TSC2300IPAGRG4

Overview

The TSC2300IPAGRG4 is a programmable touch screen controller with an integrated audio codec, manufactured by Texas Instruments. It features a 12-bit SAR ADC for resistive touch screens with sampling rates up to 125 kHz and a 20-bit delta-sigma audio codec operating at 48 kHz. The device supports SPI communication and I2S audio interfaces. It operates on a single 2.7 V to 3.6 V supply within a -40°C to +85°C temperature range. Key functions include battery monitoring, keypad scanning, and temperature measurement.

Feature Summary

• Integrated 12-bit SAR ADC with programmable resolution (8/10/12 bits) and sampling rates up to 125 kHz
• 20-bit delta-sigma audio codec with 98 dB dynamic range and 48 kHz sampling rate
• Supports 4-wire resistive touch screens, 4x4 keypads, and dual battery monitors
• Single 2.7 V to 3.6 V power supply with internal oscillator and voltage references

Applications

• Personal Digital Assistants (PDAs)
• Cellular phones and smartphones
• MP3 players and internet appliances

Procurement Notes

Verify the 'GRG' suffix indicates tape and reel packaging when ordering. Confirm the specific revision level matches the design requirements. Check for moisture sensitivity labeling as indicated in standard TI documentation. Ensure the host system supports the required SPI and I2S interface protocols for proper integration.

Selection Notes

Select this component for applications requiring combined touch input and audio processing in a single package. The 64-pin TQFP package is suitable for space-constrained designs. Consider the 125 kHz touch sampling rate for responsive displays and the 20-bit audio quality for high-fidelity sound. Verify that the host microcontroller can handle the SPI clock speeds and I2S data formats specified.

Part Context

The TSC2300IPAGRG4 belongs to the TSC2300 series of analog interface circuits from Texas Instruments. It is designed to reduce host CPU overhead by integrating touch screen control, keypad scanning, and audio codec functions into one highly integrated solution. This consolidation simplifies board layout and reduces component count in portable electronic devices.
