Overview
The TSC2014IYZGR is a resistive touch screen controller manufactured by Texas Instruments. It features a 12-bit resolution and supports sampling rates up to 250 kS/s. The device operates on a supply voltage range of 1.6 V to 3.6 V with an operating supply current of 285 uA. It interfaces via Serial, 3-Wire, SPI, and SSI protocols. The component is housed in a DSBGA-12 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution for precise touch coordinate detection
- High-speed sampling rate of up to 250 kS/s
- Low power consumption with 285 uA operating supply current
- Supports multiple interface protocols including SPI and SSI
Applications
- Resistive touch screen systems in portable electronics
- Industrial control panels requiring low-power touch input
- Embedded devices with serial interface constraints
Procurement Notes
Verify the manufacturer designation as Texas Instruments, as some listings may incorrectly attribute this part to other vendors. Confirm the suffix 'GR' indicates tape-and-reel packaging. Ensure the specific revision matches the required datasheet version for interface timing compatibility.
Selection Notes
Select the TSC2014IYZGR when a 12-bit resolution and high sampling speed are required for resistive touch applications. It is suitable for designs needing SPI or SSI connectivity. Compare against the TSC2007 if I2C interface is preferred instead of serial protocols. Verify voltage levels match the 1.6V to 3.6V operational range.
Part Context
This component belongs to the TSC20xx series of nano-power touch screen controllers from Texas Instruments. It shares architectural similarities with the TSC2005 and TSC2007 but offers higher sampling rates and additional serial interface options like SSI. The DSBGA-12 package provides a compact footprint for space-constrained mobile and industrial designs.
Replacement Considerations
The TSC2007IYZGR is a compatible alternative within the same family, offering similar functionality but utilizing an I2C interface instead of SPI/SSI. The TSC2005IYZLT provides comparable performance with a different pinout and package configuration.
