GENERAL DESCRIPTION
The UCB1100 is a single chip, integrated mixed signal audio and
telecom codec. The single channel audio codec is designed for
direct connection of a microphone and speaker. The built-in telecom
codec can directly be connected to a DAA and supports high speed
modem protocols. The incorporated 10 bit analogue to digital
converter and the touch screen interface provides complete control
and readout of a connected 4 wire resistive touch screen. The 10
additional general purpose I/O pins provides programmable inputs
and/or outputs to the system.
The UCB1100 has a serial interface bus (SIB) intended to
communicate to the system controller. Both the codec input and
output data and the control register data is multiplexed on this SIB
interface.
APPLICATIONS
Personal Intelligent Communicators
Personal Digital Assistants (PDA)
Screen phones
Smart Phone and smart Fax
Intelligent Communicators
KEY FEATURES
48-pin LQFP (SOT313-2) small body SMD package and low
external component count result in minimal PCB space
requirement.
A 12-bit sigma delta audio codec with programmable sample rate,
input and output voltage levels, capable of connecting directly to
speaker and microphone, including digitally controlled mute,
loopback and clip detection functions
A 14-bit sigma delta telecom codec with programmable sample
rate, including digitally controlled input voltage level, mute,
loopback and clip detection functions. The telecom codec is
intended for direct connection to a DAA (digital access
arrangement) and includes a built-in sidetone suppression circuit.
A complete 4 wire resistive touch screen interface circuit
supporting position, pressure and plate resistance measurements.
A 10-bit successive approximation ADC with internal track and
hold circuit and analogue multiplier for touch screen readout and
monitoring of four external high voltage (7.5V) analogue voltages.
A high speed, 4 wire serial interface data bus (SIB) for
communication to system controller.
A 3.3V supply voltage and built in power saving modes make the
UCB1100 optimal for portable and battery powered applications.
