Product details
Overview
X9315WSIZ from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 3-wire serial interface (CS/U/D/INC). It operates at 5V ±10%, delivers ±20% end-to-end resistance tolerance, and supports industrial temperature range (–40°C to +85°C) in Pb-free SOIC-8 package. It functions as a three-terminal voltage divider or two-terminal variable resistor in analog signal trimming applications.
For engineers reviewing the X9315WSIZ datasheet, X9315WSIZ pinout, X9315WSIZ application, or X9315WSIZ equivalent, this page provides verified technical context, confirmed pin roles, real-world use scenarios in precision analog circuits, and validated alternative options for industrial-grade digital potentiometer selection.
Technical Context
The X9315WSIZ uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic 31-resistor ladder. Wiper movement follows make-before-break switching, preventing open-circuit transients during tap transitions. The device stores wiper position in nonvolatile EEPROM upon CS↑ with INC HIGH, enabling automatic recall at power-up.
It features low-power CMOS operation: active current ≤80 µA (increment), ≤400 µA (store), and standby current ≤5 µA. Terminal voltage range is 0 to VCC, wiper resistance is 200 Ω (typ.) at VCC = 5V, and absolute linearity error is ±1 MI (minimum increment = RTOTAL/31).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5241BRMZ10 | I²C interface, 1024-tap resolution, 10 kΩ RTOTAL, 2.7–5.5 V supply | Higher resolution but requires I²C bus resources; lacks native nonvolatile store-on-power-down behavior | Choose when higher resolution and I²C ecosystem integration outweigh simpler 3-wire control and guaranteed power-up restore. |
| MCP41010-I/P | SPITM interface, 257-tap resolution, 10 kΩ RTOTAL, 2.7–5.5 V supply, volatile wiper register | No nonvolatile memory; requires external MCU to reload wiper position after power-up | Choose when SPI interface is already used in system and wiper state management is handled centrally by firmware. |
Compared with AD5241BRMZ10 and MCP41010-I/P, the X9315WSIZ offers deterministic power-up behavior without host intervention, minimal GPIO usage (3 wires), and proven industrial temperature reliability-making it optimal for standalone analog trimming where firmware dependency must be eliminated.

FAQ
What is the maximum wiper current rating for the X9315WSIZ?
The X9315WSIZ specifies a maximum wiper current (IW) of ±3.75 mA under recommended operating conditions. This limit ensures safe operation within the 10 mW maximum power rating and prevents degradation of the internal resistor array or wiper switches. Exceeding this current may cause irreversible resistance drift or open-circuit failure. The wiper resistance is 200 Ω (typ.) at 5V, consistent with this rating.
Does the X9315WSIZ retain its wiper position after power cycling?
Yes, the X9315WSIZ automatically recalls the last stored wiper position from nonvolatile memory upon power-up. This occurs without host intervention because the device performs a recall operation during power stabilization. The stored value remains intact for up to 100 years, and endurance is rated at 100,000 data changes per bit-ensuring long-term reliability in field-deployed X9315WSIZ units.
Can the X9315WSIZ operate from a 3.3V supply?
No, the X9315WSIZ is specified only for 5V ±10% (4.5 V to 5.5 V) operation. It is not rated for 3.3V supply use. For 2.7–5.5 V operation, Intersil offers the X9315WSIZ-2.7 variant (distinct part number), which shares the same SOIC-8 package and industrial temperature range but uses different internal voltage references and logic thresholds. Using X9315WSIZ at 3.3V violates Absolute Maximum Ratings and risks functional failure.
What is the meaning of "X9315WSIZ" suffix letters?
In X9315WSIZ: "W" denotes 10 kΩ RTOTAL; "S" indicates SOIC-8 package; "I" specifies –40°C to +85°C industrial temperature grade; "Z" signifies Pb-free (RoHS-compliant) finish. The full ordering code X9315WSIZT1 adds tape-and-reel packaging (T1), per Intersil's TB347 reel specification. These suffixes are defined in the official FN8179 Rev.2.00 Ordering Information table.
How does the X9315WSIZ handle wiper movement during rapid INC toggling?
When INC is toggled rapidly with CS LOW, the X9315WSIZ advances the wiper one position per negative edge, regardless of U/D state. During multi-step movement, make-before-break switching connects multiple taps briefly, temporarily reducing effective RTOTAL. The tIW (INC to VW change) delay is 1–5 µs, and minimum INC cycle time (tCYC) is 4 µs-so sustained rates above 250 kHz may cause missed steps or metastability. For reliable operation, maintain tCYC ≥ 4 µs and tIH/tIL ≥ 1 µs.
