Description
Embedded Characteristics
The Atmel 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 pro-
grammed to start automatically or on different events detected on the Frame Sync signal.
The SSC’s 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 Configurable Frame Sync and Data Length
• Receiver and Transmitter Can be Programmed to Start Automatically or on Detection of
• Receiver and Transmitter Include a Data Signal, a Clock Signal and a Frame Synchronization
