Product details
Overview
X9313ZSZ-3 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 32-tap linear resistor array with nonvolatile wiper position storage, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage range, and 1kΩ end-to-end resistance - used for precision analog trimming in voltage divider and variable resistor configurations.
For engineers reviewing the X9313ZSZ-3 datasheet, X9313ZSZ-3 pinout, X9313ZSZ-3 application, or X9313ZSZ-3 equivalent, key selection considerations include its 3V–5.5V supply compatibility, -40°C to +85°C industrial temperature grade, SOIC-8 package, 100,000-cycle endurance, and 100-year data retention - critical for maintenance-free calibration in embedded control systems.
Technical Context
The X9313ZSZ-3 integrates a 31-element resistor ladder, 5-bit up/down counter, nonvolatile memory, and make-before-break wiper switching. Its wiper position is set via edge-triggered INC input under CS enable, with direction controlled by U/D logic level.
Wiper position is stored on CS↑ while INC = HIGH, enabling power-up recall of last setting. Terminal voltages support ±VCC operation (±3V to ±5.5V), and wiper resistance is 40Ω typical at VCC = 5V - enabling direct connection to op-amp inputs or feedback nodes without buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 1kΩ ±20% - defines full-scale adjustment range and current-handling capability in voltage divider or rheostat mode. |
| Supply voltage range | 3V to 5.5V - supports dual-rail operation across legacy 3.3V and 5V systems without level-shifting. |
| Wiper tap count | 32 positions (0–31) - provides 3.125% resolution per step for fine-grained analog tuning. |
| Nonvolatile storage endurance | 100,000 write cycles - enables field calibration updates over product lifetime without wear-out concerns. |
| Power-up behavior | Recalls last stored wiper position - ensures deterministic startup state without host MCU initialization sequence. |
| Terminal voltage range | −VCC to +VCC - allows bidirectional signal handling (e.g., ±2.5V rails) without external clamping diodes. |
| Standby current | 500µA max - minimizes quiescent power in battery-backed or low-power sleep modes. |
Pinout & Package
Package: 8-lead SOIC (Pb-free, RoHS compliant), JEDEC MS-012-AA compliant, body size 4.9mm × 3.9mm × 1.75mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply rail | Accepts 3V–5.5V; powers internal logic, memory, and resistor array; must be stable before CS activation. |
| VSS | Ground reference | Common return for all digital and analog functions; requires low-impedance connection to minimize noise coupling. |
| CS | Chip select input | Active-low enable; stores wiper position on rising edge when INC = HIGH; places device in standby when high and INC low. |
| U/D | Direction control | Logic level sets wiper movement direction (HIGH = increment, LOW = decrement) during subsequent INC transitions. |
| INC | Increment clock input | Negative-edge triggered; advances wiper one tap per valid edge; timing requires tIL ≥ 1µs and tIH ≥ 1µs. |
| RH/VH | High terminal | Fixed end of resistor array; voltage rating −VCC to +VCC; connects to upper rail in voltage divider applications. |
| RL/VL | Low terminal | Fixed end of resistor array; voltage rating −VCC to +VCC; connects to lower rail or ground in voltage divider applications. |
| RW/VW | Wiper terminal | Movable tap output; series resistance 40Ω typical at 5V; directly interfaces with op-amp inputs or feedback networks. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, vibration sensitivity, and contact noise - ideal for sealed or high-reliability enclosures. |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - reduces MCU GPIO usage and eliminates need for SPI/I²C peripherals or address decoding. |
| Nonvolatile wiper position storage | Retains setting for 100 years; enables factory calibration, user presets, or adaptive compensation without backup power or EEPROM writes. |
| Temperature-compensated resistor array | ±300 ppm/°C RTOTAL drift - maintains trim accuracy across industrial temperature range without software correction. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - avoids glitches in feedback loops or bias networks. |
| ±VCC terminal voltage tolerance | Supports bipolar signal paths (e.g., ±2.5V) without external level shifters - simplifies design in audio, sensor, and instrumentation circuits. |

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 RTOTAL, 2.7–5.5V supply | Requires I²C bus and address configuration; higher resolution but larger step size due to 10kΩ value | Preferred when dual independent pots or finer resolution needed; not drop-in due to different interface and pinout |
| MCP41010-I/P | SPI interface, single-channel, 256-tap, 10kΩ RTOTAL, 2.7–5.5V supply, volatile wiper register | No nonvolatile storage - wiper resets to mid-scale on power-up; requires host MCU to reload setting | Selected for cost-sensitive designs where calibration is performed at boot; unsuitable for unattended or battery-powered retainment use cases |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313ZSZ-3 offers unique advantages in 3-wire simplicity, guaranteed power-up recall, and ±VCC analog voltage tolerance - making it optimal for robust, low-pin-count analog trimming where deterministic startup and bipolar signal handling are required.

FAQ
What is the maximum allowable voltage across RH and RL terminals for X9313ZSZ-3?
The X9313ZSZ-3 specifies ΔV = |VH − VL| ≤ 4V for the Z-grade variant. This limit ensures safe operation of the internal resistor array and wiper switches. Exceeding 4V may cause irreversible damage or accelerated wear, even if individual terminal voltages remain within −VCC to +VCC bounds. Always verify voltage differential in your circuit layout before finalizing.
Does X9313ZSZ-3 require an external pull-up or pull-down resistor on the INC pin?
No, the X9313ZSZ-3 does not require external biasing on the INC pin. Its input leakage current is ±10µA over temperature, and VIH/VIL thresholds are defined relative to VCC and VSS. A clean, actively driven digital signal meeting tIL ≥ 1µs and tIH ≥ 1µs timing is sufficient. Adding pull resistors may distort edge timing and violate AC specifications.
Can X9313ZSZ-3 be used in a bipolar ±5V system where VH = +5V and VL = −5V?
Yes, X9313ZSZ-3 supports terminal voltages from −VCC to +VCC. With VCC = 5V, VH and VL may each swing from −5V to +5V, enabling direct use in ±5V op-amp circuits. However, the absolute voltage difference |VH − VL| must not exceed 4V - so this configuration is only valid if VH and VL differ by ≤4V (e.g., VH = +2V, VL = −2V).
How is wiper position stored in nonvolatile memory on X9313ZSZ-3?
Wiper position is stored when CS transitions HIGH while INC is held HIGH. This store command initiates a 10ms internal programming cycle (tWR). During this time, the device draws elevated current and must not be deselected or reset. Once complete, the value persists for 100 years and automatically loads on next power-up - no external commands or power-supply sequencing required.
What is the wiper resistance specification for X9313ZSZ-3 and how does it affect circuit performance?
X9313ZSZ-3 specifies wiper resistance RW as 40Ω typical at VCC = 5V (max 100Ω). This low on-resistance minimizes gain error and thermal noise in precision voltage dividers and feedback networks. When used with 1kΩ RTOTAL, RW contributes <10% of total resistance uncertainty - critical for maintaining linearity and minimizing loading effects on high-impedance nodes like op-amp inputs.
