TSC2017IYZGR

Overview

The TSC2017IYZGR is a Texas Instruments resistive touch screen controller featuring a 12-bit analog-to-digital converter and an integrated temperature sensor. It supports multiple serial interfaces, including SPI, I2C, and Microwire, allowing flexible system integration. The device operates on a single power supply ranging from 1.6 V to 3.6 V, with a typical operating current of 500 µA. Designed for surface-mount applications, it utilizes a 28-pin DSBGA package. The component functions within a standard industrial temperature range of -40°C to +85°C, providing precise coordinate tracking and battery voltage measurement capabilities.

Feature Summary

• Integrated 12-bit ADC with up to 125 kS/s sampling rate
• Supports SPI, I2C, and Microwire serial communication protocols
• Built-in temperature sensor for thermal monitoring
• Low power consumption with 500 µA operating current

Applications

• Handheld mobile devices requiring resistive touch input

Procurement Notes

Verify the specific suffix 'GR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the target system's voltage levels and interface protocol requirements before procurement. Cross-reference the full part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a 12-bit resolution is required for accurate touch positioning. Verify that the host processor supports at least one of the supported serial interfaces (SPI, I2C, or Microwire). Confirm that the system power budget accommodates the 1.6 V to 3.6 V operating range and the specified quiescent current.

Part Context

This part belongs to the TSC20xx series of nano-power touch screen controllers from Texas Instruments. These components are designed to replace discrete ADC and interface solutions in compact electronic designs. The series offers various interface options and package sizes to suit different form factors while maintaining low power operation.

Replacement Considerations

Consult the TI TSC20xx family datasheet for direct pin-compatible alternatives such as the TSC2005 or TSC2007. Verify interface compatibility and resolution requirements when substituting with other models in the series.
