X9455YV24I-2.7

Overview

The X9455YV24I-2.7 is a dual two-wiper digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, housed in a 24-pin TSSOP package. It integrates two resistor arrays, each containing 256 tap points for 0.4% resolution. The device operates within a supply voltage range of 2.7V to 5.5V and features non-volatile storage for wiper positions, ensuring power-on recall. It supports both a 2-wire serial interface and an Up/Down interface for control. Key electrical specifications include a typical end-to-end resistance of 2.8kΩ, a maximum wiper current of 3mA, and a standby current of less than 20µA.

Feature Summary

• Dual two-wiper solid-state potentiometers with 256 resistor tap points per array
• Non-volatile memory storing up to four wiper positions per wiper with power-on recall
• Flexible control via 2-wire serial interface or Up/Down interface
• Hardware write protect capability via the WP pin

Applications

• Programming bias voltages
• Window comparators
• Three-resistor programmable networks

Procurement Notes

This component is marked as not recommended for new designs and has no recommended replacement listed in official documentation. Verify availability status through authorized distributors, as the part may be discontinued. Ensure compliance with RoHS standards if lead-free versions are required for specific manufacturing processes.

Selection Notes

Select the X9455YV24I-2.7 when a total resistance of 2.8kΩ is required. For other resistance values, consider the X9455TV (100kΩ), X9455UV (50kΩ), or X9455WV (10kΩ) variants. Confirm that the 24-TSSOP package fits the design constraints and that the operating temperature range of -40°C to +85°C meets environmental requirements.

Part Context

The X9455 belongs to the XDCP™ family of digitally controlled potentiometers from Renesas (formerly Intersil). This series offers solid-state alternatives to mechanical potentiometers, providing durability and precise digital adjustment capabilities. The Y suffix specifically denotes the 2.8kΩ resistance version within this product line.

Replacement Considerations

Official documentation states there is no recommended replacement for the X9455. Designers should evaluate parametrically similar dual-channel digital potentiometers with I2C or Up/Down interfaces, ensuring matching resistance, resolution, and package dimensions.
