The UCB1200 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 a speaker. The built-in telecom codec can directly be connected to
a DAA and supports high speed modem protocols. The incorporated analog to digital converter and the touch screen
interface provides complete control and read-out of an 4 wire resistive touch screen. The 10 general purpose I/O pins
provide programmable inputs and/or outputs to the system.
The UCB1200 has a serial interface bus (SIB) intended to communicate to the system controller. Both the codec input
data and codec output data and the control register data are multiplexed on this SIB interface.

- 48 pin LQFP (SOT313) small body SMD package and low external component count results in minimal PCB space
requirement
- 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
- 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 can be directly connected to a Data Access
Arrangement (DAA) and includes a built in sidetone suppression circuit
- Complete 4 wire resistive touch screen interface circuit supporting position, pressure and plate resistance
measurements
- 10-bit successive approximation ADC with internal track and hold circuit and analog multiplexer for touch screen
read-out and monitoring of four external high voltage (7.5V) analog voltages
- High speed, 4 wire serial interface data bus (SIB) for communication to the system controller
- 3.3V supply voltage and built in power saving modes make the UCB1200 optimal for portable and battery powered
applications
- Maximum operating current 25 mA
- 10 general purpose IO pins
