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 programmed 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.

The SSC’s high-level of programmability and its use of DMA permit a continuous high bit rate data transfer without
processor intervention.

Featuring connection to two PDC channels and connection to the DMA, the SSC permits interfacing with low pro-
cessor 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 (with CODECs in 

Master or Slave Modes, I

S, TDM Buses, Magnetic Card Reader,...)

• Contains an independent receiver and transmitter and a common clock divider

• Offers a configurable frame sync and data length

• Receiver and transmitter can be programmed to start automatically or on detection of different event on the 

frame sync signal

• Receiver and transmitter include a data signal, a clock signal and a frame synchronization signal
