Product details
Overview
X9317ZS8-2.7T1 from Renesas Electronics is a low-noise, low-power, 100-tap digitally controlled potentiometer (XDCP™) with nonvolatile wiper position storage, 2.7V–5.5V supply range, 10kΩ end-to-end resistance, and MSOP-8 package. It functions as a solid-state three-terminal voltage divider or two-terminal variable resistor for precision analog trimming in embedded bias control circuits.
For engineers reviewing the X9317ZS8-2.7T1 datasheet, X9317ZS8-2.7T1 pinout, X9317ZS8-2.7T1 application, or X9317ZS8-2.7T1 equivalent, this device supports stable DC bias adjustment, laser diode current control, and voltage regulator output tuning without external EEPROM or host MCU state management.
Technical Context
The X9317ZS8-2.7T1 implements a 99-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 7-bit up/down counter is controlled via CS, U/D, and edge-triggered INC signals, and stores wiper position in nonvolatile memory on CS↑/INC↑.
It features temperature-compensated resistance (±300 ppm/°C total TC, ±20 ppm/°C ratiometric), 1% absolute linearity (±1 MI), and low 200Ω typical wiper resistance at 5V - all specified across –40°C to +85°C industrial temperature range.
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 interface with 3.3V and 5V logic systems without level shifters |
| Wiper Tap Resolution | 100 positions (0–99) - provides 1% step resolution for fine analog calibration |
| Standby Current | <5µA - minimizes quiescent power in battery-powered or always-on bias circuits |
| Nonvolatile Storage | 100-year data retention, 100,000 write cycles - eliminates need for external memory or boot-time initialization |
| Linearity Error | ±1 MI absolute, ±0.2 MI relative - ensures predictable voltage division across full wiper travel |
| Wiper Resistance | 200Ω typ. (5V), 400Ω typ. (2.7V) - limits signal path degradation in high-impedance feedback networks |
| Thermal Coefficient | ±300 ppm/°C total, ±20 ppm/°C ratiometric - maintains stable gain/offset over temperature in precision analog stages |
Pinout & Package
Package: 8-lead MSOP (M8.118), RoHS-compliant, moisture sensitivity level (MSL) 3, 145°C/W junction-to-ambient thermal resistance.
| 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 supply and signal currents; must be low-impedance for noise immunity |
| 5 (RW) | Wiper output | Movable terminal; delivers interpolated voltage/current between RH and RL; 200Ω typical series resistance |
| 6 (RL) | Low terminal | Fixed end of resistor array; connects to lower potential (e.g., ground or negative rail) |
| 7 (CS) | Chip select | Active-low enable; wiper updates only when CS = LOW; HIGH with INC = HIGH triggers nonvolatile store |
| 8 (VCC) | Power supply | 2.7V–5.5V CMOS-compatible supply; powers internal logic, memory, and resistor array |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last-set position across power cycles - enables repeatable startup behavior without host MCU intervention |
| 3-wire serial interface | CS/U/D/INC requires no clock or data lines - simplifies PCB routing and reduces GPIO count vs. SPI/I²C DCPs |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio over –40°C to +85°C |
| Make-before-break switching | Prevents open-circuit glitches during wiper movement - critical for stable operation in feedback loops |
| Low 2.7V operation | Full functionality down to 2.7V - supports modern low-voltage microcontrollers and portable systems |
| RoHS-compliant MSOP-8 | Compact 3mm × 3mm footprint with exposed pad option - suitable for space-constrained analog front-ends |

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, 10kΩ, SOIC-8; higher resolution but no nonvolatile store by default | Requires external EEPROM or MCU firmware to retain settings across power cycles | Choose when I²C bus integration is preferred and host MCU can manage memory persistence |
| MCP41010-I/P | SPI interface, 256-tap, 10kΩ, PDIP-8; volatile wiper register only, no built-in NV memory | Needs continuous MCU polling or periodic refresh to maintain position; unsuitable for unattended power-up behavior | Choose for cost-sensitive prototyping where external memory or active control is acceptable |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9317ZS8-2.7T1 delivers autonomous power-cycle recovery, simpler 3-wire control, and guaranteed 100-year data retention - making it optimal for maintenance-free analog calibration in industrial and telecom infrastructure.

FAQ
What is the operating temperature range for the X9317ZS8-2.7T1?
The X9317ZS8-2.7T1 is rated for –40°C to +85°C industrial temperature operation. This range is fully supported for all electrical specifications including end-to-end resistance tolerance, linearity, and nonvolatile memory endurance. The device uses temperature-compensated resistor elements to maintain ratiometric stability across this span.
Does the X9317ZS8-2.7T1 require an external power-on reset circuit?
No, the X9317ZS8-2.7T1 does not require an external power-on reset. Upon power-up, it automatically recalls the last stored wiper position from nonvolatile memory within 5µs. The recommended power sequence is to assert VCC/VSS first, then apply control signals - no external timing or reset logic is needed for reliable initialization.
How is nonvolatile storage triggered on the X9317ZS8-2.7T1?
Nonvolatile storage on the X9317ZS8-2.7T1 is triggered by a rising edge on CS while INC is held HIGH. This single-event command writes the current wiper position to memory in 5–10ms. No additional clock cycles, address bytes, or confirmation reads are required - the operation is self-contained and deterministic.
Can the X9317ZS8-2.7T1 be used in a two-terminal variable resistor configuration?
Yes, the X9317ZS8-2.7T1 supports two-terminal operation by connecting either RH or RL to RW and using the remaining terminal with the wiper. In this mode, it functions as a digitally adjustable current-limiting or gain-setting resistor with 100-step resolution and 10kΩ maximum value - commonly used in laser diode bias and op-amp feedback networks.
What is the maximum wiper current rating for the X9317ZS8-2.7T1 at 2.7V supply?
At VCC = 2.7V, the X9317ZS8-2.7T1 specifies a maximum wiper current (IW) of ±4.4mA. Wiper resistance rises to 400Ω typical (1000Ω max) under these conditions, limiting power dissipation to safe levels. Exceeding ±4.4mA risks exceeding the 10mW total power rating and may degrade long-term reliability.
