Digital Potentiometers datasheet and documents for WMS7201050P

WMS7201050P

Digital Potentiometers Overview

The WMS7201 is a single-channel, non-volatile digital potentiometer featuring 256 taps. It offers end-to-end resistance options of 10kΩ, 50kΩ, and 100kΩ. The device operates within a voltage range of 2.7V to 5.5V and supports industrial temperatures from -40°C to 85°C. It includes four non-volatile memory locations for storing wiper positions, with automatic recall from NVMEM0 upon power-up. Control is managed via a standard SPI interface, allowing direct programming or restoration from memory.

Digital Potentiometers Feature Summary

256-tap resolution with selectable 10kΩ, 50kΩ, or 100kΩ end-to-end resistance
Four non-volatile memory locations (NVMEM0-3) for persistent wiper position storage
SPI serial interface with daisy-chain capability in 10-pin TSSOP package
Selectable output buffer for potentiometer or variable resistor configurations

Digital Potentiometers Applications

Programmable gain amplifiers
Voltage reference trimming
RF amplifier control circuits

Digital Potentiometers Procurement Notes

Verify the specific resistance value suffix required for the application, as the base part number covers 10kΩ, 50kΩ, and 100kΩ variants. Confirm the package type matches the design, particularly if hardware write protect or daisy-chain functionality is needed, which requires the 10-pin TSSOP option. Check datasheet revision status as this document is marked preliminary.

Digital Potentiometers Selection Notes

Select the appropriate resistance value based on load requirements. Ensure the system voltage falls between 2.7V and 5.5V. If hardware write protection is necessary, the 10-pin TSSOP package must be selected due to the dedicated WP pin. Consider the standby current specifications when power efficiency is critical, noting the difference between buffer active and inactive states.

Digital Potentiometers Part Context

The WMS7201 belongs to the Winpot family of non-volatile digital potentiometers manufactured by Winbond. It provides a solid-state alternative to mechanical potentiometers, offering durability and programmability. The device integrates both volatile tap registers and non-volatile memory to maintain settings across power cycles.
