Product details
Overview
X9315TMZ-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 3-wire serial interface (CS/U/D/INC). It operates from 2.7V to 5.5V, delivers 100kΩ end-to-end resistance ±20%, and supports commercial temperature range (0°C to +70°C) in an 8-lead MSOP package. It functions as a solid-state replacement for mechanical potentiometers in precision analog trimming applications.
For engineers reviewing the X9315TMZ-2.7T1 datasheet, X9315TMZ-2.7T1 pinout, X9315TMZ-2.7T1 application, or X9315TMZ-2.7T1 equivalent, this device offers verified low-power operation (80µA active, 5µA standby), temperature-compensated linearity (±1 MI absolute, ±0.2 MI relative), and RoHS-compliant Pb-free packaging - critical for embedded control, sensor calibration, and power supply feedback loop tuning.
Technical Context
The X9315TMZ-2.7T1 integrates a 5-bit up/down counter, nonvolatile memory for wiper position retention, and a 31-resistor ladder with make-before-break wiper switching. Its control logic responds to negative-edge-triggered INC pulses under CS enable, with U/D determining increment/decrement direction.
Wiper position is stored to EEPROM only when CS transitions HIGH while INC is HIGH (tWR = 5–10 ms), ensuring deterministic nonvolatile update. The device maintains wiper state across power cycles and exhibits ratiometric temperature coefficient of ±20 ppm/°C - enabling stable voltage-divider performance independent of supply drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 100kΩ ±20% - defines full-scale adjustment range for voltage divider or current-limiting configurations |
| Supply voltage range | 2.7V to 5.5V - enables direct compatibility with 3.3V and 5V systems without level-shifting |
| Active supply current | 80µA max at VCC = 5V - supports battery-powered or low-quiescent-current designs |
| Standby supply current | 5µA max - minimizes system leakage during idle periods |
| Wiper resistance | 400Ω to 1000Ω at VCC = 2.7V - impacts signal integrity and loading in high-impedance feedback paths |
| Nonvolatile endurance | 100,000 data changes per bit - ensures long-term reliability in field-adjustable calibration systems |
| Temperature coefficient | ±300 ppm/°C (RTOTAL), ±20 ppm/°C (ratiometric) - guarantees stable gain/offset over 0°C to +70°C operating range |
Pinout & Package
Package: 8-lead MSOP (Pb-free), JEDEC MO-187BA compliant, dimensions 3.0mm × 3.0mm × 0.85mm (M8.118 drawing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and resistor array; 2.7V–5.5V operation |
| VSS | Ground reference | Common return for all signals; establishes 0V reference for RH/VH, RL/VL, and RW/VW terminals |
| RH/VH | High terminal | Fixed end of resistor array; voltage range 0V to VCC; used as top rail in voltage divider |
| RL/VL | Low terminal | Fixed end of resistor array; voltage range 0V to VCC; used as bottom rail in voltage divider |
| RW/VW | Wiper terminal | Movable contact point; outputs interpolated voltage between RH/VH and RL/VL; series resistance 400–1000Ω at 2.7V |
| CS | Chip select | Active-low enable; initiates wiper movement when LOW; triggers nonvolatile store on HIGH transition with INC = HIGH |
| U/D | Up/down direction control | Logic level sets wiper movement direction during INC pulses; no effect when CS is HIGH |
| INC | Increment clock input | Negative-edge-triggered; advances wiper one tap per pulse; must be HIGH during CS HIGH-to-LOW for store operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ100 | 2-channel, I²C interface, 100kΩ, ±30% RTOTAL tolerance, 128 taps | Requires I²C host; higher resolution but looser resistance tolerance affects absolute accuracy | Select for multi-channel trimming or when I²C infrastructure already exists; avoid if single-channel 3-wire simplicity is required |
| MCP41010-I/P | Single-channel, SPI interface, 10kΩ, ±20% RTOTAL, 257 taps, 5V-only supply | Higher resolution but incompatible 5V-only supply and SPI protocol increase MCU resource usage | Choose for finer granularity in 5V systems; reject for 2.7V operation or minimal GPIO count constraints |
Compared with AD5243BRMZ100 and MCP41010-I/P, the X9315TMZ-2.7T1 uniquely balances ultra-low standby current (5µA), wide 2.7V–5.5V supply range, and minimal 3-pin control - making it optimal for single-channel, low-power, voltage-flexible trimming where deterministic nonvolatile store timing and ratiometric stability are essential.

FAQ
What is the maximum wiper current rating for the X9315TMZ-2.7T1?
The X9315TMZ-2.7T1 has a maximum wiper current rating of ±3.75mA under recommended operating conditions. This limit ensures safe operation without exceeding the 10mW maximum power rating or causing irreversible resistance drift in the 31-element resistor array. Exceeding this current may degrade linearity or shorten nonvolatile memory endurance.
Does the X9315TMZ-2.7T1 retain its wiper position after power loss?
Yes, the X9315TMZ-2.7T1 stores the wiper position in nonvolatile memory and recalls it automatically on power-up. This behavior is guaranteed by the device's EEPROM architecture, which provides 100-year data retention and 100,000 write cycles - ensuring reliable factory calibration persistence across decades of field operation.
Can the X9315TMZ-2.7T1 operate from a 3.3V supply?
Yes, the X9315TMZ-2.7T1 is fully specified for operation from 2.7V to 5.5V, making it compatible with standard 3.3V logic systems. At 3.3V, its active current remains ≤80µA, standby current ≤5µA, and wiper resistance falls within the 400Ω–1000Ω range - preserving signal integrity in low-voltage analog paths.
What is the meaning of "TMZ" in the X9315TMZ-2.7T1 part number?
In the X9315TMZ-2.7T1 part number, "TMZ" denotes the 100kΩ end-to-end resistance variant in Pb-free 8-lead MSOP packaging. The "-2.7" suffix confirms extended 2.7V–5.5V supply capability, and "T1" indicates tape-and-reel packaging per Intersil's reel specification TB347 - distinguishing it from bulk or cut-tape variants.
How does the X9315TMZ-2.7T1 achieve temperature-stable voltage division?
The X9315TMZ-2.7T1 achieves temperature-stable voltage division through a ratiometric temperature coefficient of ±20 ppm/°C - meaning the ratio of wiper voltage to end-to-end voltage remains nearly constant over temperature. This is enabled by matched resistor element TCs and proprietary layout techniques, not by absolute resistance stability (±300 ppm/°C).
