Product details
Overview
X9317WV8Z-2.7 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 tolerance of ±20%, wiper resistance ≤400Ω at 2.7V, and standby current <5µA. It serves as a three-terminal voltage divider or two-terminal variable resistor in precision analog trim applications.
For engineers reviewing the X9317WV8Z-2.7 datasheet, X9317WV8Z-2.7 pinout, X9317WV8Z-2.7 application, or X9317WV8Z-2.7 equivalent, key selection considerations include its TSSOP-8 package, 10kΩ end-to-end resistance, 3-wire up/down interface timing (tCYC = 2µs), nonvolatile store capability on CS↑/INC↑, and operation across 0°C to +70°C.
Technical Context
The X9317WV8Z-2.7 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 100 discrete taps. Its resistor array uses 99 matched elements with ratiometric temperature coefficient of ±20 ppm/°C and absolute linearity of ±1 MI.
Control logic responds to negative-edge-triggered INC input while CS is low, with U/D determining direction. Wiper position is stored to EEPROM when CS transitions high with INC high, enabling power-up recall without external configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog range for voltage division or current limiting |
| Supply Voltage Range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level shifting |
| Wiper Resistance | ≤400Ω at 2.7V - limits insertion error and signal attenuation in precision divider configurations |
| Standby Current | <5µA - supports ultra-low-power operation in battery-backed or energy-constrained systems |
| Nonvolatile Endurance | 100,000 data changes per bit - ensures long-term reliability for field-adjustable calibration routines |
| Resolution | 1% (100 taps) - provides fine-grained analog adjustment granularity for gain/offset trimming |
| Temperature Coefficient | ±300 ppm/°C (absolute), ±20 ppm/°C (ratiometric) - maintains stable resistance ratio over temperature |
| Interface Timing | tCYC = 2µs - supports fast digital trimming cycles without MCU firmware bottlenecks |
Pinout & Package
Package: 8-lead TSSOP (JEDEC MO-153, variation AC), 4.4mm × 3.0mm body, 0.65mm pitch, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper one tap in U/D direction |
| 2 (U/D) | Direction control input | Logic level sets wiper movement direction (high = up, low = down) during INC transitions |
| 3 (RH) | High terminal | Fixed end of resistor array; connects to higher potential in voltage divider configurations |
| 4 (VSS) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper terminal | Movable contact point; output node for adjustable voltage or variable resistance paths |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential (e.g., ground) in voltage divider use |
| 7 (CS) | Chip select | Active-low enable; device responds only when CS is low; rising edge with INC high stores wiper |
| 8 (VCC) | Supply voltage | Power input for internal logic and resistor array; supports 2.7V–5.5V operation with low ICC1 ≤80µA |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last programmed tap position across power cycles; eliminates startup recalibration |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - no clock or data lines needed for basic trimming |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio across 0°C to +70°C |
| Make-before-break switching | Prevents open-circuit transients during wiper movement; avoids signal glitches in sensitive analog paths |
| Low-power CMOS design | Standby current <5µA and active ICC1 ≤80µA enable integration into always-on sensor front-ends |
| Robust reliability | 100-year data retention and 100,000 write cycles support field-programmable calibration in industrial equipment |

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, 10kΩ, 2.7V–5.5V, MSOP-10 | Requires I²C master; higher resolution but larger footprint and different pinout | Choose when I²C bus availability and finer 0.39% step resolution outweigh TSSOP-8 size constraints. |
| MCP41010-I/P | SPI interface, 256-tap resolution, 10kΩ, 2.3V–5.5V, PDIP-8 | Needs SPI clock/data lines; through-hole package unsuitable for space-constrained PCBs | Prefer when legacy through-hole assembly or SPI infrastructure already exists and board area is not constrained. |

FAQ
What is the operating temperature range for the X9317WV8Z-2.7?
The X9317WV8Z-2.7 is rated for 0°C to +70°C (commercial temperature range). This is confirmed in the Ordering Information table on page 2 of FN8183 Rev.10.01, where X9317WV8Z-2.7 is explicitly listed with "0 to +70" under Temperature Range. It uses the same TSSOP-8 package (M8.173) and electrical specifications as other commercial-grade X9317 variants.
Does the X9317WV8Z-2.7 support true 3.3V operation?
Yes, the X9317WV8Z-2.7 fully supports 3.3V operation. Its VCC specification is 2.7V to 5.5V (page 4, Potentiometer Specifications), and all DC/AC parameters-including ICC1 ≤80µA, ISB <5µA, and tCYC = 2µs-are guaranteed across this range. The "-2.7" suffix denotes extended low-voltage capability, distinguishing it from standard 4.5V–5.5V variants like X9317WV8Z.
How is wiper position stored and recalled in the X9317WV8Z-2.7?
Wiper position is stored in nonvolatile memory when CS transitions high while INC is held high-a dedicated store command. Upon power-up, the X9317WV8Z-2.7 automatically recalls the last stored value and configures the wiper accordingly, as described in the Power-up and Down Requirements section (page 6) and Principles of Operation (page 8). No external initialization is required.
What is the maximum wiper current rating for the X9317WV8Z-2.7 at 2.7V supply?
At VCC = 2.7V, the maximum wiper current (IW) is ±4.4mA, per the Absolute Maximum Ratings table (page 4). The wiper resistance is specified as ≤1000Ω under this condition, meaning the device can sustain up to ~4.4mA through RW without exceeding safe operating limits-critical for current-sensing or LED bias applications.
Can the X9317WV8Z-2.7 be used in a two-terminal variable resistor configuration?
Yes, the X9317WV8Z-2.7 supports two-terminal operation by connecting either RH or RL to RW externally, effectively using the device as a programmable rheostat. The datasheet explicitly states this capability on page 1 ("used as a two-terminal variable resistor for current control") and illustrates it in Figure 4 (page 9), confirming suitability for current-setting applications like laser diode bias.
