• Manufacturer Part Number: wts701
• Description: Winbond Single-chip Text-to-speech Processor
• Manufacturer: Winbond Electronics Corp America

The WTS701 processor supports analog and digital telephony in various configurations. The WTS701
can be used in digital environments, along with a DSP that controls a CODEC. Therefore, the
WTS701 is configured to operate in slave mode, where the control signals are provided by an external
source, which is usually the DSP. It supports a variety of single channel CODECs, examples of which
are listed in
The CODEC interface is designed to send data in short frame format as well as long frame format.
The channel width is 13 or 16 bits linear, the precision of the output is 10 bits. The operation mode of
the CODEC is configured by the COD configuration register and SCOD command. See subsection
