GENERAL DESCRIPTION
Publication Release Date: August 1998

Revision A1
The Winbond W9330F is an integrated 900 MHz cordless telephone controller. It employs Code
Division Spread Spectrum (CD/SS) technology optimized for low cost, consumer applications while
providing the clarity, distance and security of digital spread spectrum communication.
Targeted as a single chip baseband solution, the W9330F incorporates all digital signal processing
(DSP) and system control functions for the RF module, voice codec and key pad interface, thus
freeing the MPU for other user oriented tasks. Using 1-bit analog to digital conversion (ADC)
technique, signal processings are performed in an extended time domain transformation to allow for
the use of low cost radio modules. Linear RF coding schemes such as FSK, BPSK and MSK are
supported.
Advance built in features include acoustic echo minimization, data encryption, and diversity antenna
control. A proprietary noise reduction scheme can be implemented to correct for low speed multipath
fading found in consumer cordless and wireless local loop applications.
The W9330F is implemented in a low power 3V CMOS process technology. It is contained in a 100-
pin PQFP package. A complete reference design is available for telephone manufacturers for quick
turn development.
