Product details
Overview
S912ZVC12F0VLF from NXP (formerly Freescale) is an AEC-Q100 Grade 0 automotive-qualified 32 MHz S12Z core MCU with integrated CAN transceiver, 12-bit ADC (10–16 channels), 8-bit DAC with op-amp, and 12 V/70 mA voltage regulator - designed for space-constrained CAN nodes in seatbelt pretensioners, ultrasonic sensors, and NOx powertrain sensors.
For engineers reviewing the S912ZVC12F0VLF datasheet, S912ZVC12F0VLF pinout, S912ZVC12F0VLF application, or S912ZVC12F0VLF equivalent, key selection factors include its integrated 12 V CAN PHY, 150°C ambient operation, dual high-voltage inputs (HVI), SENT-Tx interface, and battery-direct operation without external LDO or transceiver.
Technical Context
The S912ZVC12F0VLF implements a 32 MHz S12Z CPU core with on-chip PLL and internal RC oscillator, supporting deterministic real-time control in safety-critical automotive subsystems. It integrates a single MSCAN controller with embedded physical layer compliant to ISO 11898-2/3, eliminating external CAN transceiver components.
Analog subsystem includes two rail-to-rail comparators, four 5 V sink GPIOs (NGPIO), one 5 V source EVDD output, and a dedicated VSUP sense input for battery monitoring. The 12-bit ADC supports up to 16 channels with configurable sample timing and hardware trigger synchronization to PWM or timer events.
