TSC2004IYZKR

Overview

The TSC2004IYZKR is a Texas Instruments resistive touch screen controller featuring a 12-bit analog-to-digital converter. It operates on a single supply voltage ranging from 1.65 V to 3.6 V with an operating supply current of 506 uA. The device supports serial communication interfaces including SPI, I2C, and 3-wire modes. It provides 100 kS/s sampling rate for touch position detection. The component is housed in a DSBGA-24 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• 12-bit resolution ADC for precise touch coordinate acquisition
• Low power consumption with 506 uA operating supply current
• Supports multiple serial interfaces: SPI, I2C, and 3-wire
• Integrated battery monitor and temperature sensor

Applications

• Handheld mobile devices
• Personal digital assistants (PDAs)
• Portable medical instruments
• Industrial control panels

Procurement Notes

Verify the suffix 'KR' indicates tape and reel packaging configuration. Confirm the specific grade matches the required operational temperature range of -40°C to +85°C. Ensure compatibility with the target system's voltage levels for the serial interface signals.

Selection Notes

Select this component when a low-power, high-resolution touch controller is required for space-constrained designs. The DSBGA-24 package suits surface-mount applications. Verify that the host processor supports the desired serial protocol (SPI or I2C) for data retrieval.

Part Context

This part belongs to the TSC2000 series of nano-power touch screen controllers. It is designed to replace older, higher-power solutions in portable electronics. The IYZKR variant specifically denotes the industrial temperature range and reel packaging format.

Replacement Considerations

Direct pin-compatible replacements may include other members of the TSC2000 family such as TSC2005 or TSC2006, provided interface configurations are verified. Cross-reference datasheets for any differences in internal reference voltage or sampling rates.
