Product details
Overview
X9252TV24IZ-2.7 from Renesas Electronics is a quad digitally controlled potentiometer (XDCP™) with 256-tap resolution, 2.8 kΩ end-to-end resistance, 2-wire + Up/Down dual interface support, and nonvolatile data registers for persistent wiper position storage. It operates from 2.7 V to 5.5 V and is used in precision analog trimming, bias voltage programming, and programmable gain control circuits.
For engineers reviewing the X9252TV24IZ-2.7 datasheet, X9252TV24IZ-2.7 pinout, X9252TV24IZ-2.7 application, or X9252TV24IZ-2.7 equivalent, this page delivers verified electrical specs, validated 24-pin TSSOP package mapping, confirmed DCP0–DCP3 terminal assignments, and two rigorously cross-checked alternative parts for industrial trim and calibration designs.
Technical Context
The X9252TV24IZ-2.7 integrates four independent 255-segment resistor arrays, each with dedicated volatile Wiper Counter Registers (WCR0–WCR3) and four nonvolatile Data Registers (DRi0–DRi3). Wiper positioning is controlled via either 2-wire serial bus (I²C-compatible, up to 400 kHz) or discrete Up/Down interface using CS, U/D, DS0, and DS1 pins.
At power-up, DR00, DR10, DR20, and DR30 load into corresponding WCRs; hardware write protection (WP) disables nonvolatile writes when low. Each DCP supports three-terminal potentiometer or two-terminal variable resistor configurations with ±3 mA max wiper current and 40 Ω typical wiper resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | 10 kΩ RTOTAL, I²C-only interface, no Up/Down pins, 24-lead TSSOP | Lacks hardware trim capability; requires MCU firmware for all adjustments | Choose when only I²C control is needed and higher resistance value suits gain-setting topology |
| MCP42010-I/P | 10 kΩ RTOTAL, SPI interface, single DCP, 14-pin PDIP/SOIC, no nonvolatile store | Single-channel only; volatile-only wiper memory requires external microcontroller backup | Choose for cost-sensitive, single-pot applications where SPI is preferred and calibration persistence is handled externally |
Compared with AD5242BRUZ10 and MCP42010-I/P, the X9252TV24IZ-2.7 uniquely combines quad 2.8 kΩ DCPs, dual 2-wire/Up-Down interfaces, and nonvolatile DR storage - making it optimal for industrial systems requiring both firmware-driven calibration and hardware-fallback trim without external memory.

FAQ
What is the end-to-end resistance value of the X9252TV24IZ-2.7?
The X9252TV24IZ-2.7 has a nominal end-to-end resistance (RTOTAL) of 2.8 kΩ, with ±20% tolerance across temperature. This value is fixed per device variant and confirmed in the Absolute Maximum Ratings and Analog Specifications sections of the FN8167 datasheet. The 2.8 kΩ rating directly determines voltage division range and power dissipation limits in applications like bias control and gain setting.
Does the X9252TV24IZ-2.7 support both I²C and discrete Up/Down control simultaneously?
No - the X9252TV24IZ-2.7 supports dual interface modes but not concurrently. When CS is LOW, the Up/Down interface is active and the 2-wire bus is disabled; when CS is HIGH, the 2-wire interface is enabled and Up/Down signals are ignored. This hardware-muxed design prevents bus contention and simplifies system-level interface routing.
How does nonvolatile storage work in the X9252TV24IZ-2.7?
The X9252TV24IZ-2.7 contains four nonvolatile Data Registers (DRi0–DRi3) per DCP, totaling 16 registers. A "Store" operation - triggered by CS rising while SCL and WP are HIGH - copies the current WCR value into the selected DR. WP=LOW blocks all nonvolatile writes. At power-up, DR00–DR30 automatically load into WCR0–WCR3, ensuring repeatable startup behavior.
What is the maximum wiper current rating for the X9252TV24IZ-2.7?
The X9252TV24IZ-2.7 specifies a maximum wiper current (IW) of ±3.0 mA per wiper terminal (RW0–RW3), as defined in the Analog Specifications table on page 4 of FN8167. Exceeding this limit risks long-term resistance drift or wiper switch degradation. Designers must ensure voltage across any DCP segment remains within safe power dissipation (50 mW per DCP).
Can the X9252TV24IZ-2.7 be used as a two-terminal variable resistor?
Yes - each of the four DCPs in the X9252TV24IZ-2.7 can operate as a two-terminal variable resistor by connecting either RH or RL to the wiper (RW), leaving the unused terminal open or tied to a fixed potential. This configuration is explicitly supported in the datasheet's Functional Description and Applications sections and maintains full 256-tap resolution and nonvolatile storage capability.
