes of NVRAM memory. Each digital POT 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 digital.

CAT5401 Quad Digitally Programmable Potentiometers (DPP™) with 64 Taps and SPI Interface FEATURES s Four linear-taper digitally programmable H GEN FR ALO EE LE A D F R E ETM s Automatic recall of saved wiper settings at potentiometers s 64 resistor taps per potentiometer s End to end resistance 2.5kΩ, 10kΩ, 50kΩ or 100kΩ s Potentiometer control and memory access via power up s 2.5 to 6.0 volt operation s Standby current less than 1µA s 1,000,000 nonvolatile WRITE cycles s 100 year nonvolatile memory data retention s 24-lead SOIC, 24-lead TSSOP and BGA s Industrial temperature range SPI interface: Mode (0, 0) and (1, 1) s Low wiper resistance, typically 80Ω s Nonvolatile memory storage for up to four wiper settings for each potentiometer DESCRIPTION The CAT5401 is four 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 SPI serial bus. On power-up, the contents of the first data .
