TSC2046EIZQCR

Overview

The TSC2046EIZQCR is a low-voltage touch screen controller manufactured by Texas Instruments. It integrates a 12-bit successive approximation analog-to-digital converter (ADC) and an internal temperature sensor to support four-wire resistive touch screens. The device operates on a single power supply ranging from 2.7 V to 5.25 V, with digital I/O pins rated for voltages between 1.65 V and VCC + 0.5 V. It communicates via a serial interface compatible with standard SPI, QSPI, and MICROWIRE protocols. The component is designed for industrial applications, featuring a wide operating temperature range from -40°C to +85°C.

Feature Summary

12-bit ADC resolution with sampling rates up to 125 kSPS
Integrated internal temperature sensor for environmental compensation
Low-power operation with automatic standby mode triggered by PENIRQ
Compatible with 4-wire resistive touch screens and supports 8-wire configurations

Applications

Industrial human-machine interfaces (HMI)
Portable measurement devices requiring high precision
Embedded systems with limited power budgets

Part Context

This part belongs to the TSC2046 family of touch screen controllers. The 'EI' suffix indicates an extended industrial temperature range (-40°C to +85°C), while 'ZCR' denotes the specific package configuration. It serves as a dedicated solution for converting analog touch coordinates into digital data for microprocessors.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the TSC2046IZQCR (standard commercial grade) or TSC2046IPW variants in different packages. Cross-brand substitutes like the ADS7843 may require software adaptation due to register differences.
