NUC100 Series DATA SHEET
Publication Release Date: May 31, 2010
- 8 - Revision V1.02
• I 2 C
– Two sets of I 2 C device.
– Master/Slave up to 1Mbit/s ( Fast-mode Plus )
– Bidirectional data transfer between masters and slaves
– Multi-master bus (no central master).
– Arbitration between simultaneously transmitting masters without corruption of serial data on
the bus
– Serial clock synchronization allows devices with different bit rates to communicate via one
serial bus.
– Serial clock synchronization can be used as a handshake mechanism to suspend and resume
serial transfer.
– Programmable clocks allow versatile rate control.
– I2C-bus controllers support multiple address recognition ( two slave address with mask option)
• I 2 S
– Interface with external audio CODEC
– Operate as either master or slave mode
– Capable of handling 8, 16, and 32 bit word sizes
– Mono and stereo audio data supported
– I 2 S and MSB justified data format supported
– Two 8 word FIFO data buffers are provided, one for transmit and one for receive
– Generates interrupt requests when buffer levels cross a programmable boundary
– Support two DMA requests, one for transmit and one for receive
