X9241A

• Product Introduction

X9241A, terminal voltage-3~5V，64Tap, integrated quad non-volatile digital potentiometer (DCP), Quad Digital Controlled Potentionmeters (DCP), Non-Volatile/Low Power/2-Wire/64 Taps

Terminal voltage -3~5V, 64 taps, integrated four non-volatile DCPs ◇ Product Introduction ◇ The Xicor X9241A integrates four non-volatile E2POTTM CNC potentiometers in a monolithic CMOS microcircuit. The X9241A contains four resistor arrays, each containing 63 resistor units. Between each cell and at both endpoints there are taps that can be accessed by the sliding unit. The position of the sliding unit in the array is controlled by the user via the 2-wire serial bus interface. Each resistor array is associated with a slide-end counting register (WCR) and four 8-bit data registers that can be written and read out directly by the user. The contents of the sliding end count register control the position of the sliding end in the resistor array. Data registers can be read out and written by the user. The contents of the data register can be transferred to the slide counter register to set the position of the slider. The position of the current slider can be transmitted to any of the data registers associated with it.   ◇ Product characteristics ◇ ◇ Application ◇ Four E2POTs in one package   Amplification circuit offset or gain adjustment Two-wire serial interface Parameter adjustment Terminal voltage -3.0V~5V Voltage output regulation Low-power CMOS DC bias adjustment Regarding the format of the register: write directly to the slider position; Read out the sliding end position; Each potentiometer can store up to four positions   High reliability: Persistence: 100,000 writes per register; Register data retention: 100 years   16 bytes of E2PROM memory   3 resistance array values: 2kΩ to 50kΩ mask programmable; It can be connected in series to make the resistance value from 500Ω to 200kΩ   Resolution: 64 taps per potentiometer 20-pin plastic DIP, 20-lead SOIC, and 20-lead TSSOP packages
