Guaranteed by design. 3.6.2 3.6.2.1 Dynamic Electrical Characteristics MCU Die NVM Timing The time base for all NVM program or erase operations is derived from the bus block. A minimum bus frequency fNVMBUS is required for performing program or erase operations. The NVM module do not has any means to monitor the frequency and does not prevent a program or erase operation at frequencies above or below the specified minimum. Attempting to program or erase the NVM modules at a lower frequency, a full program, or erase transition is not assured. The Flash program and erase operations are timed using a clock derived from the bus clock using the FCLKDIV and register. The frequency of this clock must be set within the limits specified as fNVMOP. The minimum program and erase times shown in Table 37 are calculated for maximum fNVMOP and maximum fBUS. The maximum times are calculated for minimum fNVMOP and a fBUS of 2.0 MHz. 3.6.2.1.1 Single Word Programming The programming time for single word programming is dependant on the bus frequency as a well as on the frequency fNVMOP, and can be calculated according to the following formula. t 3.6.2.1.2 swpgm 1 1 = 9  ------------------------- + 25  ----------f f NVMOP bus Burst Programming This applies only to the Flash, where up to 64 words in a row can be programmed consecutively, using burst programming by keeping the command pipeline filled. The time to program a consecutive word can be calculated as: bwpgm 1 1 = 4  ------------------------- + 9  ----------f f NVMOP bus t = t t The time to program a whole row is: brpgm swpgm + 63  t bwpgm Burst programming is more than 2 times faster than single word programming. 3.6.2.1.3 Sector Erase NOTE The sector erase cycle is divided into 16 individual erase pulses to achieve faster system response during the erase flow. The given erase time (tERA) specifies the time considering consecutive pulses.

To avoid short-circuit conditions being present for a long time, a tVTO timeout is implemented. Once VDD < VLVR or VDDX < VLVRX with VS1 > (VLVRI+ VLVR _H) for more than tVTO, the MM912F634 analog die transitions directly to Sleep mode.

Both regulators (VDD and VDDX) are active and operate with full current capability. Once entered in Normal mode, the Watchdog operates as a simple non-window watchdog with an initial timeout (tIWDTO) to be reset via the D2D Interface. After the initial reset, the watchdog operates in standard window mode. See Section 4.9, “Window Watchdog" for details. 4.3.4 Stop Mode NOTE To avoid any pending analog die interrupts prevent the MCU from entering MCU stop resulting in unexpected system behavior, the analog die IRQ sources should be disabled and the corresponding flags be cleared before entering stop. The Stop mode allows reduced current consumption with fast startup time. In this mode, both voltage regulators (VDD and VDDX) are active, with limited current drive capability. In this condition, the MCU is supposed to operate in Low Power mode (STOP or WAIT). The device can enter in Stop mode by configuring the Mode Control Register (MCR) via the D2D Interface. The MCU has to enter a Low Power mode immediately afterwards executing the STOP or WAIT instruction. The Wake-up Source Register (WSR) has to be read after a wake-up condition in order to execute a new STOP mode command. Two base clock cycles (fBASE) delay are required between WSR read and MCR write. While in Stop mode, the MM912F634 analog die wakes up on the following sources: • • • • Lx - Wake-up (maskable with selectable cyclic sense) Forced Wake-up (configurable timeout) LIN Wake-up D2D Wake-up (special command) After Wake-up from the sources listed above, the device transitions to Normal mode. Reset wakes up the device directly to Reset mode. See Section 4.8, “Wake-up / Cyclic Sense" for details. 4.3.5 Sleep Mode The Sleep mode allows very low current consumption. In this mode, both voltage regulators (VDD and VDDX) are inactive. The device can enter into Sleep mode by configuring the Mode Control Register (MCR) via the D2D- Interface. During Sleep mode, all unused internal blocks are deactivated to allow the lowest possible consumption. Power consumption decreases further if the Cyclic Sense or Forced Wake-up feature are disabled. While in Sleep mode, the MM912F634 analog die wakes up on the following sources: • Lx - Wake-up (maskable with selectable cyclic sense) • Forced Wake-up (configurable timeout) • LIN Wake-up After Wake-up from the sources listed above or a reset condition, the device transitions to Reset mode.

MM912F634 Analog Integrated Circuit Device Data Freescale Semiconductor 53 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 4.4 Power Supply The MM912F634 analog die supplies VDD (2.5 V), VDDX (5.0 V), and HSUP, based on the supply voltage applied to the VS1 pin. VDD is cascaded of the VDDX regulator. To separate the High-side outputs from the main power supply, the VS2 pin does only power the High-side drivers. Both supply pins have to be externally protected against reverse battery conditions. To supply external Hall Effect Sensors, the HSUP pin supplies a switchable regulated supply. See Section 4.10, “Hall Sensor Supply Output - HSUP". A reverse battery protected input (VSENSE) is implemented to measure the Battery Voltage directly. A serial resistor (RVSENSE) is required on this pin. See Section 4.22, “Supply Voltage Sense - VSENSE". In addition, the VS1 supply can be routed to the ADC (VS1SENSE) to measure the VS1 pin voltage directly. See Section 4.23, “Internal Supply Voltage Sense - VS1SENSE". To have an independent ADC verification, the internal sleep mode bandgap voltage can be routed to the ADC (BANDGAP). As this node is independent from the ADC reference, any out of range result would indicate malfunctioning ADC or Bandgap reference. See Section 4.24, “Internal Bandgap Reference Voltage Sense - BANDGAP". To stabilize the internal ADC reference voltage for higher precision measurements, the current limited ADC2p5 pin needs to be connected to an external filter capacitor (CADC2p5). It is not recommended to connect additional loads to this pin. See Section 4.19, “Analog Digital Converter - ADC". The following safety features are implemented: VSENSE VS1 LBI - Low Battery Interrupt, internally measured at VSENSE LVI - Low Voltage Interrupt, internally measured at VS1 HVI - High Voltage Interrupt, internally measured at VS2 VROVI - Voltage Regulator Overvoltage Interrupt internally measured at VDD and VDDX LVR - Low Voltage Reset, internally measured at VDD LVRX - Low Voltage Reset, internally measured at VDDX HTI - High Temperature Interrupt measured between the VDD and VDDX regulators Overtemperature Shutdown measured between the VDD and VDDX regulators VS2 • • • • • • • • LBI HVI HS1 HS2 ÷ HS1 & HS2 LVI ADC bg1p25sleep HSUP HSUP (18V) Regulator VDDX (5V) Regulator CHSUP VDDXINTERNAL VDDX LVRX VROV CVDDX ADC2p5 ADC 2.5V Reference VDD (2.5V) Regulator CADC VDD VDDINTERNAL LVR CVDD Figure 17.

External capacitors (CVDD) and (CVDDX) are required for proper regulation. 4.4.2 Power Up Behavior / Power Down Behavior To guarantee safe power up and down behavior, special dependencies are implemented to prevent unwanted MCU execution. Figure 18 shows a standard power up and power down sequence. MCU_POR MCU_POR RESET_A Normal Operating Range (not to scale) VLBI / VLVI VROVX 5V VLVRX VROX VLVR 4 1 5 2 VPOR_A VPOR_MCU 3 VSUP 6 VDDX VDD Figure 18. Power-up / Down Sequence To avoid any abnormal device behavior, it is essential to have the MCU Power on Reset (POR) block complete its start-up sequence before the analog die reset signal (RESET A) is asserted. Since the RESET A circuitry is supplied by VDDX, the voltage on the 2.5 V supply (VDD) needs to remain below the POR threshold whenever VDDX is too low to guarantee RESET A can be properly asserted (3;6). This is achieved with the following implementation. Power-up: • The VDD regulator is enabled after VDDX has reached the VLVRX threshold (1). • Once VDD reaches VLVR, the RESET_A is released (2). Power-down: • Once VDDX has reached the VLVRX threshold (4), the VDD regulator is disabled and the regulator output is actively pulled down to discharge any VDD capacitance (5). RESET_A is activated as well. • The active discharge guarantees VDD to be below POR level before VDDX discharges below critical level for the reset circuity.

Access to the MM912F634 analog die is controlled by the D2D Interface module. This section describes the functionality of the die-to-die target block (D2D). 4.5.1 Overview The D2D is the target for a data transfer from the target to the initiator (MCU). The initiator provides a set of configuration registers and two memory mapped 256 Byte address windows. When writing to a window, a transaction is initiated sending a write command, followed by an 8-bit address, and the data byte or word is received from the initiator. When reading from a window, a transaction is received with the read command, followed by an 8-bit address. The target then responds with the data. The basic idea is that a peripheral located on the MM912F634 analog die, can be addressed like an on-chip peripheral. Features: • • • • • • • software transparent register access to peripherals on the MM912F634 analog die 256 Byte address window supports blocking read or write, as well as non-blocking write transactions 4 bit physical bus width automatic synchronization of the target when initiator starts driving the interface clock generates transaction and error status as well as EOT acknowledge providing single interrupt interface to D2D Initiator MM912F634 Analog Integrated Circuit Device Data Freescale Semiconductor 57 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 4.5.2 Low Power Mode Operation The D2D module is disabled in SLEEP mode. In Stop mode, the D2DINT signal is used to wake-up a powered down MCU. As the MCU could wake up without the MM912F634 analog die, a special command is recognized as a wake-up event during Stop mode. See Section 4.3, “Modes of Operation". 4.5.2.1 Normal Mode / Stop Mode NOTE The maximum allowed clock speed of the interface is limited to fD2D. While in Normal or Stop mode, D2DCLK acts as input only with pull present. D2D[3:0] operates as an input/output with pull-down always present. D2DINT acts as output only. 4.5.2.2 Sleep Mode While in Sleep mode, all Interface data pins are pulled down to DGND to reduce power consumption. 4.6 Interrupts Interrupts are used to signal a microcontroller that a peripheral needs to be serviced. While in Stop mode, the interrupt signal is used to signal Wake-up events. The interrupts are signaled by an active high level of the D2DINT pin, which remains high until the interrupt is acknowledged via the D2D-Interface. Interrupts are only asserted while in Normal mode. 4.6.1 Interrupt Source Identification Once an Interrupt is signalized, there are two options to identify the corresponding source(s). 4.6.1.1 Interrupt Source Mirror NOTE The VSI - Voltage Status Interrupt combines the five status flags for the Low Battery Interrupt, Low Voltage Interrupt, High Voltage Interrupt, Voltage Regulator Overvoltage Interrupt, and the Voltage Regulator High Temperature Interrupt. The specific source can be identified by reading the Voltage Status Register - VSR. All Interrupt sources in MM912F634 analog die are mirrored to a special Interrupt Source Register (ISR). This register is read only and indicates all currently pending Interrupts. Reading this register does not acknowledge any interrupt. An additional D2D access is necessary to serve the specific module. 4.6.1.1.1 Interrupt Source Register (ISR) Table 78.

To allow an offset based vector table, the result is pre-shifted (multiple of 2). Reading this register does not acknowledge an interrupt.

MM912F634 Analog Integrated Circuit Device Data Freescale Semiconductor 61 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 4.7 Resets To protect the system during critical events, the MM912F634 analog die drives the RESET_A pin low during the presence of the reset condition. In addition, the RESET_A pin is monitored for external reset events. To match the MCU, the RESET_A pin is based on the VDDX voltage level. After an internal reset condition has gone, the RESET_A stays low for an additional time tRST before being released. Entering reset mode causes all MM912F634 analog die registers to be initialized to their RESET default. The only registers with valid information are the Reset Status Register (RSR) and the Wake-up Source Register (WUS). 4.7.1 Reset Sources In the MM912F634 six reset sources exist. 4.7.1.1 POR - Analog Die Power On Reset To indicate the device power supply (VS1) was below VPOR or the MM912F634 analog die was powered up, the POR condition is set. See Section 4.3, “Modes of Operation". 4.7.1.2 LVR - Low Voltage Reset - VDD With the VDD voltage regulator output voltage falling below VLVR, the Low Voltage Reset condition becomes present. As the VDD Regulator is shutdown once a LVRX condition is detected, The actual cause could be also a low voltage condition at the VDDX regulator. See Section 4.4, “Power Supply". 4.7.1.3 LVRX - Low Voltage Reset - VDDX With the VDDX voltage regulator output voltage falling below VLVRX, the Low Voltage Reset condition becomes present. See Section 4.4, “Power Supply". 4.7.1.4 WUR - Wake-up Reset While in Sleep mode, any active wake-up event causes a MM912F634 analog die transition from Sleep to Reset Mode. To determine the wake-up source, refer to Section 4.8, “Wake-up / Cyclic Sense". 4.7.1.5 EXR - External Reset Any low level voltage at the RESET_A pin with a duration > tRSTDF issues an External Reset event. This reset source is also active in Stop mode. 4.7.1.6 WDR - Watchdog Reset Any incorrect serving if the MM912F634 analog die Watchdog results in a Watchdog Reset. Refer to the Section 4.9, “Window Watchdog" for details. 4.7.2 Register Definition 4.7.2.1 Reset Status Register (RSR) Table 83.

Reading the Reset Status register clears the information inside. Writing has no effect. LVR and LVRX are masked when POR or WUR are set. 4.8 Wake-up / Cyclic Sense To wake-up the MM912F634 analog die from Stop or Sleep mode, several wake-up sources are implemented. As described in Section 4.3, “Modes of Operation", a wake-up from Stop mode results in an interrupt (D2DINT) to the MCU combined with a transition to Normal mode. A wake-up from Sleep mode results in a transition to Reset mode. In any case, the source of the wake-up can be identified by reading the Wake-up Source Register (WSR). The Wake-up Source Register (WSR) has to be read after a wake-up condition in order to execute a new STOP mode command. Two base clock cycles (fBASE) delay are required between the WSR read and MCR write. In general, there are the following seven main wake-up sources: • • • • • • • Wake-up by a state change of one of the Lx inputs Wake-up by a state change of one of the Lx inputs during a cyclic sense Wake-up due to a forced wake-up Wake-up by the LIN module Wake-up by D2D interface (Stop mode only) Wake-up due to internal / external Reset (Stop mode only) Wake-up due to loss of supply voltage (Sleep mode only) VSUP HS1 HS2 D2DINT Wake Up Module D2DCLK D2D3 D2D2 Forced Wake Up Cyclic Sense / Forced Wake Up Timer D2D Wake Up L0 L1 L2 D2D1 L3 D2D0 Cyclic Wake Up Lx – Wake Up LIN Wake Up L4 L5 LIN LIN Bus Figure 19. Wake-up Sources MM912F634 Analog Integrated Circuit Device Data Freescale Semiconductor 63 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 4.8.1 4.8.1.1 Wake-up Sources Lx - Wake-up (Cyclic Sense Disabled) Any state digital change on a Wake-up Enabled Lx input issues a wake-up. In order to select and activate a Wake-up Input (Lx), the Wake-up Control Register (WCR) must be configured with appropriate LxWE inputs enabled or disabled before entering low power mode. The Lx - Wake-up may be combined with the Forced Wake-up. Note: Selecting a Lx Input for wake-up disables a selected analog input once entering low power mode. 4.8.1.2 Lx - Cyclic Sense Wake-up NOTE Once Cyclic Sense is configured (CSSEL!=0), the state change is only recognized from one cyclic sense event to the next. The additional accuracy of the cyclic sense cycle by the WD clock trimming is only active during STOP mode. There is no trimmed clock available during SLEEP mode. To reduce external power consumption during low power mode a cyclic wake-up has been implemented. Configuring the Timing Control Register (TCR) a specific cycle time can be selected to implement a periodic switching of the HS1 or HS2 output with the corresponding detection of an Lx state change. Any configuration of the HSx in the High-side Control Register (HSCR) is ignored when entering low power mode. The Lx - Cyclic Sense Wake-up may be combined with the Forced Wake-up. In case both (forced and Lx change) events are present at the same time, the Forced Wake-up is indicated as Wake-up source. 4.8.1.3 Forced Wake-up Configuring the Forced Wake-up Multiplier (FWM) in the Timing Control Register (TCR) enables the forced wake-up based on the selected Cyclic Sense Timing (CST). Forced Wake-up can be combined with all other wake-up sources considering the timing dependencies. 4.8.1.4 LIN - Wake-up While in Low-Power mode the MM912F634 analog die monitors the activity on the LIN bus. A dominant pulse longer than tPROPWL followed by a dominant to recessive transition causes a LIN Wake-up. This behavior protects the system from a short-to-ground bus condition. 4.8.1.5 D2D - Wake-up (Stop Mode Only) Receiving a Normal mode request via the D2D interface (MODE=0, Mode Control Register (MCR)) results in a wake-up from stop mode. As this condition is controlled by the MCU, no wake-up status bit does indicate this wake-up source. 4.8.1.6 Wake-up Due to Internal / External Reset (STOP Mode Only) While in Stop mode, a Reset due to a VDD low voltage condition or an external Reset applied on the RESET_A pin results in a Wake-up with immediate transition to Reset mode. In this case, the LVR or EXR bits in the Reset Status Register indicates the source of the event. 4.8.1.7 Wake-up Due to Loss of Supply Voltage (SLEEP Mode Only) While in Sleep mode, a supply voltage VS1 < VPOR results in a transition to Power On mode.

TCR - Register Field Descriptions Field Description 7-4 FWM Forced Wake-up Multiplicator - Configures the multiplicator for the forced wake-up. The selected multiplicator (FWM!=0) forces a wake-up every FWM x CST ms. With this implementation, Forced and Cyclic wake-up can be performed in parallel with the cyclic sense period
