espace.cern.chThe lpGBT I2C master interface is the only master interface permitted to connect on the bus. All front-end ASICs; namely the MPA, the SSA, the CiC, the CBC, must implement an I2C Slave interface. Generation of clock signals on the I2C-bus is always the responsibility of the master device. Figure 1 I2C Bus topology for PS and 2S modules.
CAT24C256 - EEPROM Serial 256-Kb I2C
www.onsemi.comMaster and Slave alternate as either transmitter or receiver. Up to 8 devices may be connected to the bus as determined by the device address inputs A0, A1, and A2. I2C Bus Protocol The I2C bus consists of two ‘wires’, SCL and SDA. The two wires are connected to the VCC supply via pull−up resistors. Master and Slave devices connect to the ...
SC18IS602B - I2C-bus to SPI bridge - NXP
www.nxp.comI2C-bus master device to communicate with any SPI-enabled device. 7.1 I2C-bus interface The I2C-bus uses two wires (SDA and SCL) to transfer information between devices connected to the bus, and it has the following features: • Bidirectional data transfer between masters and slaves • Multi-master bus (no central master)
What is TWI? How to Configure the TWI for I2C …
ww1.microchip.comTWI Master Mode Configuration The master write and read operation flow charts for various application examples may be found in the data sheet. When the master reads the bytes from the slave, the master needs to Not Acknowledge (NACK) the last byte to generate the stop condition. To handle this scenario with the correct timing, it is recommended to

ww1.microchip.comJul 14, 2015 · Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code. For the 24LC16B, this is set as ‘ 1010’ binary for read and write operations. The next three bits of the control byte are the Block Select bits (B2, B1, B0). They are used by the master device to select which of the eight

PCA9548A Low Voltage 8-Channel I2C Switch with Reset ...
www.ti.comThe system master can reset the PCA9548A in the event of a time-out or other improper operation by asserting a low in the RESET input. Similarly, the power-on reset deselects all channels and initializes the I2C/SMBus state machine. Asserting RESET causes the same reset and initialization to occur without powering down the part. This allows ...
