LIN Wake-Up with MCU in Stop Mode 33399 Analog Integrated Circuit Device Data Freescale Semiconductor 9 FUNCTIONAL DESCRIPTION TIMING DIAGRAMS FUNCTIONAL DESCRIPTION INTRODUCTION The 33399 is a Physical Layer component dedicated to automotive LIN sub-bus applications. The 33399 features include speed communication from 1.0 kbps to 20 kbps, up to 60 kbps for Programming Mode, and active bus waveshaping to minimize radiated emission. The device offers three different wake-up capabilities: wake-up from LIN bus, wake-up from the MCU command, and dedicated high voltage wake-up input. The INH output may be used to control an external voltage regulator. FUNCTIONAL PIN DESCRIPTION POWER SUPPLY PIN (VSUP) The VSUP power supply pin is connected to a battery through a serial diode for reverse battery protection. The DC operating voltage is from 7.0 V to 27 V. This pin sustains standard automotive voltage conditions such as 27 V DC during jump-start conditions and 40 V during load dump. To avoid a false bus message, an undervoltage reset circuitry disables the transmission path (from TXD to LIN) when VSUP falls below 7.0 V. Supply current in the Sleep mode is typically 20 µA. This charge-up is achieved by the total system pullup current resistors. In order to guarantee that the rise time is within specification, maximum bus capacitance should not exceed 10 nF with bus total pullup resistance less than 1.0 kΩ. Receiver Characteristics The receiver thresholds are ratiometric with the device supply pin. Typical threshold is 50%, with a hysteresis between 5% and 10% of VSUP. DATA INPUT PIN (TXD) GROUND PIN (GND) In case of a ground disconnection at the module level, the 33399 does not have significant current consumption on the LIN bus pin when in the recessive state. (Less than 100 µA is sourced from LIN bus pin, which creates 100 mV drop voltage from the 1.0 kΩ LIN bus pullup resistor.) For the dominant state, the pullup resistor should always be active. The 33399 handles a ground shift up to 3.0 V when VSUP > 9.0 V. Below 9.0 V VSUP, a ground shift can reduce VSUP value below the minimum VSUP operation of 7.0 V. The TXD input pin is the MCU interface that controls the state of the LIN output. When TXD is LOW, LIN output is LOW; when TXD is HIGH, the LIN output transistor is turned OFF. This pin has an internal 5.0 V internal pullup current source to set the bus in a recessive state in case the MCU is not able to control it; for instance, during system power-up/ power-down. During the Sleep mode, the pullup current source is turned OFF. DATA OUTPUT PIN (RXD) LIN BUS PIN (LIN) The LIN bus pin represents the single-wire bus transmitter and receiver. Transmitter Characteristics The LIN driver is a low-side MOSFET with internal current limitation and thermal shutdown. An internal pullup resistor with a serial diode structure is integrated so no external pullup components are required for the application in a slave node. An additional pullup resistor of 1.0 kΩ must be added when the device is used in the master node. Voltage can go from - 18 V to 40 V without current other than the pullup resistance. The LIN pin exhibits no reverse current from the LIN bus line to VSUP, even in the event of GND shift or VPWR disconnection. LIN thresholds are compatible with the LIN protocol specification. The fall time from recessive to dominant and the rise time from dominant to recessive are controlled to typically 2.0 V/µs. The symmetry between rise and fall time is also guaranteed. When going from dominant to recessive, the bus impedance parasitic capacitor must be charged up to VSUP. The RXD output pin is the MCU interface that reports the state of the LIN bus voltage. LIN HIGH (recessive) is reported by a high level on RXD; LIN LOW (dominant) is reported by a low voltage on RXD. RXD output structure is a CMOS-type push-pull output stage. ENABLE INPUT PIN (EN) The EN pin controls the operation mode of the interface. If EN = logic , the interface is in normal mode, with the transmission path from TXD to LIN and from LIN to RXD both active. If EN = logic , the device is in Sleep mode or low power mode, and no transmission is possible. In Sleep mode, the LIN bus pin is held at VSUP through the bus pullup resistors and pullup current sources. The device can transmit only after being awakened. Refer to the INHIBIT OUTPUT PIN (INH) description on page 11. During Sleep mode, the device is still supplied from the battery voltage (through VSUP pin). Supply current is 20 µA typical. Setting the EN pin to LOW will turn the INH to high impedance. The EN pin has an internal 20 µA pulldown current source to ensure the device is in Sleep mode if EN floats. 33399 10 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION TIMING DIAGRAMS INHIBIT OUTPUT PIN (INH) The INH pin controls an external switchable voltage regulator having an inhibit input. This pin is a high-side switch structure to VSUP. When the device is in the Normal mode, the inhibit high-side switch is turned ON and the external voltage regulator is activated. When the device is in Sleep mode, the inhibit switch is turned OFF and disables the voltage regulator (if this feature is used). A wake-up event on the LIN bus line will switch the INH pin to VSUP level. Wake-up output current capability is limited to 280 µA. INH can also drive an external MOSFET connected to an MCU IRQ or XIRQ input to generate an interrupt. See the typical application illustrated in Figure 13, page 15. WAKE INPUT PIN (WAKE) The WAKE pin is a high-voltage input used to wake up the device from Sleep mode. WAKE is usually connected to an external switch in the application. The typical WAKE thresholds are VSUP / 2. The WAKE pin has a special design structure and allows wake-up from both HIGH-to-LOW or LOW-to-HIGH transitions. When entering the Sleep mode, the LIN monitors the state of the WAKE pin and stores it as a reference state. The opposite state of this reference state will be the wake-up event used by the device to re-enter Normal mode. An internal filter is implemented (50 µs typical filtering time delay). The WAKE pin input structure exhibits a high impedance with extremely low input current when voltage at this pin is below 14 V. When voltage at the WAKE pin exceeds 14 V, input current starts to sink into the device. A series resistor should be inserted in order to limit the input current, mainly during transient pulses. Recommended resistor value is 33 kΩ. Important The WAKE pin should not be left open. If the wake-up function is not used, WAKE should be connected to GND to avoid false wake-up. 33399 Analog Integrated Circuit Device Data Freescale Semiconductor 11 FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES As described below and depicted in Figure 10 and Table 5 on page 13, the 33399 has two operational modes, normal and sleep, and one transitional mode, Awake. NORMAL MODE • LIN bus activity • Internal node wake-up (EN pin) • Wake-up from WAKE pin Figures 7, 8, and 9 on page 9 show device application circuit and detail of wake-up operations. This is the normal transmitting and receiving mode. All features are available. Wake-Up from LIN Bus (Awake Transitional Mode) SLEEP MODE In this mode the transmission path is disabled and the device is in low power mode. Supply current from VSUP is 20 µA typical. Wake-up can occur from LIN bus activity, as well as from node internal wake-up through the EN pin and the WAKE input pin. DEVICE POWER-UP (AWAKE TRANSITIONAL MODE) At system power-up (VSUP rises from zero), the 33399 automatically switches into the “Awake” mode (refer to Figure 10 below and Table 5 on page 13. It switches the INH pin in HIGH state to VSUP level. The microcontroller of the application then confirms the Normal mode by setting the EN pin HIGH. A wake-up from the LIN pin switching from recessive to dominant state (switch from VSUP to GND) can occur. This is achieved by a node sending a wake-up frame on the bus. This condition internally wakes up the interface, which switches the INH pin to a HIGH level to enable the voltage regulator. The device switches into the Awake mode. The microcontroller and the complete application power up. The microcontroller must switch the EN pin to a HIGH level to allow the device to leave the Awake mode and turn it into Normal mode in order to allow communication on the bus. Wake-Up from Internal Node Activity (Normal Mode) The application can internally wake up. In this case the microcontroller of the application sets the EN pin in the HIGH state. The device switches into Normal mode. Wake-Up from WAKE Pin (Awake Transitional Mode) DEVICE WAKE-UP EVENTS The device can be awakened from Sleep mode by three wake-up events: The application can wake up with the activation of an external switch. Refer to Table 1, 8-SOICN Pin Definitions on page 3.

PROTECTION AND DIAGNOSIS FEATURES ELECTROSTATIC DISCHARGE (ESD) The 33399 has two Human Body Model ESD values. All pins can handle ± 4.0 kV. The LIN bus pin, with respect to ground, can handle ± 5.0 kV. ELECTROMAGNETIC COMPATIBILITY RADIATED EMISSION ON LIN BUS OUTPUT LINE Radiated emission level on the LIN bus output line is internally limited and reduced by active slew rate control of the output bus driver. Figure 11 shows the results in the frequency range 100 kHz to 2.0 MHz. ELECTROMAGNETIC IMMUNITY (EMI) On the LIN bus pin, the 33399 offers high EMI level from external disturbance occurring at the LIN bus pin in order to guarantee communication during external disturbance. On the WAKE input pin, an internal filter is implemented to reduce false wake-up during external disturbance. NOISE FILTERING Noise filtering is used to protect the electronic module against illegal wake-up spikes on the bus. Integrated receiver filters suppress any high-frequency (HF) noise induced into the bus wires. The cut-off frequency of these filters is a compromise between propagation delay and HF suppression.
