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

The following sections describe the physical pin properties and the timing associated with the physical
interface to the device. Note that all input pins are 3V and 5V tolerant, except for the CS signal
which is only 3V tolerant.
The WTS701 processor can receive its clock from either an external clock source or a crystal
oscillator. The XTAL1 and XTAL2 pins provide the crystal interface to the device. The clock to the
WTS701 processor is configured by a clock configuration register, which must be set by the host
processor during the initialization phase.
crystal oscillator. An external clock can be connected to the WTS701 providing the clock source for
the system, as shown in
