Product details
Overview
X9315TMIZ-2.7T1 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 31-element resistor array with 32 wiper tap positions, nonvolatile wiper position storage, and 2.7V–5.5V single-supply operation. It functions as a solid-state three-terminal potentiometer or two-terminal variable resistor in analog signal conditioning, bias adjustment, and calibration circuits requiring stable, repeatable resistance tuning.
For engineers reviewing the X9315TMIZ-2.7T1 datasheet, X9315TMIZ-2.7T1 pinout, X9315TMIZ-2.7T1 application, or X9315TMIZ-2.7T1 equivalent, this device offers verified 100 kΩ end-to-end resistance, -40°C to +85°C industrial temperature range, Pb-free MSOP-8 packaging, low 5 µA standby current, and 100-year data retention - critical for embedded systems requiring power-cycle persistence and long-term reliability.
Technical Context
The X9315TMIZ-2.7T1 uses a 5-bit up/down counter driving a decoder that selects one of 32 wiper positions across a monolithic 31-resistor array. Wiper movement is controlled via asynchronous 3-wire interface (CS, U/D, INC), with "make-before-break" switching ensuring continuity during transitions.
Nonvolatile memory stores the last wiper position upon CS↑/INC↑ edge, enabling automatic recall at power-up. The device operates with rail-to-rail terminal voltage (0 V to VCC), supports ±3.75 mA max wiper current, and exhibits ±20% end-to-end resistance tolerance with ±300 ppm/°C total resistance temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 100 kΩ ±20% - defines full-scale analog adjustment range and sets gain/bias scaling in voltage divider or current-limiting configurations. |
| Supply voltage range | 2.7 V to 5.5 V - enables direct compatibility with 3.3 V and 5 V logic/system rails without level-shifting. |
| Wiper positions | 32 discrete taps - provides 3.125% resolution per step for precise analog trimming in closed-loop calibration. |
| Nonvolatile storage | 100-year data retention, 100,000 write cycles - ensures factory-set or user-tuned values persist across decades and repeated field updates. |
| Operating temperature | -40°C to +85°C - qualified for industrial environments including motor control, sensor interfaces, and outdoor instrumentation. |
| Standby current | 5 µA max - minimizes quiescent power in battery-backed or energy-sensitive applications. |
| Package | 8-lead MSOP (Pb-free, RoHS compliant, M8.118 footprint) - compact surface-mount form factor with 0.65 mm lead pitch for high-density PCB layouts. |
Pinout & Package
Package: 8-lead Mini Small Outline Plastic (MSOP), Pb-free, JEDEC MO-187BA compliant, body dimensions 3.0 mm × 3.0 mm × 0.85 mm (M8.118).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 2.7–5.5 V; powers internal logic, memory, and resistor array; must be ≥ VH, VL, VW at all times. |
| VSS | Ground reference | Return path for supply and signal currents; establishes 0 V reference for RH/VH, RL/VL, and RW/VW terminals. |
| RH/VH | High terminal | Fixed end of resistor array; connects to maximum potential node (e.g., VCC or signal high); voltage range 0–VCC. |
| RL/VL | Low terminal | Fixed end of resistor array; connects to minimum potential node (e.g., VSS or signal low); voltage range 0–VCC. |
| RW/VW | Wiper output | Movable tap point; delivers intermediate voltage/current between RH/VH and RL/VL; series resistance 400–1000 Ω at 2.7 V. |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on rising edge while INC = HIGH. |
| U/D | Direction control | Sets wiper increment/decrement direction during INC toggling; state may change dynamically while CS = LOW. |
| INC | Increment clock | Negative-edge-triggered; advances wiper one position per valid edge; timing min. 4 µs cycle, 1 µs pulse width. |
Key Features
| Feature | Design Value |
|---|---|
| 3-wire serial interface | Requires only CS, U/D, and INC signals - eliminates need for I²C/SPI peripherals and reduces MCU GPIO count. |
| Nonvolatile wiper storage | Automatically recalls last position at power-up - eliminates boot-time reinitialization in safety-critical or unattended systems. |
| Temperature-compensated array | ±20 ppm/°C ratiometric TC - maintains voltage-divider accuracy across temperature without external compensation. |
| Make-before-break switching | Prevents open-circuit transients during wiper movement - avoids signal dropout or glitch in audio, sensor, or feedback paths. |
| Low-power CMOS design | 80 µA active current at 2.7 V - enables integration into always-on subsystems with strict power budgets. |

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 | 2-channel, I²C interface, 10 kΩ, ±30% RTOTAL tolerance, 2.7–5.5 V, 128 taps | Higher resolution but looser resistance tolerance; dual-channel saves board space in multi-parameter systems | Select when I²C bus availability and dual independent pots outweigh need for tighter RTOTAL tolerance and nonvolatile recall. |
| MCP41HV51-103E/ST | Single-channel, SPI interface, 10 kΩ, ±20% RTOTAL, 2.7–5.5 V, 257 taps, 100-year NVM | Higher resolution (257 taps) and same RTOTAL tolerance; requires SPI instead of 3-wire up/down | Choose for finer analog control granularity where SPI is already used; verify host firmware supports SPI protocol overhead. |
Compared with AD5243BRMZ10 and MCP41HV51-103E/ST, the X9315TMIZ-2.7T1 provides deterministic 3-wire timing, guaranteed 100 kΩ value for fixed-gain scaling, and simpler control logic - making it optimal for cost-sensitive industrial calibrators where minimal MCU resource usage and predictable startup behavior are prioritized.

FAQ
What is the exact end-to-end resistance value and tolerance for X9315TMIZ-2.7T1?
The X9315TMIZ-2.7T1 has a nominal end-to-end resistance of 100 kΩ with a tolerance of ±20%, as specified in the ordering information table and confirmed in the Potentiometer Characteristics section of the FN8179 datasheet. This value is fixed for the TMIZ variant and applies across the full -40°C to +85°C operating range.
Does X9315TMIZ-2.7T1 retain its wiper position after power loss?
Yes, the X9315TMIZ-2.7T1 stores the wiper position in nonvolatile memory with 100-year data retention. Upon power-up, the device automatically recalls the last stored position, eliminating the need for initialization code or external memory in systems requiring consistent startup behavior.
What package type and footprint does X9315TMIZ-2.7T1 use?
The X9315TMIZ-2.7T1 uses an 8-lead Mini Small Outline Plastic (MSOP) package, Pb-free and RoHS compliant, with JEDEC MO-187BA outline and M8.118 drawing. Its dimensions are 3.0 mm × 3.0 mm × 0.85 mm, with 0.65 mm lead pitch and exposed pad not present.
Can X9315TMIZ-2.7T1 operate from a 3.3 V supply?
Yes, the X9315TMIZ-2.7T1 supports supply voltages from 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V logic and power rails. Electrical specifications including active current (80 µA typ.), wiper resistance (400–1000 Ω), and noise (-120 dBV) are characterized across this range.
How is the wiper position programmed on X9315TMIZ-2.7T1?
The X9315TMIZ-2.7T1 uses a 3-wire asynchronous interface: CS (active-low chip select), U/D (direction control), and INC (negative-edge-triggered increment clock). With CS LOW, each falling edge on INC moves the wiper one position up or down based on U/D logic level; position is stored to NVM on CS rising edge while INC is HIGH.
