The Synchronous Serial Controller (SSC) provides a synchronous communication link with external devices. It 

supports many serial synchronous communication protocols generally used in audio and telecom applications 

such as I2S, Short Frame Sync, Long Frame Sync, etc.
The SSC contains an independent receiver and transmitter and a common clock divider. The receiver and the 

transmitter each interface with three signals: the TD/RD signal for data, the TK/RK signal for the clock and the 

TF/RF signal for the Frame Sync. The transfers can be programmed to start automatically or on different events 

detected on the Frame Sync signal.
The SSC high-level of programmability and its two dedicated PDC channels of up to 32 bits permit a continuous 

high bit rate data transfer without processor intervention.
Featuring connection to two PDC channels, the SSC permits interfacing with low processor overhead to the 

following:



CODEC’s in master or slave mode



DAC through dedicated serial interface, particularly I2S



Magnetic card reader



Provides Serial Synchronous Communication Links Used in Audio and Telecom Applications 



Contains an Independent Receiver and Transmitter and a Common Clock Divider



Interfaced with Two PDC Channels (DMA Access) to Reduce Processor Overhead



Offers a Configurable Frame Sync and Data Length



Receiver and Transmitter Can be Programmed to Start Automatically or on Detection of Different Events on 

the Frame Sync Signal



Receiver and Transmitter Include a Data Signal, a Clock Signal and a Frame Synchronization Signal
