Overview
The TSC2000IPWG4 is a resistive touch screen controller manufactured by Texas Instruments, designed for portable applications requiring low power consumption. It integrates a 12-bit analog-to-digital converter (ADC) capable of sampling at rates up to 125 kS/s. The device supports serial communication via SPI and 3-wire interfaces, operating within a supply voltage range of 3.0 V to 5.5 V. Packaged in a 16-pin TSSOP, it functions as a complete solution for digitizing touch coordinates and pressure data from four-wire resistive screens.
Feature Summary
- Integrated 12-bit ADC with programmable conversion speeds up to 125 kS/s
- Supports SPI and 3-wire serial interface protocols for digital output
- Low power operation with typical supply current of 80 µA
- Includes internal reference voltage and temperature sensor
Applications
- Handheld mobile devices and PDAs
- Portable medical instruments
- Industrial control panels with resistive displays
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards when sourcing. Confirm package availability in tubes versus reels, as the IPW variant typically ships in tubes. Ensure the target system voltage aligns with the 3.0 V to 5.5 V operational range specified for this component.
Selection Notes
Select the TSC2000IPWG4 when a dedicated resistive touch interface with integrated ADC is required without external components. Compare against the TSC2046 if I2C compatibility is preferred over SPI/3-wire. Consider the TSC2007 if additional keypad scanning capabilities are needed alongside touch functionality.
Part Context
This component belongs to the TSC2000 family of touch screen controllers from Texas Instruments. It serves as a foundational model for integrating resistive touch input into embedded systems. The IPWG4 designation specifies the industrial temperature grade, TSSOP-16 package, and green/RoHS-compliant packaging materials.
Replacement Considerations
The TSC2000IPW is the non-green equivalent. For I2C-based designs, the TSC2046 or TSC2007 may serve as functional alternatives with similar performance characteristics but different interface protocols.
