Product details
Overview
X9313ZMZ-3T1 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 1kΩ end-to-end resistance, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage range, and nonvolatile wiper position storage. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications requiring power-up recall and low-power operation.
For engineers reviewing the X9313ZMZ-3T1 datasheet, X9313ZMZ-3T1 pinout, X9313ZMZ-3T1 application, or X9313ZMZ-3T1 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases, and confirmed alternative options for analog signal conditioning, sensor calibration, and programmable gain control circuits.
Technical Context
The X9313ZMZ-3T1 implements a 31-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 5-bit up/down counter decodes to select one of 32 wiper positions, with nonvolatile memory storing the last position for automatic recall at power-up.
Control logic operates via three dedicated inputs: CS enables device selection, U/D sets direction, and edge-triggered INC advances the wiper. A store operation occurs only when CS rises while INC is high-ensuring intentional, not accidental, memory writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 1kΩ ±20% - defines full-scale adjustment range and current-handling capability in voltage divider or variable resistor configurations |
| Wiper resolution | 32 taps - provides 3.125% step resolution per tap, enabling fine-grained analog parameter tuning |
| Supply voltage range | 3V to 5.5V - supports dual-rail compatibility with both 3.3V and 5V logic systems without level-shifting |
| Terminal voltage range | −VCC to +VCC - allows bidirectional signal handling (e.g., ±5V or ±3.3V rails) without external clamping |
| Wiper resistance | 40Ω typical at VCC = 5V - minimizes insertion error in precision voltage division and ensures predictable loading effects |
| Nonvolatile endurance | 100,000 data changes per bit - guarantees long-term reliability for field-adjustable calibration routines |
| Data retention | 100 years - maintains factory or user-set trim values across product lifetime without battery backup |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA, body size 3.0mm × 3.0mm × 0.95mm, pitch 0.65mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal CMOS logic and resistor array; must be stable before asserting CS |
| VSS | Ground reference | System ground return; establishes 0V reference for all analog and digital signals |
| RH/VH | High terminal | Fixed end of resistor array; connects to higher-potential node in voltage divider or current path |
| RL/VL | Low terminal | Fixed end of resistor array; connects to lower-potential node (e.g., VSS or negative rail) |
| RW/VW | Wiper output | Movable tap point; delivers intermediate voltage or resistance; series resistance ~40Ω affects accuracy at high frequencies |
| CS | Chip select | Active-low enable; initiates communication; rising edge with INC=HIGH triggers nonvolatile store |
| U/D | Direction control | Logic level determines wiper movement direction during INC transitions; held stable during increment/decrement cycles |
| INC | Increment clock | Negative-edge triggered; each pulse moves wiper one tap; timing min. 1µs HIGH/LOW periods required |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, vibration sensitivity, and contact noise-enabling >100k cycle life in automated test equipment |
| 3-wire serial interface | Requires only three GPIOs (CS/U/D/INC); no SPI/I²C controller needed-reduces MCU pin count and firmware overhead |
| Power-up wiper recall | Automatically restores last stored position at VCC ramp completion (~10µs after stable supply), ensuring deterministic startup behavior |
| Temperature-compensated array | ±300 ppm/°C end-to-end resistance drift and ±20 ppm/°C ratiometric stability preserve gain/offset accuracy over −40°C to +70°C |
| Low standby current | 500µA max at VCC = 5V - extends battery life in portable instrumentation and sensor nodes between adjustments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ-10 | I²C interface, dual-channel, 10kΩ, 256 taps, 1.8V–5.5V supply | Higher resolution but requires I²C bus and occupies more PCB area; lacks ±VCC terminal voltage support | Select when multi-channel coordination or finer resolution is critical and I²C infrastructure exists |
| MCP41010-I/P | Single-channel SPI interface, 10kΩ, 257 taps, 2.7V–5.5V supply, volatile memory only | No nonvolatile storage-requires host MCU to reinitialize wiper on every power-up; no ±VCC terminal rating | Select for cost-sensitive, high-volume designs where power-up state is managed externally |
Compared with AD5243BRMZ-10 and MCP41010-I/P, the X9313ZMZ-3T1 uniquely combines 3-wire simplicity, ±VCC analog tolerance, and guaranteed power-up recall in a compact MSOP package-making it optimal for robust, self-contained analog trimming where bus overhead and external initialization are unacceptable.

FAQ
What is the maximum allowable voltage across RH/VH and RL/VL terminals for X9313ZMZ-3T1?
The X9313ZMZ-3T1 supports a maximum differential voltage of 4V across RH/VH and RL/VL terminals, as specified in the Absolute Maximum Ratings table. This limit applies regardless of VCC level and ensures safe operation within the 1kΩ end-to-end resistance range. Exceeding 4V risks irreversible damage to the internal resistor array switches.
Does X9313ZMZ-3T1 require an external pull-up resistor on the INC pin?
No, the X9313ZMZ-3T1 does not require an external pull-up on the INC pin. Its input leakage current is ±10µA over the full operating range, and the datasheet specifies VIH ≥ 2V and VIL ≤ 0.8V-indicating standard CMOS-compatible logic thresholds. A clean digital signal from an MCU GPIO suffices without additional biasing.
Can X9313ZMZ-3T1 operate with a 3.3V supply while handling ±3.3V analog signals?
Yes, X9313ZMZ-3T1 supports VCC = 3V to 5.5V and allows terminal voltages from −VCC to +VCC. With VCC = 3.3V, RH/VH and RL/VL may swing from −3.3V to +3.3V, fully accommodating ±3.3V analog signals without clipping or damage-provided the 4V ΔV limit between terminals is observed.
How long does it take for X9313ZMZ-3T1 to stabilize its wiper output after power-up?
The X9313ZMZ-3T1 achieves wiper output stability within 10µs after VCC reaches its final value, as specified in the tPU (Power-up to Wiper Stable) parameter. This fast settling enables immediate use in time-critical analog paths post-power-on, without waiting for extended initialization sequences.
Is the wiper resistance of X9313ZMZ-3T1 constant across all tap positions?
Yes, the wiper resistance of X9313ZMZ-3T1 is approximately constant at 40Ω (typical) across all 32 tap positions when VCC = 5V. This consistency is confirmed in the Potentiometer Characteristics table under RW (Wiper Resistance), ensuring predictable insertion loss and minimal position-dependent loading in precision divider applications.
