TSC2301IPAG

Overview

The TSC2301IPAG is a highly integrated analog interface circuit designed for personal digital assistants and mobile devices. It combines a resistive touch screen controller with a stereo audio codec. The device features an SPI serial interface for host communication and supports programmable resolutions of 8, 10, or 12 bits for the touch screen ADC, with sampling rates up to 125 kHz. The audio section includes a 20-bit delta-sigma ADC/DAC with a dynamic range of 98 dB and sampling rates up to 48 kHz. It operates on a single supply voltage ranging from 2.7 V to 3.6 V and is housed in a 64-lead TQFP package.

Feature Summary

• Integrated Resistive Touch Screen Controller with programmable resolution (8/10/12-bit) and sampling rates up to 125 kHz
• Stereo Audio Codec featuring 20-bit Delta-Sigma ADC/DAC, I2S interface, and 98 dB dynamic range
• Built-in peripherals including battery monitors, temperature sensor, 4x4 keypad scanner, and current output DAC
• Standard SPI serial interface for control and data transfer

Applications

• Personal Digital Assistants (PDAs)
• Cellular Phones
• MP3 Players
• Internet Appliances
• Smartphones

Procurement Notes

Verify the ordering suffix 'PAG' corresponds to the Tray packaging format containing 160 units per tray as specified in the Texas Instruments product selection guide. Confirm that the component meets the required operating temperature range of -40°C to +85°C for the intended application environment. Ensure compatibility with the host system's SPI protocol settings.

Selection Notes

Select the TSC2301IPAG when a combined solution for resistive touch input and stereo audio processing is required in space-constrained designs. The device eliminates the need for separate controllers by integrating SAR ADCs for touch coordinates and delta-sigma converters for audio. Consider the 64-pin TQFP package dimensions against available PCB real estate and ensure the host processor supports the necessary SPI clock speeds and I2S audio interfaces.

Part Context

The TSC2301 belongs to the TSC2301 series of analog interface circuits from Texas Instruments. It is specifically engineered to reduce system complexity in handheld devices by merging human interface functions. The IPAG variant denotes the industrial temperature grade version packaged in a TQFP-64 form factor, distinct from the BGA options available in the same family.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Designers should consult the official Texas Instruments product selection guide for compatible alternatives within the TSC2xxx family or similar integrated interface solutions.
