Description



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 unctions
• 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.

NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any conditions other than those described in the Absolute Maximum Rating section of this specification is not implied.
2. This product includes circuitry specially designed for the protection of its internal devices from damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid submitting the UCB1100 to conditions exceeding the maximum ratings.
3. Parameters are valid over the operating ambient temperature unless otherwise specified. All voltages are with respect to the VSSD pin,unless otherwise noted.



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.
