TSC2008IYZGR

Overview

The TSC2008IYZGR is a nano-power touch screen controller manufactured by Texas Instruments. It supports resistive touch screens with an input type of 1 Touch Screen Controller (TSC) and wiper functionality. The device offers a sampling rate of 250 kS/s and provides 12-bit resolution for precise coordinate detection. It interfaces via Serial, 3-Wire, SPI, and SSI protocols. Operating within a supply voltage range of 1.65 V to 3.6 V, it draws a maximum operating supply current of 285 uA. The component is designed for surface mount installation in a DSBGA-12 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• High-speed sampling rate of 250 kS/s with 12-bit resolution
• Ultra-low power consumption with 285 uA operating supply current
• Supports multiple serial interfaces including SPI and SSI
• Integrated wiper functionality for resistive touch applications

Applications

• Portable handheld devices requiring low power touch input
• Industrial control panels with resistive touchscreens
• Medical equipment with sealed interface requirements

Procurement Notes

Verify the specific suffix 'IYZGR' against the official Texas Instruments datasheet to confirm the exact package variant, temperature grade, and tape-and-reel quantity. Ensure compatibility with the target system's voltage levels and serial communication protocol settings before integration.

Selection Notes

Select this component when a high sampling rate of 250 kS/s is required alongside minimal power consumption. It is suitable for systems utilizing SPI or SSI interfaces rather than I2C. Confirm that the DSBGA-12 package footprint matches the PCB layout constraints and that the 1.65 V to 3.6 V supply range aligns with the system power rails.

Part Context

This part belongs to the TSC200x series of nano-power touch screen controllers from Texas Instruments. These devices are engineered for battery-operated portable electronics where power efficiency and accurate touch positioning are critical. The series typically includes variants with different interface options and package sizes to suit diverse design requirements.

Replacement Considerations

Direct replacements within the same family include other TSC200x variants such as TSC2007 or TSC2004, provided the interface differences (e.g., I2C vs. SPI/SSI) are accommodated in the software driver. Verify pinout compatibility and register mapping before substituting.
