TSC2013QRSARQ1

Overview

The TSC2013QRSARQ1 is a 12-bit, nano-power touchscreen controller designed for automotive applications. It supports four-wire resistive touchscreens and features an I²C interface with selectable resolutions of 10 or 12 bits. The device operates on a single supply voltage ranging from 1.2V to 3.6V and draws a typical supply current of 655 µA. It is housed in a 16-pin QFN package (4x4 mm) with a maximum height of 0.95 mm. The component is qualified to AEC-Q100 standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports 4-wire resistive touchscreen interfaces with selectable 10-bit or 12-bit resolution
• I²C compatible serial interface for communication
• Low power consumption with 655 µA typical supply current
• Wide operating voltage range from 1.2V to 3.6V

Applications

• Automotive infotainment systems
• In-car navigation displays
• Vehicle instrument clusters

Procurement Notes

Verify the specific suffix 'RSARQ1' against the manufacturer's official datasheet to confirm the exact package type, tape-and-reel quantity, and automotive qualification status. Ensure compatibility with the target system's I²C bus voltage levels and timing requirements before procurement.

Selection Notes

Select this component when designing for automotive environments requiring low power consumption and high-resolution touch input. The 1.2V minimum supply voltage allows operation in battery-backed systems. Verify that the PCB layout accommodates the 16-QFN footprint and thermal pad requirements for reliable heat dissipation at high ambient temperatures.

Part Context

This part belongs to the TSC2013-Q1 family of touchscreen controllers from Texas Instruments. It is specifically engineered for automotive grade reliability, distinguishing it from commercial variants through extended temperature ranges and rigorous qualification processes defined by AEC-Q100 standards.

Replacement Considerations

Direct pin-to-pin replacements within the same family include TSC2013QPWRQ1, which utilizes a 16-TSSOP package instead of QFN. Verify interface compatibility and mechanical fit when substituting packages.
