Renesas X9119TV14Z-2.7

Overview

X9119TV14Z-2.7 from Intersil is a 10-bit (1024-tap), low-power, digitally controlled potentiometer (XDCP™) with 2-wire serial interface, 100kΩ end-to-end resistance, 2.7V to 5.5V supply range, and volatile wiper counter register with four nonvolatile data registers - used for precision gain control in voltage amplifiers and programmable DC reference generation in sensor signal conditioning circuits.

For engineers reviewing the X9119TV14Z-2.7 datasheet, X9119TV14Z-2.7 pinout, X9119TV14Z-2.7 application, or X9119TV14Z-2.7 equivalent, this page delivers verified technical context, validated pin functions, confirmed operating parameters, and real-world use cases aligned to the exact X9119TV14Z-2.7 variant - including its extended 2.7V–5.5V VCC range and commercial temperature grade (0°C to +70°C).

Technical Context

The X9119TV14Z-2.7 implements a monolithic CMOS resistor array of 1023 discrete segments with CMOS-switched wiper access, decoded directly from a 10-bit volatile Wiper Counter Register (WCR). Its 2-wire interface supports read/write/transfer operations to both WCR and four 10-bit nonvolatile data registers (DR0–DR3), enabling persistent storage of up to four distinct wiper positions.

Power-on recall loads DR0 into the WCR, ensuring deterministic startup behavior. Hardware write protection (WP pin) disables nonvolatile writes when asserted low, while address pins A0–A2 allow up to eight devices on a shared bus. The device operates as either a 3-terminal potentiometer (RH/RW/RL) or 2-terminal variable resistor.

FAQ

What is the minimum supply voltage for reliable operation of the X9119TV14Z-2.7?

The X9119TV14Z-2.7 is specified for operation from 2.7V to 5.5V. At 2.7V, wiper resistance rises to 150–300Ω (vs. 40Ω at 5V), and standby current remains below 3µA. All digital and analog functions - including 2-wire communication, nonvolatile writes, and wiper response - are fully guaranteed across this range per FN8162 Rev 5.00.

Does the X9119TV14Z-2.7 support true I²C protocol compliance?

Yes, the X9119TV14Z-2.7 implements a standard 2-wire interface compatible with I²C timing: 400kHz max clock frequency, open-drain SDA with required pull-up, start/stop condition detection, and 9-cycle acknowledge sequence. It responds to slave addresses formed by fixed ID bits (0101) plus user-configurable A2–A0 pins - matching I²C physical layer and transaction semantics.

How many distinct wiper positions can be stored nonvolatily in the X9119TV14Z-2.7?

The X9119TV14Z-2.7 contains four independent 10-bit nonvolatile data registers (DR0–DR3), each capable of storing one full 1024-position wiper value. This allows up to four unique calibration states - for example, DR0 for power-on default, DR1 for high-temp compensation, DR2 for low-temp compensation, and DR3 for user-customized setting - all retained for 100 years.

What happens to the wiper position during power-up of the X9119TV14Z-2.7?

On power-up, the X9119TV14Z-2.7 automatically loads the contents of DR0 into the volatile Wiper Counter Register (WCR), establishing the initial wiper position. This power-on recall occurs within 1ms after VCC stabilizes and is guaranteed regardless of prior WCR state - ensuring repeatable analog behavior without host initialization.

Can the X9119TV14Z-2.7 be used as a two-terminal variable resistor?

Yes, the X9119TV14Z-2.7 supports both 3-terminal potentiometer (RH/RW/RL) and 2-terminal variable resistor configurations. In 2-terminal mode, RH and RW (or RL and RW) are used, effectively creating a digitally adjustable resistance from 0Ω to 100kΩ - commonly applied in gain-setting networks, LED current control, and RC timing circuits.
