Product details
Overview
X9317ZM8-2.7T1 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) with 100 wiper tap points, nonvolatile wiper position storage, and 2.7V to 5.5V supply operation. It implements a 99-element resistor array with temperature-compensated end-to-end resistance (±20% tolerance), low standby current (<5 µA), and 200 Ω typical wiper resistance - used for precision DC bias adjustment in LCD driver circuits.
For engineers reviewing the X9317ZM8-2.7T1 datasheet, X9317ZM8-2.7T1 pinout, X9317ZM8-2.7T1 application, or X9317ZM8-2.7T1 equivalent, this device supports three-terminal voltage divider and two-terminal variable resistor configurations, requires no external programming interface beyond its 3-wire up/down control (CS/U/D/INC), and delivers ratiometric temperature stability (±20 ppm/°C) critical for analog trim in industrial sensor signal chains.
Technical Context
The X9317ZM8-2.7T1 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps on a monolithic 99-resistor array. Its "make-before-break" switching ensures continuity during wiper transitions, while the 3-wire serial interface enables deterministic tap stepping without clock or data framing overhead.
Wiper position is stored on CS↑ with INC high, recalled automatically at power-up, and retained for 100 years. The device operates as either a three-terminal potentiometer (RH–RW–RL) or two-terminal variable resistor (RW–RL or RW–RH), with RH/RL terminals rated for 0 V to VCC and wiper current limited to ±4.4 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range for voltage division or current limiting in trim applications. |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V logic systems without level-shifting. |
| Wiper Resistance | 200 Ω typical (at 5 V), 400 Ω typical (at 2.7 V) - contributes minimal series error in precision feedback paths. |
| Standby Current | <5 µA - allows integration into battery-powered or ultra-low-power systems without significant quiescent drain. |
| Resolution | 1% (100-tap) - provides 9.9 mV step resolution across 1 V span, sufficient for fine gain/offset calibration. |
| Relative Linearity | ±0.2 MI - ensures consistent step-size accuracy across the entire resistive array for monotonic response. |
| Ratiometric Tempco | ±20 ppm/°C - guarantees stable voltage division ratio over temperature, critical for sensor biasing. |
| Nonvolatile Endurance | 100,000 write cycles - supports field recalibration and lifetime parameter tuning without wear-out risk. |
Pinout & Package
Package: 8-lead MSOP (RoHS-compliant, JEDEC MO-187-AA compliant, package drawing M8.118, body size 3.0 mm × 3.0 mm × 0.85 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control line; toggling moves wiper one tap up/down depending on U/D state. |
| 2 (U/D) | Direction control input | Logic level selects wiper movement direction: HIGH = increment, LOW = decrement. |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to highest potential node in voltage divider configuration. |
| 4 (VSS) | Ground reference | Primary return path for all internal circuitry and external load currents. |
| 5 (RW) | Wiper output | Movable terminal; provides analog output proportional to tap position; 200 Ω typical series resistance. |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lowest potential node (e.g., ground or negative rail). |
| 7 (CS) | Chip select | Active-low enable; wiper updates only when CS is LOW; rising edge with INC HIGH triggers nonvolatile store. |
| 8 (VCC) | Supply voltage | Power input for logic and analog sections; supports 2.7 V to 5.5 V operation with <5 µA standby draw. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental sensitivity inherent in electro-mechanical pots. |
| Nonvolatile wiper position storage | Recalls last-set tap position at every power-on, enabling repeatable startup conditions without host initialization. |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric tempco ensures stable voltage division ratio across -40°C to +85°C operating range. |
| 3-wire up/down serial interface | Requires only three GPIOs (CS/U/D/INC); no clock generation, address decoding, or firmware stack needed. |
| Low-power CMOS design | Draws <5 µA in standby and <80 µA active - suitable for always-on sensor front-ends and portable instrumentation. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions, avoiding glitches in feedback loops and amplifier inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 256-tap resolution, 10 kΩ nominal, 500 ppm/°C tempco, higher ICC (120 µA active) | Requires I²C master and pull-up resistors; less suitable for space-constrained layouts due to larger SOIC-10 footprint | Preferred when system already uses I²C bus and higher resolution is required for fine-grained trimming |
| MCP41010-I/P | SPIM interface, 256-tap, 10 kΩ, 100 ppm/°C tempco, 1 µA standby, but volatile memory only | Needs host MCU to reinitialize wiper at each power-up; unsuitable for unattended recalibration or fail-safe startup | Appropriate for cost-sensitive consumer designs where power-on repeatability is not required |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317ZM8-2.7T1 uniquely combines nonvolatile storage, ultra-low standby current (<5 µA), and a minimal 3-wire interface - making it optimal for battery-backed industrial sensors and displays requiring guaranteed power-on repeatability without host intervention.

FAQ
What is the operating temperature range for the X9317ZM8-2.7T1?
The X9317ZM8-2.7T1 is rated for industrial operation from -40°C to +85°C. This range is confirmed in the Ordering Information table (page 2) for part numbers ending in "IZ", and applies to the X9317ZM8-2.7T1 variant. All electrical specifications - including wiper resistance, linearity, and tempco - are guaranteed across this full range.
Does the X9317ZM8-2.7T1 retain its wiper position after power cycling?
Yes, the X9317ZM8-2.7T1 stores wiper position in nonvolatile memory and automatically recalls it upon power-up. This behavior is intrinsic to the device architecture: the stored value is loaded into the wiper counter at power-on reset, ensuring repeatable startup without host MCU involvement. Data retention is specified at 100 years.
What package type does the X9317ZM8-2.7T1 use?
The X9317ZM8-2.7T1 uses an 8-lead MSOP package (package drawing M8.118), measuring 3.0 mm × 3.0 mm × 0.85 mm. This is explicitly stated in the Ordering Information table (page 2) under "PACKAGE DESCRIPTION" for the "X9317WM8Z-2.7T1" and "X9317WM8IZ-2.7T1" entries, which share the same base part number and package designation.
Can the X9317ZM8-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9317ZM8-2.7T1 can be configured as a two-terminal variable resistor by connecting either RH or RL to RW externally and using the remaining terminal plus RW as the adjustable element. This is explicitly supported in the Applications section (page 1) and Figure 4 ("Two Terminal Variable Resistor; Variable Current"), and enables current-setting functions like laser diode bias control.
What is the maximum wiper current rating for the X9317ZM8-2.7T1?
The X9317ZM8-2.7T1 has a maximum wiper current rating of ±4.4 mA, as specified in the Potentiometer Specifications table (page 4) under "IW Wiper Current". This limit applies across the full operating temperature range and must not be exceeded to avoid degradation of wiper resistance or long-term reliability.
