Product details
Overview
X9317ZV8 from Renesas Electronics 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 functions as a three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in low-power systems operating from 2.7V to 5.5V.
For engineers reviewing the X9317ZV8 datasheet, X9317ZV8 pinout, X9317ZV8 application, or X9317ZV8 equivalent, key selection criteria include end-to-end resistance tolerance (±20%), wiper resistance (200–400 Ω at 5V), standby current (<5 µA), ratiometric temperature coefficient (±20 ppm/°C), and TSSOP-8 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The X9317ZV8 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its "make-before-break" switching ensures continuity during wiper transitions, while the resistor array exhibits temperature-compensated behavior with ±300 ppm/°C total resistance TC and ±20 ppm/°C ratiometric TC.
Control is executed via CS (chip select), U/D (direction), and edge-triggered INC inputs. A HIGH-to-LOW transition on INC moves the wiper; CS HIGH with INC HIGH initiates nonvolatile store. Power-up recalls the last stored position, enabling deterministic startup behavior without host initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10 kΩ ±20% - defines full-scale analog range and load interaction in voltage divider or current-setting configurations |
| Wiper Resistance | 200–400 Ω at VCC = 5V - directly impacts signal path insertion loss and minimum achievable output impedance |
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation across legacy 3.3V and modern mixed-voltage systems |
| Standby Current | <5 µA - enables battery-powered or energy-sensitive applications with minimal quiescent drain |
| Nonvolatile Endurance | 100,000 data changes per bit - guarantees long-term field reliability for recalibration or adaptive tuning cycles |
| Ratiometric Tempco | ±20 ppm/°C - ensures stable voltage division ratio over temperature, critical for bias and reference circuits |
| Resolution | 1% (1/99 step) - provides fine-grained analog adjustment without requiring external DAC or microcontroller interpolation |
| Output Noise | –120 dBV (ref. 1 kHz) - supports low-noise signal conditioning in sensor front-ends and audio bias paths |
Pinout & Package
Package: 8-lead TSSOP (JEDEC MO-153, variation AC), RoHS-compliant, body dimensions 4.40 mm × 3.0 mm × 1.20 mm max, lead pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control line; toggling moves wiper up/down per U/D state; determines timing of wiper position change (tIW ≤ 5 µs) |
| 2 (U/D) | Direction control input | Logic level sets wiper movement direction during INC transitions; may be changed dynamically while CS is LOW |
| 3 (RH) | High terminal | Fixed end of resistor array; connected to highest potential in voltage divider mode; not necessarily at VCC potential |
| 4 (VSS) | Ground reference | Primary return path for supply and signal currents; must be low-impedance to maintain linearity and noise performance |
| 5 (RW) | Wiper output | Movable terminal delivering intermediate voltage/current; series resistance (200–400 Ω) affects loading and bandwidth |
| 6 (RL) | Low terminal | Fixed end of resistor array; connected to lowest potential in voltage divider mode; not necessarily at VSS potential |
| 7 (CS) | Chip select | Active-low enable; device responds only when CS is LOW; HIGH with INC HIGH triggers nonvolatile store and enters standby |
| 8 (VCC) | Power supply | 2.7–5.5V CMOS supply; powers logic and switch circuitry; ICC1 ≤ 80 µA active, ISB ≤ 5 µA standby |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper position storage | Retains last-set tap position across power cycles; eliminates need for host MCU reinitialization or calibration on boot |
| 3-wire serial up/down interface | Requires only three GPIOs (CS, U/D, INC); no clock or data lines needed - simplifies integration into resource-constrained MCUs |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric tempco ensures stable voltage division ratio over –40°C to +85°C industrial range |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions; avoids glitches in feedback loops or bias networks |
| Low-power CMOS design | Standby current <5 µA and active current ≤80 µA enable use in always-on sensor nodes and portable equipment |
| 100-tap resolution with 1% step size | Provides sufficient granularity for precision gain/offset trim without requiring external scaling resistors or DACs |

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, ±30% RTOTAL tolerance, higher ICC (120 µA active) | Requires I²C bus and pull-up resistors; better resolution but looser resistance tolerance affects absolute accuracy | Choose AD5170BRMZ-10 when I²C infrastructure exists and finer resolution outweighs tighter tempco requirements. |
| MCP41HV51-103 | SPI interface, 257-tap resolution, 10 kΩ, ±20% RTOTAL, 10V tolerant, higher wiper resistance (1200 Ω) | Supports higher voltage rails (up to 10V), but higher wiper R degrades low-voltage signal integrity and increases thermal noise | Choose MCP41HV51-103 for high-voltage biasing where 10V operation is required and wiper R impact is acceptable. |
Compared with AD5170BRMZ-10 and MCP41HV51-103, the X9317ZV8 offers superior ratiometric stability (±20 ppm/°C vs. ±100 ppm/°C typical), lower standby current (<5 µA vs. >10 µA), and simpler 3-wire control-making it optimal for low-power, precision analog trimming where deterministic startup and minimal GPIO usage are critical.

FAQ
What is the operating temperature range for the X9317ZV8?
The X9317ZV8 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", including X9317ZV8. The device maintains specified performance-including ±20 ppm/°C ratiometric temperature coefficient and <5 µA standby current-across this full range.
Does the X9317ZV8 require external programming hardware to store wiper position?
No. The X9317ZV8 stores wiper position in on-chip nonvolatile memory using only its native 3-wire interface: assert CS LOW to select, toggle INC with U/D set to desired direction to reach target tap, then raise CS HIGH while holding INC HIGH. This initiates an internal 5–10 ms store cycle-no external programmer, voltage pump, or special command sequence is needed. The X9317ZV8 retains the value for 100 years.
What is the maximum wiper current rating for the X9317ZV8?
The X9317ZV8 supports a maximum wiper current (IW) of ±4.4 mA, as specified in the Absolute Maximum Ratings and DC Electrical Specifications tables (pages 4–5). This limit applies regardless of VCC (2.7–5.5V) and ensures safe operation of the internal CMOS switches and resistor array under continuous DC load conditions.
Can the X9317ZV8 be used in a single-supply inverting amplifier configuration?
Yes. The X9317ZV8 is explicitly validated for single-supply inverting amplifier topologies, as shown in Figure 7 of the datasheet (page 9). In this configuration, it serves as the feedback resistor (Rf), enabling programmable gain adjustment. Its 10 kΩ end-to-end resistance, low wiper resistance, and make-before-break switching prevent transient errors during gain changes.
Is the X9317ZV8 pin-compatible with other members of the X9317 family?
Yes. All X9317 variants-including X9317ZV8 (TSSOP-8), X9317WS8Z (SOIC-8), and X9317WM8Z (MSOP-8)-share identical 8-pin pinouts and electrical behavior per the Pin Configurations and Pin Descriptions (pages 3–4). The only differences are package type, marking, and temperature grade; PCB layout can be reused across variants with appropriate land pattern adjustments.
