TSC2020IRTVT

Overview

The TSC2020IRTVT is a Texas Instruments analog matrix touch screen controller designed for low-power, handheld applications. It supports up to a 3.5-inch sensor with a 3x5 multiple-touch resolution and 12-bit global resolution. The device operates on a single supply voltage ranging from 1.6V to 3.6V. It features an I2C serial interface supporting standard, fast, and high-speed modes. Power consumption is specified at 70.72µW at 1.6V (8.2kSPS equivalent rate) and 87.5µW at 1.8V under similar conditions. The component is housed in a 32-pin WQFN RTV package and is characterized for operation between -40°C and +85°C.

Procurement Notes

Verify the specific ordering suffix 'TV' corresponds to the 250-unit tape and reel packaging configuration as defined in the manufacturer's documentation. Confirm that the active status of the device aligns with current production schedules before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring simultaneous multi-touch detection on analog matrix screens up to 3.5 inches. Ensure the host processor supports the required I2C communication speeds and that the system power budget accommodates the specified operating voltage range of 1.6V to 3.6V.

Part Context

This part belongs to the TSC2020 family of analog matrix touch screen controllers. It is specifically engineered for portable electronics where low power consumption and multi-touch capabilities are critical. The device integrates sensor drivers, control logic, and a 12-bit ADC to measure touch pressure and coordinates.

Replacement Considerations

Consult the official datasheet for alternative packages or variants within the TSC2020 family. Verify pin compatibility and software register mappings if substituting with other resistive touch controllers.
