Product details
Overview
X9317ZV8I-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 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 X9317ZV8I-2.7T1 datasheet, X9317ZV8I-2.7T1 pinout, X9317ZV8I-2.7T1 application, or X9317ZV8I-2.7T1 equivalent, key selection criteria include its 3-wire up/down interface timing (tCYC = 2µs), ratiometric temperature coefficient (±20 ppm/°C), noise performance (-120 dBV), absolute linearity (±1 MI), and industrial-grade -40°C to +85°C operation in TSSOP-8 package.
Technical Context
The X9317ZV8I-2.7T1 integrates a 7-bit up/down counter, decoder, and nonvolatile memory to control wiper position across 99 resistive elements. Its "make-before-break" switching ensures glitch-free transitions during wiper movement, with tIW (INC to RW change) ≤5µs and no wraparound behavior at tap extremes.
It operates via CS-selectable 3-wire serial interface: U/D sets direction, negative-edge-triggered INC steps position, and CS HIGH with INC HIGH initiates nonvolatile store. Power-up recalls last stored wiper position, enabling deterministic startup without host initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end Resistance | 10kΩ ±20% - defines full-scale analog range and power dissipation limit (10mW max) |
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply battery-powered and industrial 3.3V systems |
| Wiper Resistance | ≤400Ω at 2.7V - limits voltage error in high-impedance feedback paths |
| Standby Current | <5µA - enables ultra-low-power retention in always-on sensor or bias circuits |
| Resolution | 1% (100 taps) - provides 9.9mV step resolution across 1V span for fine analog adjustment |
| Absolute Linearity | ±1 MI (±1/99 of RH–RL) - ensures monotonicity and predictable transfer function in closed-loop trim |
| Ratiometric Tempco | ±20 ppm/°C - maintains stable voltage division ratio over temperature without external compensation |
Pinout & Package
Package: 8-lead TSSOP (RoHS-compliant, JEDEC MO-153 variation AC, M8.173 drawing). Dimensions: 4.40mm × 3.0mm × 1.20mm max height. Moisture Sensitivity Level (MSL): 1 (unlimited floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INC) | Increment clock input | Negative-edge-triggered control signal; toggling moves wiper one tap per edge under active CS |
| 2 (U/D) | Direction control input | Logic level selects wiper increment (HIGH) or decrement (LOW) on each INC edge |
| 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 supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper output | Movable terminal; delivers tapped voltage/current; series resistance ≤400Ω affects loading accuracy |
| 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; device responds only when LOW; HIGH with INC HIGH triggers nonvolatile store |
| 8 (VCC) | Supply voltage | 2.7V–5.5V CMOS-compatible rail; powers logic and resistor array; decoupling required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last position for ≥100 years; eliminates need for host MCU to reinitialize at power-up |
| Temperature-compensated array | ±20 ppm/°C ratiometric tempco ensures stable voltage division across -40°C to +85°C |
| Low-noise analog path | -120 dBV noise (1kHz ref) minimizes interference in sensitive audio, sensor, or reference circuits |
| Make-before-break switching | Prevents open-circuit glitches during wiper transition; critical for stable feedback loop operation |
| Ultra-low standby current | <5µA enables use in battery-backed systems where continuous bias adjustment is required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface, dual-channel, 256-tap resolution, 10kΩ, ±30% RTOTAL tolerance | Requires I²C host support; higher resolution but looser resistance tolerance affects absolute accuracy | Choose for multi-channel trim or systems with existing I²C infrastructure |
| MCP4018T-103E/OT | Single-wire (UNI/O®) interface, 64-tap, 10kΩ, ±20% RTOTAL, no nonvolatile memory | Lacks power-up recall; requires host reinitialization after reset; smaller SOT-23-6 package | Choose for space-constrained designs where volatile operation is acceptable |
Compared with AD5243BRMZ10 and MCP4018T-103E/OT, the X9317ZV8I-2.7T1 uniquely combines 3-wire simplicity, guaranteed power-up recall, and tight ratiometric tempco-making it optimal for single-channel, temperature-stable, self-initializing analog trim in industrial and optical systems.

FAQ
What is the operating temperature range for the X9317ZV8I-2.7T1?
The X9317ZV8I-2.7T1 is rated for industrial operation from -40°C to +85°C. This range is confirmed in the Ordering Information table (Page 2) and applies to all electrical specifications unless otherwise noted. The device uses temperature-compensated resistor elements to maintain ratiometric stability across this full range, making it suitable for harsh-environment applications like industrial sensors and optical modules.
Does the X9317ZV8I-2.7T1 retain its wiper position after power cycling?
Yes, the X9317ZV8I-2.7T1 stores the wiper position in nonvolatile memory and automatically recalls it upon power-up. Data retention is specified at 100 years, and endurance is rated for 100,000 store cycles. This behavior is inherent to the X9317 architecture and does not require external components or host firmware to restore settings-enabling true "set-and-forget" analog calibration.
What package type and footprint does the X9317ZV8I-2.7T1 use?
The X9317ZV8I-2.7T1 uses an 8-lead TSSOP package per JEDEC MO-153 variation AC (drawing M8.173). Its dimensions are 4.40mm × 3.0mm × 1.20mm max height, with 0.65mm lead pitch. The land pattern and soldering profile comply with Pb-free reflow standards (see TB493), and the device is RoHS-compliant with matte tin (e3) termination.
How does the 3-wire interface of the X9317ZV8I-2.7T1 differ from I²C or SPI protocols?
The X9317ZV8I-2.7T1 uses a dedicated 3-wire up/down interface (CS, U/D, INC) rather than I²C or SPI. It requires no address decoding, clock stretching, or data framing-only edge-triggered INC pulses with directional control via U/D. This simplifies firmware implementation, reduces GPIO count, and eliminates protocol overhead, making it ideal for resource-constrained MCUs or FPGA-based control logic.
Can the X9317ZV8I-2.7T1 be used in a two-terminal variable resistor configuration?
Yes, the X9317ZV8I-2.7T1 supports two-terminal operation by connecting either RH or RL to RW (wiper), effectively creating a programmable rheostat. In this mode, the device provides 100 discrete resistance values between 0Ω and 10kΩ (±20%), with wiper resistance contributing ≤400Ω at 2.7V. This configuration is commonly used for current limiting, LED brightness control, and gain-setting in discrete transistor amplifiers.
