Product details
Overview
X9317TS8Z-REN from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 99-element resistor array with 100 wiper tap positions, nonvolatile wiper position storage, and 3-wire up/down serial interface. It operates from 2.7V to 5.5V, delivers ±20% end-to-end resistance tolerance, and supports voltage divider or two-terminal variable resistor configurations in precision analog trimming applications.
For engineers reviewing the X9317TS8Z-REN datasheet, X9317TS8Z-REN pinout, X9317TS8Z-REN application, or X9317TS8Z-REN equivalent, key selection criteria include its 100-tap resolution, 200Ω typical wiper resistance, -40°C to +85°C industrial temperature range, RoHS-compliant 8-lead SOIC package, and compatibility with LCD bias control, laser diode bias, and voltage regulator output adjustment circuits.
Technical Context
The X9317TS8Z-REN integrates a 7-bit up/down counter, decoder, nonvolatile memory for wiper position retention, and a solid-state resistor array with make-before-break switching. Its control logic responds to CS-select, U/D direction, and negative-edge-triggered INC signals to move the wiper across 100 discrete taps without wraparound.
It features ratiometric temperature coefficient of ±20 ppm/°C and absolute linearity of ±1 MI, enabling stable voltage division under thermal drift. The device enters standby mode (<5 µA ICC) when CS is high and supports store-on-CS-high-with-INC-high programming for nonvolatile updates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 100 kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Wiper Resistance | 200 Ω typical at VCC = 5V - contributes minimal offset error in precision divider configurations |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation across 3.3 V and 5 V systems |
| Standby Current | <5 µA - enables ultra-low-power retention in battery-backed or energy-sensitive designs |
| Resolution | 1% - corresponds to 1/99 step size (MI), enabling fine-grained analog tuning |
| Nonvolatile Endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable calibration systems |
| Temperature Range | -40°C to +85°C - qualified for industrial-grade embedded control and power management |
| Package | 8-lead SOIC (M8.15E) - surface-mount compatible with standard PCB assembly and reflow profiles |
Pinout & Package
Package: 8-lead narrow-body SOIC (JEDEC MS-012, M8.15E), RoHS-compliant, Pb-free matte tin termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INC | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper up/down based on U/D state |
| 2 U/D | Direction control input | Logic level determines wiper movement direction during INC transitions |
| 3 RH | High terminal | Fixed end of resistor array; functions as VCC reference in voltage divider mode |
| 4 VSS | Ground reference | Primary return path for supply and signal currents; must be low-impedance |
| 5 RW | Wiper terminal | Movable contact point; outputs intermediate voltage or adjustable resistance node |
| 6 RL | Low terminal | Fixed end of resistor array; functions as ground or VREF reference in divider mode |
| 7 CS | Chip select | Active-low enable; initiates wiper movement when low, triggers nonvolatile store when rising edge occurs with INC high |
| 8 VCC | Supply voltage | Power rail (2.7–5.5 V); powers internal logic, memory, and resistor array; requires local decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles for repeatable startup behavior |
| 3-wire serial up/down interface | Eliminates need for SPI/I²C controllers; compatible with GPIO-based microcontroller firmware |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions, critical for stable bias networks |
| Ratiometric temperature coefficient | ±20 ppm/°C ensures consistent voltage division ratio over temperature, independent of absolute RTOTAL drift |
| Low noise performance | -120 dBV (ref 1 kHz) minimizes contribution to signal path noise in sensitive analog front-ends |
| Industrial temperature qualification | -40°C to +85°C operation validated per JEDEC JESD22-A108, supporting harsh-environment deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRUZ100 | Quad-channel, I²C interface, 256-tap resolution, 100 kΩ nominal, ±30% RTOTAL tolerance | Supports multi-potentiometer synchronization and higher resolution but lacks nonvolatile storage per channel | Preferred when multiple simultaneous trim functions are required and external MCU handles persistent storage |
| MCP41010-I/P | Single-channel, SPI interface, 257-tap resolution, 10 kΩ nominal, ±20% RTOTAL, volatile wiper only | Requires external EEPROM or MCU firmware to retain settings; lower end-to-end resistance limits current-sense use | Selected for cost-sensitive, high-resolution trimming where nonvolatility is managed system-level |
Compared with AD5204BRUZ100 and MCP41010-I/P, the X9317TS8Z-REN provides guaranteed nonvolatile wiper recall without external memory or firmware overhead, simpler 3-wire control, and industrial temperature support-making it optimal for standalone, self-contained analog calibration in power supplies, displays, and optical modules.

FAQ
What is the operating voltage range for the X9317TS8Z-REN?
The X9317TS8Z-REN operates from 2.7 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. This wide supply range allows direct integration into mixed-voltage designs without level-shifting, and its specified parameters-including wiper resistance, linearity, and standby current-are validated across this full range per the FN8183 Rev 9.00 datasheet.
Does the X9317TS8Z-REN retain its wiper position after power cycling?
Yes, the X9317TS8Z-REN stores the wiper position in nonvolatile memory and automatically recalls it on power-up. This behavior is guaranteed by its EEPROM-based architecture, which provides 100-year data retention and 100,000 write cycles-ensuring reliable calibration persistence across decades of operation without external memory or firmware intervention.
What package type is used for the X9317TS8Z-REN?
The X9317TS8Z-REN uses an 8-lead narrow-body SOIC package (JEDEC MS-012, drawing M8.15E), with RoHS-compliant matte tin plating. Its 3.9 mm × 4.9 mm footprint and 1.27 mm lead pitch are compatible with standard surface-mount assembly processes and IPC-7351B land patterns.
How does the 3-wire interface of the X9317TS8Z-REN work?
The X9317TS8Z-REN uses CS (chip select), U/D (up/down), and INC (increment) signals. With CS low, each negative edge on INC moves the wiper one tap in the direction set by U/D. A rising edge on CS while INC is high stores the current position to nonvolatile memory-enabling simple GPIO-driven control without protocol overhead or clock management.
What is the maximum wiper current rating for the X9317TS8Z-REN?
The X9317TS8Z-REN supports ±4.4 mA wiper current (IW), measured between RH and RL terminals. Exceeding this limit risks degradation of wiper switch integrity or increased resistance drift. For current-sense applications, design must ensure that [V(RH) − V(RL)] / RTOTAL remains within ±4.4 mA, especially at minimum RTOTAL (80 kΩ for 100 kΩ nominal).
