Description



Features:

· 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 evel,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 9397 750 04055 optimal for portable and battery powered applications
· Maximum operating current 25 mA
· 10 general purpose IO pins


Application

· Handheld Personal Computers, Personal Intelligent Communicators, Personal Digital Assistants

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. Parameters are valid over the ambient operating temperature unless otherwise specified. All voltages are with espect to VSSD (pin 37), unless otherwise noted.



Description

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.
