Product details
Overview
X9317ZM8IT1 from Renesas Electronics is a digitally controlled potentiometer (XDCP™) implementing a 99-element resistor array with 100 wiper tap points, 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 variable resistor configurations in precision analog trimming applications.
For engineers reviewing the X9317ZM8IT1 datasheet, X9317ZM8IT1 pinout, X9317ZM8IT1 application, or X9317ZM8IT1 equivalent, this device is selected for DC bias adjustment, laser diode bias control, and gain/offset trim where power-up repeatability, low standby current (<5 µA), and temperature-compensated resistance stability are required.
Technical Context
The X9317ZM8IT1 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its resistor array features temperature-compensated elements with ±300 ppm/°C total resistance TC and ±20 ppm/°C ratiometric TC, ensuring stable voltage division under thermal variation.
Wiper movement uses make-before-break switching, with 1 µs typical wiper response time (tIW) and 2 µs minimum INC cycle time (tCYC). The device enters standby mode when CS is high, drawing ≤5 µA supply current, and recalls stored wiper position on power-up without external initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range for voltage divider or current-limiting use |
| Wiper Tap Points | 100 positions - enables 1% resolution for fine analog adjustment without external DAC |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation across industrial and commercial rails |
| Standby Current | <5 µA - minimizes system power budget during idle periods in battery-sensitive designs |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - eliminates need for backup power or external EEPROM |
| Wiper Resistance | 200 Ω typical at 5 V - limits loading error in high-impedance feedback paths |
| Temperature Coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - ensures predictable voltage division over -40°C to +85°C |
Pinout & Package
Package: 8-lead MSOP (RoHS-compliant, M8.118 drawing), 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, 1.10 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper up/down per U/D state |
| 2 (U/D) | Direction control input | Logic level selects wiper increment (+) or decrement (–) on each INC edge |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Return path for all internal circuitry and external analog signals |
| 5 (RW) | Wiper output | Movable terminal; provides adjustable voltage/current node with 200 Ω typical series resistance |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential or ground in voltage divider |
| 7 (CS) | Chip select | Active-low enable; HIGH initiates nonvolatile store if INC is also HIGH |
| 8 (VCC) | Power supply | 2.7–5.5 V CMOS rail; powers logic, memory, and resistor array |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and environmental sensitivity of analog pots |
| 3-wire serial up/down interface | Requires only three GPIOs-no SPI/I²C controller needed-reducing MCU resource load |
| Nonvolatile wiper position storage | Guarantees repeatable power-on state without host firmware intervention or calibration |
| Temperature-compensated resistor array | Maintains ±0.2% relative linearity over -40°C to +85°C, critical for stable sensor biasing |
| Low-power CMOS design | Enables integration into always-on subsystems with sub-µA quiescent current in standby |

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 | Single-channel, I²C interface, 10 kΩ, ±30% RTOTAL tolerance, 200 ppm/°C TC | Requires I²C master; lacks native power-up recall (needs external init) | Select when I²C bus availability and multi-device addressing outweigh need for autonomous power-on state |
| MCP4017T-103E/MS | 6-bit resolution (64 taps), 10 kΩ, ±20% RTOTAL, 500 ppm/°C TC, 5 V only | Lower resolution and higher TC reduce trimming precision in wide-temperature environments | Choose for cost-sensitive, narrow-temp-range applications where 1% step size suffices |
Compared with AD5241BRMZ10 and MCP4017T-103E/MS, the X9317ZM8IT1 offers superior long-term stability (±20 ppm/°C ratiometric TC), guaranteed power-up repeatability, and simpler 3-wire control-making it optimal for unattended, thermally demanding analog calibration tasks.

FAQ
What is the operating temperature range for the X9317ZM8IT1?
The X9317ZM8IT1 is rated for -40°C to +85°C industrial temperature operation, verified across all electrical specifications including end-to-end resistance tolerance, wiper resistance, and timing parameters. This range is confirmed in the Ordering Information table (Page 2) and Absolute Maximum Ratings section (Page 4) of the FN8183 Rev.10.01 datasheet.
Does the X9317ZM8IT1 require external components to function as a voltage divider?
No, the X9317ZM8IT1 functions as a complete 3-terminal voltage divider with RH, RW, and RL pins-no external resistors or capacitors are needed for basic operation. Its internal 99-element resistor array and wiper switching network provide full analog functionality; only VCC, VSS, and the 3-wire control lines (CS, U/D, INC) must be connected.
How is wiper position stored and recalled in the X9317ZM8IT1?
Wiper position is stored in nonvolatile memory when CS transitions HIGH while INC is held HIGH; the stored value is automatically recalled within 5 µs of VCC stabilization at power-up. This behavior is documented in the "Principles of Operation" (Page 8) and "Power-up and Down Requirements" (Page 6) sections of the datasheet, guaranteeing repeatable startup without host intervention.
Can the X9317ZM8IT1 be used with a 3.3 V supply?
Yes, the X9317ZM8IT1 supports VCC from 2.7 V to 5.5 V, making it fully compatible with 3.3 V systems. All DC and AC specifications-including ICC1 active current (≤80 µA), ISB standby current (<5 µA), and VIH/VIL logic thresholds-are validated across this full range, as specified in the Potentiometer Specifications (Page 4) and DC Electrical Specifications (Page 5) tables.
What is the maximum wiper current rating for the X9317ZM8IT1?
The X9317ZM8IT1 specifies a maximum wiper current (IW) of ±4.4 mA, measured between RH and RL terminals. This limit applies regardless of wiper position and is defined in the Potentiometer Specifications table (Page 4). Exceeding this current risks exceeding the 10 mW total power rating for 10 kΩ devices and may degrade long-term reliability.
