The devices are designed for CAN-LIN automotive applications e.g. body controller, gateway applications. To support these applications, the System Basis Chip (SBC) provides the main functions, such as HS-CAN transceiver for data transmission, low dropout voltage regulators (LDO) for an external 5 V supply, and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device. Also implemented are a Time-out or a Window Watchdog circuit with a reset feature, Limp Home circuitry output, and an undervoltage reset feature. The devices offer low power modes in order to support application that are connected permanent to the battery. A wake-up from the low power mode is possible via a message on the buses or via the bi-level sensitive monitoring/wake-up input as well as from the SPI command. Each wake-up source can be inhibited. The device is designed to withstand the severe conditions of automotive applications.

Table 1 SBC Configuration Configuration Description Test pin INT Pin WD to LH bit config 0 Software Development Mode 0V n.a n.a config 1 After missing the WD trigger for the first time, the state of Vcc1µC Open / VS External 0 remain unchanged, LH pin is active, SBC in Restart Mode pull-up config 2 After missing the WD trigger for the first time, Vcc1µC turns OFF, LH pin is active, SBC in Fail-Safe Mode No ext. pull-up config 3 After missing the WD trigger for the second time, the state of Vcc1µC remain unchanged, LH pin is active, SBC in Restart Mode External 1 pull-up config 4 After missing the WD trigger for the second time, Vcc1µC turns OFF, LH pin is active, SBC in Fail-Safe Mode No ext. pull-up 0 1 In SBC SW Development Mode, Config 1 to 4 are accessible. 4.2.2 SBC Power ON Reset (POR) At VS > VUVON, the SBC starts to operate, by reading the test pin and then by turning ON Vcc1µC. When Vcc1µC reaches the reset threshold VRT1, the reset output remains activated for tRD1 and the SBC enters then the Init Mode. In the event that Vs decreases below VUVOFF, the device is completely disabled. For more details on the disable behavior of the SBC blocks, please refer to the chapter specific to each block. 4.2.3 SBC Init Mode At entering the SBC Init Mode, the SBC starts to read the Test pin. The SBC starts-up in SBC Init Mode, and, after powering-up, waits for the microcontroller to finish its startup and initialization sequences. Vcc2/3 are OFF and the Watchdog is configurable but not active. CAN is inactive and Limp Home output is inactive. From this transition mode, the SBC can be switched via SPI command to the desired operating mode, SBC Normal or Software Flash Mode. If the SBC does not receive any SPI command, or receive wrong SPI command (i.e. not send the device to SBC Normal or SBC SW Flash Mode) within a 256 ms time frame after the reset relaxation, it will enter into SBC Restart Mode and activate the Limp Home output. Note: In Init Mode it is recommended to send one SPI command that sets the device to Normal Mode, triggers the watchdog the first time and sets the required watchdog settings. Data Sheet 11 Rev. 1.0, 2009-03-31 TLE8261E State Machine 4.2.4 SBC Normal Mode SBC Normal Mode is used to transmit and receive CAN messages. In this mode, Vcc1µC is always “ON” Vcc2 and Vcc3 can be turned-on or off by SPI command. In Normal Mode the watchdog needs to be triggered. It can be configured via SPI, window watchdog and time-out watchdog is possible (default value is time-out 256 ms). All the wake-up sources can be inhibited in this mode. The Limp Home output can be enabled or disabled via SPI command. Via SPI command, the SBC can enter Sleep, Stop or Software Flash Mode. A reset is triggered by the SBC when entering the Software Flash Mode. It is recommended to send at first SPI command the watchdog setting. Please refer to Chapter 12.4. 4.2.5 SBC Sleep Mode During SBC Sleep Mode, the lowest power consumption is achieved by having the main and external voltage regulators switched-off. As the microcontroller is not supplied, the integrated Watchdog is disabled in Sleep Mode. The last Watchdog configuration is not stored. The CAN module is in Wake-capable or OFF modes and the Limp Home output is unchanged, as before entering the Sleep Mode. If a wake-up appears in this mode, the SBC goes into Restart Mode automatically. In Sleep Mode, not all wake-up sources should be inhibited, this is required to not program the device in a mode where it can not wake up. If all wake sources are inhibited when sending the SBC to Sleep Mode, the SBC does not go to Sleep Mode, the microcontroller is informed via the INT output, and the SPI bit “Fail SPI” is set. The first SPI output data when going to SBC Normal Mode will always indicate the wake up source, as well as the SBC Sleep Mode to indicate where the device comes from and why it left the state. Note: Do not change the transceiver settings in the same SPI command that sends the SBC to Sleep Mode. 4.2.6 SBC Stop Mode The Stop Mode is used as low power mode where the µC is supplied. In this mode the voltage regulator Vcc1µC remains active. The other voltage regulator (Vcc2/3) can be switched on or off. The watchdog can be used or switched off. If the watchdog is used the settings made in Normal Mode are also valid in Stop Mode and can not be changed. The CAN is not active. It can be selected to be off or used as wake-up source. If all wake up sources are disabled, (CAN, WK, cyclic wake) the watchdog can not be disabled, the SBC stays in Normal Mode and the watchdog continues with the old settings. If a wake-up event occurs the INT pin is set to low. The µC can react on the interrupt and set the device into Normal Mode via SPI. There is no automatic transition to SBC Normal Mode. There are 4 Options for SBC Stop Mode • • • • WD on (the watchdog needs to be served as in Normal Mode WD off (special sequence required see Chapter 10.2.4) Cyclic Wake up with acknowledge (interrupt is sent after set time and needs to be acknowledged by SPI read) Cyclic Wake-up, Watchdog off (interrupt is sent after set time) Cyclic Wake-Up Feature SBC Stop Mode supports the cyclic wake-up feature. By default, the function is OFF. It is possible to activate the cyclic wake-up via “Cyclic WK on/off” SPI bit. This feature is useful to monitor battery voltage, for example, during parking of the vehicle or for tracking RF data coming via the RF receiver. The Cyclic Wake-up feature sends an interrupt via the pin INT to the µC after the set time. The cyclic wake-up feature shares the same clock as the Watchdog. The time base set in the SPI for the Watchdog will be used for the cyclic wake-up. The timer has to be set before activating the function. With the cyclic wake-up feature the watchdog is not working as known from the other modes. In the case that both functions (Watchdog and cyclic wake-up) are selected, the cyclic wake-up is activated and each interrupt has to be acknowledged by reading the SPI Wake register before the next Cyclic Wake-Up comes. Otherwise, the SBC goes to SBC Restart Mode. Data Sheet 12 Rev. 1.0, 2009-03-31 TLE8261E State Machine 4.2.7 SBC Software Flash Mode SBC Software Flash Mode is similar to SBC Normal Mode regarding voltage regulators. In this mode, the Limp Home output can be set to active LOW via SPI and the communication on CAN is activated to receive flash data. The Watchdog configuration is fixed to the settings used before entering the SBC SW Flash Mode. When the device comes from SBC Normal Mode, a reset is generated at the transition. From the SBC Software Flash Mode, the SBC goes into SBC Restart Mode, the config setting has no influence on the behavior. A mode change to SBC Restart Mode can be caused by a SPI command, a time-out or Window Watchdog failure or an undervoltage reset. When leaving the SBC Software Flash Mode a reset is generated. 4.2.8 SBC Restart Mode They are multiple reasons to enter the SBC Restart Mode and multiple SBC behaviors described in Table 2. In any case, the purpose of the SBC Restart Mode is to reset the microcontroller. • • • • • From SBC SW Flash Mode, it is used to start the new downloaded code. From SBC Normal, SBC Stop Mode and SBC SW Flash Mode it is reached in case of undervoltage on Vcc1µC, or due to incorrect Watchdog triggering. From SBC Sleep Mode it is used to ramp up Vcc1µC after wake From SBC Init Mode, it is used to avoid the system to remain undefined. From SBC Fail-safe Mode it is used to ramp up Vcc1µC after wake or cool down of Vcc1µC. From SBC Restart Mode, the SBC goes automatically to SBC Normal Mode. The delay time tRDx is programmable by the “Reset delay” SPI bit. The Reset output (RO) is released at the transition. SBC Restart Mode is left automatically by the SBC without any microcontroller influence. The first SPI output data will provide information about the reason for entering Restart Mode. The reason for entering Restart Mode is stored and kept until the microcontroller reads the corresponding “LH0..2” or “RM0..1” SPI bits. In case of a wake up from Sleep Mode the wake source is seen at the interrupt bits (Configuration select 000), an interrupt is not generated. Entering or leaving the SBC Restart Mode will not result in deactivation of the Limp Home output (if activated). The first SPI output data when going to SBC Normal Mode will always indicate the reason for the SBC Restart event.

The Limp Home output is active. Conditions to enter the SBC Fail-Safe Mode are: • • • • Watchdog trigger failure in configuration 2 or 4 Vcc1µC undervoltage time-out in any configuration if VS is above VLHUV range. Temperature shutdown of Vcc1µC in any configuration. Reset clamped in Config. 2/4 In case of Vcc1µC overtemperature shutdown, the SBC will latch and wait to cool down below the thermal hysteresis, and will go back to SBC Restart Mode. In case of a wake-up event, the SBC will go to SBC Restart Mode (not in case of Vcc1µC overtemperature shutdown), storing the wake-up event and resetting the Watchdog trigger failure counter. The first SPI output data when going to SBC Normal Mode will always indicate the reason for the SBC Fail-Safe Mode. 4.2.10 SBC Software Development Mode If the Test pin is connected to GND (Config 0 active) during powering-up, the SBC enters SBC Software Development Mode. SBC Software Development Mode is a super set of the other modes so it is possible to use all the modes of the SBC with the following difference. In SBC Software Development Mode, no reset is generated and VCC1µC is not switched off due to Watchdog trigger failure. If a Watchdog trigger failure occurs, it will be indicated by the INT output (reset bit). The SBC Fail-Safe Mode or SBC Restart Mode are not reached in case of wrong Watchdog trigger but the other reasons to enter these modes are still valid. 4.2.11 SBC Factory Flash Mode In this mode, the SBC is completely powered OFF and the microcontroller is supplied externally. The mode is detected when VCC1µC is powered from external and the voltage on Vs is not powered from external. The current flow out of Vs must be limited to the maximum rating. The external supply voltage should be below the absolute maximum rating stated in Chapter 5.1. The reset can be driven by an external circuit, or pulled high with a pull-up resistor. Note: Please respect the absolute maximum ratings when the device is in SBC Factory Flash Mode.

V S D GND Figure 4 Functional Block Diagram The internal voltage regulators are dual low-drop voltage regulators that can supply loads up to ICC1µC/2_max. An input voltage up to VSMAX is regulated to Vcc1µC/2_nom = 5.0 V with a precision of ±2%. Due to its integrated reset circuitry, featuring two SPI configurable power-on timing (tRDx) and three SPI configurable output voltages (VRTx) monitoring, the device is well suited for microcontroller supply. The design enables stable operation even with ceramic output capacitors down to 470nF, with ESR < 1 Ω @ f = 10 kHz. The device is designed for automotive applications, therefore it is protected against overload, short circuit, and overtemperature conditions. Figure 4 shows the functional block diagram. If the VS voltage is lower than VUV_OFF, the DMOS of the voltage regulator is switched to high impedance. The body diodes of the DMOS might go into conduction when VCC1µC or VCC2 > VS (no reverse protection). 6.2 Internal Voltage Regulator Modes It is possible to turn Vcc1µC via SBC Modes and Vcc2 activity ON or OFF via SPI command or by entering SBC modes. The limiting current for the both regulators is ICC1µC_max/ICC2. 6.3 Internal Voltage Regulator Modes with SBC Mode Depending on the SBC Mode in use, Vcc1µC and Vcc2 can be either ON or OFF by definition, Vcc2 can be also turned ON or OFF, via SPI. Table 3 identifies the possible states of the voltage regulators, based on the various SBC modes.

Under some conditions there is no “previous command”. Table 22 gives the first SPI output data that is sent to the microcontroller when entering SBC Normal Mode, depending on the mode where the SBC was before receiving the first SPI command. .

The Read Only access clears the INT bits that are selected in the Configuration Select (some interrupt bits show a state, and can not be cleared with a SPI read). With this SPI command no write access is done to the SBC, and the mode of the SBC is not changed. The watchdog can also be triggered with a Read Only command. The Read Only command delivers the information requested with the Configuration Select in the same SPI command on the SDO pin. As all other SPI commands deliver the requested information with the next SPI command. Figure 33 shows an example of a Read Only access. The bits are shown with LSB first, on the left side in difference to the register description.

Data Sheet 77 Rev. 1.0, 2009-03-31 TLE8261E Application Information 15.2 Hints for SBC Factory Flash Mode The mode is used during production of the module to flash the µC. The idea is that the µC is not supplied from the SBC but from an external 5V power supply. The reset of the µC that is connected to the RO pin of the SBC can be driven from an external source and the SBC does not give a reset signal. Also no interrupt at the pin INT and no signal on the SPI SDO pin is generated by the SBC. The SPI pins can be driven externally. The mode is reached by applying 5V to the VCC1µC pin and no voltage to the Vs pin. The Vs pin will show a voltage of about 4.5V because of the internal diode from VCC1µC to Vs. The current drawn at Vs must not exceed the maximum rating of Ivs,max = -500mA. The function is designed for ambient temperature. In case the Vs was supplied before going to FF Mode, the voltage on pin Vs must be set below 3 V before applying 5V to VCC1µC (discharging the C) Not supplied Not supplied 5V Vs VBAT C Reset signal VCC1µC IVS Internal supply The current flowing to other devices from Vs should be limited to not exceed the maximum ratings.
