Overview
The TSC2046EIRGVR is a resistive touch screen controller manufactured by Texas Instruments, designed for 4-wire touch panel applications. It features a 12-bit resolution and supports sampling rates up to 125 kS/s. The device operates on a supply voltage range of 2.2 V to 5.25 V with a typical operating current of 280 uA. It interfaces via Serial, 3-Wire, SPI, or SSI protocols. Packaged in a 16-VQFN format, it functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- 12-bit resolution ADC for precise touch coordinate detection
- Supports 4-wire resistive touch screens with low voltage digital I/O
- Integrated internal voltage reference simplifies external component requirements
- Multiple serial interface options including SPI and SSI
Applications
- Industrial control panels requiring resistive touch input
- Medical devices needing reliable touch interface solutions
- Consumer electronics utilizing 4-wire resistive displays
Procurement Notes
Verify the specific suffix 'E' indicates the extended or specific grade variant compared to the standard TSC2046 series. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly processes.
Selection Notes
Select this component when a 12-bit resolution is required for 4-wire resistive touch screens. Ensure the system power supply falls within the 2.2 V to 5.25 V range. Verify that the host microcontroller supports the required serial interface protocols (SPI/SSI). Consider the 16-VQFN package size for PCB layout constraints.
Part Context
This part belongs to the TSC2046 family of touch screen controllers from Texas Instruments. It shares core specifications with variants like TSC2046IRGVR but may differ in specific grading or packaging details indicated by the 'E' suffix. It serves as a dedicated solution for converting analog touch signals into digital coordinates.
Replacement Considerations
The TSC2046EIRGVT is a tape-and-reel alternative within the same family. The TSC2046IRGVR is a standard version without the 'E' suffix, potentially differing in quality grade or testing criteria. Verify pin compatibility and electrical parameters before substituting.
