Point-of-sale terminals

Procurement Notes

The SX8656IWLTRT is listed as obsolete or end-of-life by the manufacturer. Availability is limited, and distributors may not stock this item. Verification of lifecycle status and alternative sourcing is required before procurement planning.

Selection Notes

Select this component only if a 4-wire or 5-wire resistive interface is required with I2C connectivity. Ensure the system power supply stays within 2.3 V to 3.6 V. Consider that the part is obsolete; verify if newer Semtech models support similar resistive touch functionality with active production status.

Part Context

This part belongs to the Semtech SX8656 series of touch controllers. It is designed specifically for resistive technologies, distinguishing it from capacitive touch solutions in the same family. The WLTRT suffix indicates the specific tape-and-reel packaging variant.

Replacement Considerations

As the part is obsolete, direct substitutes are not publicly confirmed. Review Semtech's current portfolio for updated resistive touch controllers or evaluate compatible components from other manufacturers that match the 12-bit resolution and I2C interface requirements.
