Product details
Overview
X9317TPI-2.7 from Renesas Electronics is a low-noise, low-power, 100-tap digitally controlled potentiometer (XDCP™) with nonvolatile wiper position storage, 10 kΩ end-to-end resistance, and 2.7 V to 5.5 V supply operation. It implements a 99-element resistor array with make-before-break wiper switching and is used for precision DC bias adjustment in analog signal chains.
For engineers reviewing the X9317TPI-2.7 datasheet, X9317TPI-2.7 pinout, X9317TPI-2.7 application, or X9317TPI-2.7 equivalent, key selection criteria include its 2.7 V minimum supply voltage, ±20% RTOTAL tolerance, 100-year data retention, 100,000-cycle endurance, and compatibility with three-wire up/down serial control in space-constrained industrial and consumer trim circuits.
Technical Context
The X9317TPI-2.7 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps on a temperature-compensated 99-resistor array. Its solid-state architecture eliminates mechanical wear and enables repeatable, stable resistance ratios.
Wiper movement is edge-triggered via INC input under CS enable, with direction set by U/D logic level. The device supports both three-terminal voltage divider and two-terminal variable resistor configurations, and automatically recalls stored wiper position at power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale resistance range and sets current-handling limits in voltage divider or current-sense applications |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct interface with 3.3 V and 5 V systems without level-shifting |
| Wiper Current Rating | ±4.4 mA - determines maximum allowable current through RW terminal without performance degradation |
| Standby Current | <5 µA - supports ultra-low-power operation during system sleep or idle states |
| Resolution | 1% (100 taps) - provides 99 discrete resistance steps between RH and RL terminals |
| Nonvolatile Endurance | 100,000 write cycles - ensures long-term reliability for field-adjustable calibration routines |
| Data Retention | 100 years - guarantees wiper position persistence across product lifetime without battery backup |
Pinout & Package
Package: 8-lead TSSOP (RoHS-compliant, JEDEC MO-153 AC, M8.173 drawing), 4.4 mm × 3.0 mm body, 0.65 mm pitch, 1.20 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control line; toggling moves wiper one tap in direction set by U/D |
| 2 (U/D) | Direction control input | Logic level selects wiper increment (+) or decrement (–) on each INC edge |
| 3 (RH) | High-side terminal | Fixed end of resistor array; connects to higher potential in voltage divider configuration |
| 4 (VSS) | Ground reference | Return path for supply and signal currents; must be low-impedance for noise-sensitive trim |
| 5 (RW) | Wiper output | Movable terminal; delivers intermediate voltage/current based on selected tap position |
| 6 (RL) | Low-side terminal | Fixed end of resistor array; connects to lower potential or ground in voltage divider |
| 7 (CS) | Chip select | Active-low enable; initiates wiper movement when LOW and triggers nonvolatile store when rising edge occurs with INC HIGH |
| 8 (VCC) | Power supply | 2.7 V to 5.5 V input; powers internal logic, memory, and resistor array; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last programmed tap position across power cycles, enabling consistent startup behavior without host reinitialization |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions, avoiding glitches in sensitive analog feedback paths |
| Temperature-compensated resistor array | ±300 ppm/°C total resistance drift ensures stable gain/offset trim over -40°C to +85°C industrial range |
| Low-noise operation | -120 dBV (re: 1 Vrms @ 1 kHz) supports high-fidelity audio and precision sensor signal conditioning |
| Three-wire serial interface | Eliminates need for SPI/I²C peripherals; compatible with GPIO-controlled microcontrollers and FPGA logic |

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 RTOTAL, 2.7 V to 5.5 V supply, but no nonvolatile storage | Requires continuous host communication to retain settings; unsuitable for unpowered calibration persistence | Select when I²C bus availability and higher resolution outweigh need for power-loss immunity |
| MCP41010-I/P | 3-wire SPI interface, 256-tap resolution, 10 kΩ RTOTAL, 2.7 V to 5.5 V supply, volatile wiper register only | No built-in EEPROM; wiper resets to mid-scale on power-up unless externally managed | Choose for SPI-native systems where host firmware handles initialization and recalibration |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317TPI-2.7 uniquely combines 3-wire up/down simplicity, guaranteed power-up recall, and industrial-grade reliability-making it optimal for maintenance-free analog trimming where host intervention is impractical or undesirable.

FAQ
What is the operating temperature range for the X9317TPI-2.7?
The X9317TPI-2.7 is rated for industrial operation from –40°C to +85°C. This range is confirmed in the Ordering Information table (Page 2) under the "TEMPERATURE RANGE (°C)" column for part numbers ending in "-2.7" and "IZ", and is supported by absolute maximum ratings and parameter testing conditions throughout the datasheet.
Does the X9317TPI-2.7 require external pull-up resistors on its control pins?
No, the X9317TPI-2.7 does not require external pull-up resistors. Input leakage current is specified at ±10 µA (Page 5), and VIH/VIL thresholds are defined relative to VCC (e.g., VIH ≥ 0.7 × VCC). The device relies on clean, actively driven GPIO signals from the host controller-not passive biasing-for reliable INC, U/D, and CS timing.
How is nonvolatile storage triggered on the X9317TPI-2.7?
Nonvolatile storage is triggered by a rising edge on the CS pin while the INC pin is held HIGH. This sequence writes the current wiper position to EEPROM. The operation takes 5–10 ms (tWR, Page 6), after which the device enters standby mode. No additional commands or address cycles are needed-storage is implicit and atomic.
Can the X9317TPI-2.7 be used in a two-terminal variable resistor configuration?
Yes, the X9317TPI-2.7 supports two-terminal operation by connecting either RH or RL to RW (as shown in Figure 4, Page 9). In this mode, it functions as a digitally adjustable rheostat with resistance ranging from near-zero (wiper at terminal) to RTOTAL (wiper at opposite end), maintaining the same 100-tap resolution and nonvolatile recall capability.
What is the maximum wiper current rating for the X9317TPI-2.7 at 2.7 V supply?
At VCC = 2.7 V, the maximum wiper current (IW) is ±4.4 mA, as specified in the Potentiometer Specifications table (Page 4). This limit applies regardless of wiper position and ensures safe operation within the device's power dissipation budget and switch integrity constraints.
