TSC2003IPWG4

Overview

The TSC2003IPWG4 is a resistive touch screen controller manufactured by Texas Instruments, designed for low-power applications. It features a 12-bit analog-to-digital converter with a sampling rate of up to 125 kS/s. The device supports I2C and SPI serial interfaces, allowing flexible connectivity with host processors. Operating within a voltage range of 2.5 V to 5.25 V, it draws minimal current, making it suitable for battery-powered systems. The component is housed in a 16-pin TSSOP package and operates reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrated 12-bit ADC with 125 kS/s sampling rate
• Dual interface support: I2C and Serial (SPI)
• Low power consumption optimized for portable devices
• Wide supply voltage operation from 2.5 V to 5.25 V

Applications

• Handheld mobile phones and smartphones
• Personal Digital Assistants (PDAs)
• Portable media players
• Industrial control panels with resistive screens

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the package type is TSSOP-16 and ensure the operating temperature range meets the environmental requirements of the target application before procurement.

Selection Notes

Select this component when a resistive touch interface requires both I2C and SPI compatibility. Ensure the host system can handle the 12-bit resolution and that the supply voltage aligns with the 2.5 V to 5.25 V operational window. Consider the TSSOP-16 footprint constraints during PCB layout design.

Part Context

The TSC2003 belongs to the TSC200x family of touch screen controllers from Texas Instruments. This series is engineered for cost-effective and space-constrained embedded systems requiring precise coordinate detection. The IPWG4 variant specifically denotes the industrial temperature grade and tube packaging format.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the TSC2004 and TSC2005, which offer similar functionality but may differ in interface options or additional features like keypad scanning. Verify electrical parameters against the original design specifications.
