Renesas X9313WPIZ

Overview

X9313WPIZ from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 3-wire serial interface (CS/U/D/INC), nonvolatile wiper position storage, and 10kΩ end-to-end resistance. It operates from 4.5V to 5.5V, supports ±VCC terminal voltages, and is housed in an 8-lead PDIP package. Used for precision analog trimming in industrial sensor calibration and programmable gain control circuits.

For engineers reviewing the X9313WPIZ datasheet, X9313WPIZ pinout, X9313WPIZ application, or X9313WPIZ equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases, and confirmed alternative parts - all specific to the X9313WPIZ variant with -40°C to +85°C temperature range and Pb-free PDIP packaging.

Technical Context

The X9313WPIZ implements a 31-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 5-bit up/down counter drives a decoder that selects one of 32 wiper positions, with nonvolatile memory storing the last position for automatic recall at power-up.

Control logic responds to CS (active-low chip select), U/D (direction), and edge-triggered INC inputs. A store operation occurs only when CS rises while INC is high; otherwise, wiper adjustments remain volatile. Terminal voltage tolerance spans –VCC to +VCC, supporting bipolar signal conditioning.

Equivalent & Alternatives

The following parts are listed as comparable options for similar digitally controlled potentiometer applications.

Compared with X9313WPIZ, AD5243BRMZ10 offers higher resolution and dual-channel capability but lacks guaranteed ±V_CC terminal voltage support and requires I²C infrastructure; MCP41010-I/P matches the 10kΩ value and supply range but trades nonvolatility for SPI compatibility-making X9313WPIZ optimal for robust, self-contained analog trimming in harsh environments.

FAQ

What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313WPIZ?

The absolute maximum voltage difference (ΔV = |VH − VL|) for X9313WPIZ is 10V, as specified in the Absolute Maximum Ratings table. This limit applies regardless of V_CC level and ensures safe operation of the internal resistor array and switches. Exceeding 10V risks permanent damage to the device, even if individual terminal voltages remain within –V_CC to +V_CC.

Does X9313WPIZ retain its wiper position after power cycling?

Yes, X9313WPIZ stores the wiper position in nonvolatile memory and automatically recalls it upon power-up. This behavior is guaranteed by its 100-year data retention specification and requires no external components or host intervention. The stored value persists across all power cycles unless explicitly overwritten via a store command (CS rising edge with INC = HIGH).

Can X9313WPIZ be used with bipolar analog signals such as ±5V?

Yes, X9313WPIZ supports terminal voltages from –V_CC to +V_CC. With V_CC = 5V, RH/VH and RL/VL can each swing from –5V to +5V, enabling direct use in bipolar op-amp circuits, AC-coupled signal paths, and differential sensor interfaces without level-shifting circuitry.

What is the wiper resistance of X9313WPIZ and how does it affect circuit performance?

X9313WPIZ has a typical wiper resistance (R_W) of 40Ω at V_CC = 5V, with a maximum of 100Ω. This series resistance introduces minimal error in high-impedance voltage divider configurations (<0.1% error for R_TOTAL = 10kΩ), but becomes significant in low-impedance current-sensing or feedback paths-requiring layout-aware placement and verification against target accuracy.

Is X9313WPIZ compatible with modern lead-free reflow processes?

No, X9313WPIZ is supplied in a Pb-free PDIP package (MDP0031) intended exclusively for through-hole wave soldering. Its plastic body and leadframe are not qualified for reflow soldering due to thermal stress limitations. Attempting reflow may cause delamination or internal damage; wave solder profile must follow IPC-J-STD-020 guidelines for through-hole Pb-free assembly.
