NUC140 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)
