Overview
The TSC2007IYZGT is a nano-power touch screen controller manufactured by Texas Instruments. It features a 12-bit resolution and supports resistive touch screens via a 4-wire interface with an I2C serial connection. The device operates on a supply voltage range of 1.2 V to 3.6 V, drawing a typical operating current of 128 uA. It provides a sampling rate of 154 kS/s and functions within a temperature range of -40°C to +85°C. The component is housed in a 12-DSBGA package.
Feature Summary
- 12-bit resolution for precise touch coordinate detection
- Nano-power operation with 128 uA typical supply current
- Supports 4-wire resistive touch screens with I2C interface
- High-speed sampling rate of 154 kS/s
Applications
- Portable electronic devices requiring low power consumption
- Resistive touch screen interfaces in embedded systems
- Battery-operated handheld instruments
Procurement Notes
Verify the specific suffix 'IYZGT' against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the DSBGA-12 package. Confirm that the I2C address configuration meets system requirements before procurement.
Selection Notes
Select this component when a low-power solution for resistive touch screens is required. The 1.2 V minimum supply voltage allows operation in battery-powered applications. The 12-bit resolution offers higher precision compared to 8-bit alternatives. Verify that the host microcontroller supports the I2C protocol for communication.
Part Context
The TSC2007 belongs to the TSC2000 series of touch screen controllers from Texas Instruments. This series is designed for portable applications where power efficiency is critical. The TSC2007 variant specifically adds I2C interface capability while maintaining the nano-power characteristics of the family.
Replacement Considerations
Compatible substitutes include other members of the TSC2000 series such as the TSC2005 or TSC2006, provided they support the required I2C interface and package type. Verify pinout compatibility and software register mapping before substitution.
