11 / 98 page Analog Integrated Circuit Device Data Freescale Semiconductor 11 33903/4/5 PIN CONNECTIONS 15 12 12 N/A VCAUX Output VCOLLECTOR Auxiliary Output pin for external path PNP transistor collector 16 13 13 N/A VAUX Output VOUT Auxiliary Output pin for the auxiliary voltage. 17 14 14 N/A MUX-OUT Output Multiplex Output Multiplexed output to be connected to an MCU A/ D input. Selection of the analog parameter available at MUX-OUT is done via the SPI. A switchable internal pull-down resistor is integrated for VDD current sense measurements. 18 15 15 15 I/O-0 Input/Output Input/Output 0 Configurable pin as an input or output, for connection to external circuitry (switched or small load). The voltage level can be read by the SPI and via the MUX output pin. The input can be used as a programmable wake-up input in Low Power mode. In low power, when used as an output, the high side or low side can be activated for a cyclic sense function. 19 16 16 16 DBG Input Debug Input to activate the Debug mode. In Debug mode, no watchdog refresh is necessary. Outside of Debug mode, connection of a resistor between DBG and GND allows the selection of Safe mode functionality. 23 N/A N/A N/A TXD-L2 Input LIN Transmit Data 2 LIN bus transmit data input. Includes an internal pull-up resistor to VDD. 24,31 N/A N/A N/A GND Ground Ground Ground of the IC. 25 N/A N/A N/A RXD-L2 Output LIN Receive Data LIN bus receive data output. 26 N/A N/A N/A LIN2 Input/Output LIN bus LIN bus input output connected to the LIN bus. 36 17 17 N/A 33905D LIN-1 33905S LIN Input/Output LIN bus LIN bus input output connected to the LIN bus. 37 18 18 N/A 33905D TXD-L1 33905S TXD-L Input LIN Transmit Data LIN bus transmit data input. Includes an internal pull-up resistor to VDD. 38 19 19 N/A 33905D RXD-L1 33905S RXD-L Output LIN Receive Data LIN bus receive data output. 39 20 20 N/A VSENSE Input Sense input Direct battery voltage input sense. A serial resistor is required to limit the input current during high voltage transients. 40 21 21 N/A I/O-1 Input/Output Input Output 1 Configurable pin as an input or output, for connection to external circuitry (switched or small load). The voltage level can be read by the SPI and via the MUX output pin. The input can be used as a programmable wake-up input in Low Power mode. Can be used in association with I/O-0 for a cyclic sense function in Low Power mode. 41 22 22 22 RST Output Reset Output (Active LOW) This is the device reset output whose main function is to reset the MCU. This pin has an internal pull-up to VDD. The reset input voltage is also monitored in order to detect external reset and safe conditions. Table 2. 33903/4/5 Pin Definitions (continued) A functional description of each pin can be found in the Functional Pin Description section beginning on page 30.
