10 / 98 page Analog Integrated Circuit Device Data 10 Freescale Semiconductor 33903/4/5 PIN CONNECTIONS Table 2. 33903/4/5 Pin Definitions A functional description of each pin can be found in the Functional Pin Description section beginning on page 30. Pin # 33905D Pin # 33905S Pin # 33904 Pin # 33903 Pin Name Pin Function Formal Name Definition 1-3,20- 22,27- 30,32- 35,52-54 N/A 17, 18, 19 2-4,11- 13, 17- 21, 31, 32 N/C No Connect - No Connection 4 1 1 1 VSUP1 Power Battery Voltage Supply 1 Supply input for the device internal supplies, power on reset circuitry and the VDD regulator. 5 2 2 2 VSUP2 Power Battery Voltage Supply 2 Supply input for 5 V-CAN regulator, VAUX regulator, I/O and LIN pins. 6 3 3 N/A LIN-T2 or I/O-3 Output or Input/Output LIN Termination 2 or Input/Output 3 33905D, Output pin for the LIN2 master node termination resistor. or 33904/33905S, Configurable pin as an input or high side output, for connection to external circuitry (switched or small load). The input can be used as a programmable wake-up input in Low Power mode. When used as a high side, no over- temperature protection is implemented. A basic short to GND protection function, based on switch drain-source over-voltage detection, is available. 7 4 4 N/A LIN-T1 or LIN-T I/O-2 Output or Input/Output LIN Termination 1 or Input/Output 2 I/O-2 33905D, Output pin for the LIN1 master node termination resistor. or 33905S, 33905D, Configurable pin as an input or high side output, for connection to external circuitry (switched or small load). The input can be used as a programmable wake-up input in Low Power mode. When used as a high side, no over- temperature protection is implemented. A basic short to GND protection function, based on switch drain-source over-voltage detection, is available. 33904, Configurable pin as input or high side output, for connection to external circuitry (switched or small load). Input can be used as a programmable wake-up input from Low Power mode. When used as high side, no over- temperature protection is implemented. A basic short to GND protection function based on switch drain-source over-voltage detection is available. 8 5 5 5 SAFE Output Safe Output (Active LOW) Output of the safe circuitry. The pin is asserted LOW in case of a safe condition is detected (e.g.: software watchdog is not triggered, VDD low, issue on the RESET pin, etc.). Open drain structure. 9 6 6 6 5 V-CAN Output 5V-CAN Output voltage for the embedded CAN interface. A capacitor must be connected to this pin. 10 7 7 7 CANH Output CAN High CAN high output. 11 8 8 8 CANL Output CAN Low CAN low output. 12 9 9 9 GND-CAN Ground GND-CAN Power GND of the embedded CAN interface 13 10 10 10 SPLIT Output SPLIT Output Output pin for connection to the middle point of the split CAN termination 14 11 11 N/A VBAUX Output VB Auxiliary Output pin for external path PNP transistor base |
