DESCRIPTION
The TSC2101 is a low-power highly integrated high
performance codec and touch screen controller, which
supports stereo audio DAC, mono audio ADC and SAR
ADC.
The TSC2101 features a high-performance audio codec
with 16, 20, 24, or 32-bit stereo playback, mono record
functionality at up to 48 ksps. The device integrates
several analog features such as support for headset
interface, cellular headset interface, microphone interface,
and speaker and receiver drivers. The device supports
auto detection of headset and button press without any
glue logic. The TCS2101 has fully programmable audio.
The digital audio data format is programmable to work with
popular audio standard protocols (I2S, DSP, left/right
justified) in master or slave mode, and also includes an
on-chip PLL for flexible clock generation capability.
The TSC2101 contains a 12-bit 4-wire resistive touch
screen converter complete with drivers, and interfaces to
the host controller through a standard SPIserial
interface. The on-chip processor provides extensive
features specifically designed to reduce host processor
and bus overhead, with capabilities that include fully
automated operating modes, programmable conversion
resolution up to 12 bits, programmable sampling rates up
to 125 kHz, programmable conversion averaging, and
programmable on-chip timing generation.
The TSC2101 offers battery measurement inputs capable
of reading battery voltages up to 6 V, while operating at
only 3 V. It also has an on-chip temperature sensor
capable of reading 0.3°C resolution. The TSC2101 is
available in a 48-lead QFN.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.
