SAM3X/A

– Support for two PDC channels with connection to receiver and transmitter

– Connection to Peripheral DMA Controller or DMA Controller (TWI0) Channel

Capabilities Optimizes Data Transfers

12.4 USART

• Programmable Baud Rate Generator

• 5- to 9-bit full-duplex synchronous or asynchronous serial communications

– 1, 1.5 or 2 stop bits in Asynchronous Mode, or 1 or 2 stop bits in Synchronous Mode

– Parity generation and error detection

– Framing error detection, overrun error detection

– MSB- or LSB-first

– Optional break generation and detection

– By 8 or by-16 over-sampling receiver frequency

– Hardware handshaking RTS-CTS

– Receiver time-out and transmitter timeguard

– Optional Multi-drop Mode with address generation and detection

– Optional Manchester Encoding

• RS485 with driver control signal

• ISO7816, T = 0 or T = 1 Protocols for interfacing with smart cards

– NACK handling, error counter with repetition and iteration limit

• SPI Mode

–Master or Slave

– Serial Clock programmable Phase and Polarity

– SPI Serial Clock (SCK) Frequency up to MCK/6

• IrDA modulation and demodulation

– Communication at up to 115.2 Kbps

• LIN Mode (USART0 only)

– Compliant with LIN 1.3 and LIN 2.0 specifications

–Master or Slave

– Processing of frames with up to 256 data bytes

– Response Data length can be configurable or defined automatically by the Identifier

– Self synchronization in Slave node configuration

– Automatic processing and verification of the “Synch Break” and the “Synch Field”

– The “Synch Break” is detected even if it is partially superimposed with a data byte

– Automatic Identifier parity calculation/sending and verification

– Parity sending and verification can be disabled

– Automatic Checksum calculation/sending and verification

– Checksum sending and verification can be disabled

– Support both “Classic” and “Enhanced” checksum types

– Full LIN error checking and reporting

– Frame Slot Mode: the Master allocates slots to the scheduled frames automatically
