TSC2007IPWR

Overview

The TSC2007IPWR is a nano-power, 12-bit resistive touch screen controller manufactured by Texas Instruments. It operates on a single supply voltage ranging from 1.2V to 3.6V and features an I2C serial interface for communication with host processors. The device supports 4-wire resistive touch screens and includes internal preprocessing to reduce bus activity. Key electrical parameters include a maximum operating temperature of +85°C, a minimum operating temperature of -40°C, and an operating supply current of 280 µA. It is housed in a TSSOP-20 package.

Feature Summary

• 12-bit resolution with 20 kS/s sampling rate (8-bit) or 10 kS/s (12-bit)
• I2C compatible interface supporting Standard, Fast, and High-speed modes
• On-chip temperature sensor and touch pressure measurement capability
• Automatic power-down mode triggered by touch release events

Applications

• Portable mobile phones and smartphones
• Personal Digital Assistants (PDAs)
• GPS navigation devices
• Media players and portable audio devices
• Point-of-sale (POS) terminals

Procurement Notes

Verify the suffix 'IPWR' corresponds to the TSSOP-20 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status and check for specific tape-and-reel packaging requirements if applicable. Ensure the supplier provides official datasheets matching the Texas Instruments part number.

Selection Notes

Select this component when a low-power, high-resolution touch controller with I2C connectivity is required. It is suitable for battery-operated devices due to its nano-power consumption and automatic power-down features. Consider the TSSOP-20 package size constraints and ensure the host system supports the I2C protocol speeds supported by the device.

Part Context

The TSC2007 is part of Texas Instruments' dedicated touch screen controller family, designed specifically for resistive touch applications. It integrates signal processing capabilities to offload tasks from the main microcontroller, enhancing system efficiency in handheld and portable electronics.
