Boost Counter with CBC MAC (Cipher block chaining message authentication code) CMOS Complementary Metal Oxide Semiconductor.
SiP, it supplies the internal power needed trough VSUP and VPRE using the aforementioned 12V supply. This further reduces the bill of materials and saves space. 6.1 S32M276SFFRD – Main Power Supply Figure 3. S32M276SFFRD – Main power supply input Table 2. Main power supply connector Connector...
PCB. The values of the decoupling and bulk capacitors are descripted in the Table 3 Figure 6. S32M276SFFRD – VDD_HV_A power supply 6.3 S32M276SFFRD – VDDC_MCU VDDC is CAN supply pin whose voltage is generated by internal voltage regulator from VPRE which can be enabled or disabled to decrease power consumption, this voltage is typically 5V.

S32M276SFFRD – VDDC_MCU 6.4 S32M276SFFRD – V11 The V11 power pins must be shorted together externally on their voltage domain. Appropriate bulk/bypass and decoupling capacitors should be used to filter noise on the supply. Those pins are the core and logic supply.
S32M276SFFRD HWUM NXP Semiconductors S32M276SFFRD - Hardware User Manual 6.5 S32M276SFFRD – V25 V25 pin supplies the flash memory and (via double bond) the clock modules, this voltage is internally generated from VDD_HV_A. Figure 9. S32M276SFFRD – V25 6.6 S32M276SFFRD – VREFH The Reference Voltage High (VREFH) should be connected to the same voltage as VDD or may be driven by an external source to a level between the minimum VREFH and the VDDA potential (VDDA + 0.1V and VDD + 0.1 V, or VDD_HV_A + 0.1V).
Bulk Capacitor X7R / X8R Ceramic 4.7uF - 2.2uF 7 S32M276SFFRD – Programming and Debug Interface 7.1 S32M276SFFRD – RESET Switch The RESET switch [SW1] provides an input signal for manual RESET. The S32M276 MCU will drive the RESET signal to reset the board peripherals.
7.2 S32M276SFFRD – JTAG The S32M276SFFRD incorporates JTAG connectors to program the MCU using a PE Multilink Universal FX Debug Probe which allows the user control the target’s execution, read/write registers and memory values, debug code on the processor, and program internal or external FLASH memory devices.
NXP Semiconductors S32M276SFFRD - Hardware User Manual 10 S32M276SFFRD – Motor Control Interface Another feature of the S32M276 MCU is the GDU which provides pre-drivers to control three-phase DC motor via external FETs. In order to support this control, it includes a charge pump and boost converter. The above replace a bootstrap circuit for gate driving.
