Notes
1. I/OC = CMOS bidirectional; ID = digital input; S = supply; OA = analog output; IC = CMOS input; IA = analog input;
I/OA = analog bidirectional; OC = CMOS output.
2. VSSD (pins 5 and 37) and VSSA1 (pin 18) are connected internally within the UCB1300.
3. SKPRN/SPKRP (pins 8 and 9), TINN/TINP (pins 14 and 15) and TOUTP/TOUTN are differential pairs
4. TEST (pin 13) is connected to an internal pull-down resistor. This pin should be held LOW during normal operation
of the circuit.
5. The not connected pins (pins 6, 19, 31 and 44) are reserved for future applications and should be left floating.
6. SIBDOUT reset state is 1 until the SIB bus is running. SIBDOUT will be active once the SIB bus has started.
