Addressing for basic operation
I
• 1.8V IO-logic level for SDA and SCL
• IO-pins are open drain type and logic high level is set with external pull-up resistor
• SFH 5712-1/2 operates always as slave, address is 0x29 (7bits). Bit 0 is used to change between
Address 0x29
Bit
default
• Designed for the I
• see I
• Spikes up to 10 ns are suppressed on SDA & SCL
