I

• 1.8V IO-logic level for SDA and SCL

• I/O-pins are open drain type and logic high level is set with external pull-up resistor

• SFH 7770 operates always as slave, address is 0x38.

• Designed for the I

• Combined format (see I

• Block READ and WRITE modes are available. In these modes several registers can be read or written

during single I

the stop condition. E.g. if master uses block read and starts from register 0x8C, the slave returns

following register values: 0x8C, 0x8D, 0x8E, 0x8F, 0x90, 0x91, 0x92, 0x93, 0x94 and so on until the

master sends stop condition.

• Interrupt pin (INT): open-drain output (like SDA and SCL)
