intersil X9428 Low Noise/Low Power/2-Wire Bus handbook
The X9428 is a single‑digitally controlled potentiometer (XDCP) that integrates a 10 kΩ resistor array, four non‑volatile data registers and a 6‑bit volatile wiper counter register. It operates over a 2‑wire serial interface (SCL/SDA) and supports up to eight devices on the bus.
Key features include low standby current (< 1 pA), high endurance (100 k data changes per bit), 100‑year data retention, and selectable supply voltages from 2.7 V to 5.5 V (including negative V‑). The device is offered in 16‑lead DIP, 16‑lead SOIC and 14‑lead TSSOP packages and is rated for commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges.
