PROGRAMMABLE TOUCH SCREEN CONTROLLER WITH INTEGRATED
STEREO AUDIO CODEC AND HEADPHONE/SPEAKER AMPLIFIER
FEATURES
D
Integrated Touch Screen Processor With
Fully Automated Modes of Operation
DESCRIPTION
The TSC2100 is a highly integrated touch screen
controller with on-chip processor and audio codec. The
touch screen portion of the TSC2100 contains a 12-bit
4-wire resistive touch screen ADC complete with drivers,
and interfaces to the host controller through a standard
SPI錚?serial 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 TSC2100 includes a high-performance audio codec
with 16/20/24/32-bit 97-dB stereo playback, mono record
functionality at up to 48 ksps. A microphone input includes
built-in preamp and hardware automatic gain control, with
single-ended or fully-differential input capability. The dual
output drivers on the TSC2100 can be programmed for low
or high power drive for optimized power saving capability.
The drivers can function as a stereo line-level output, a
stereo headphone amplifier with capless or ac-coupled
configurations, or a bridge-terminated speaker driver,
delivering up to 325 mW into an 8-鈩?load. A programmable
digital audio effects processor enables bass, treble,
midrange, or equalization playback processing. The digital
audio data format is programmable to work with popular
audio standard protocols (I
2
S, DSP, Left/Right Justified) in
master or slave mode, and also includes an on-chip
programmable PLL for flexible clock generation capability.
Highly configurable software power control is provided,
enabling stereo audio playback at 48 ksps at 11 mW with
a 3.3-V analog supply level.
The TSC2100 offers a 12-bit measurement ADC and
internal reference voltage, as well as two battery
measurement inputs capable of reading battery voltages
up to 6 V, while operating at an analog supply as low as
2.7 V. It includes an on-chip temperature sensor capable
of reading 0.3擄C resolution. The TSC2100 is available in
a 32 lead TSSOP and a 32 lead QFN.
