FAQ
What is the maximum ambient temperature rating for the S912ZVCA19F0VLF?
The S912ZVCA19F0VLF is AEC-Q100 Grade 0 qualified with a maximum ambient operating temperature of 150°C. This rating is verified per test condition Tc = 150°C and applies to continuous operation in under-hood or seat-integrated environments. The S912ZVCA19F0VLF internal temperature sensor and thermal shutdown circuitry provide real-time protection at this limit.
Does the S912ZVCA19F0VLF require an external CAN transceiver?
No, the S912ZVCA19F0VLF integrates a fully compliant ISO 11898-2/3 CAN physical layer (PHY) with internal termination and bus fault protection. CANH and CANL pins connect directly to the CAN bus without external components. This integration reduces BOM cost and improves EMC robustness compared to discrete transceiver solutions.
What power supply configurations does the S912ZVCA19F0VLF support?
The S912ZVCA19F0VLF operates directly from a 5.5–18 V battery rail via its VSUP pin. It includes an integrated 12 V / 70 mA regulator (170 mA with ballast) for powering external sensors or logic, plus separate 3.3 V core supply (VDD) and 5 V I/O supply (EVDD). No external DC-DC or LDO is required for basic operation.
How many high-voltage input pins does the S912ZVCA19F0VLF have, and what is their voltage tolerance?
The S912ZVCA19F0VLF features two dedicated high-voltage input (HVI) pins rated for 5.5–18 V operation. These pins tolerate direct connection to 12 V battery rails and are designed for switch sensing, sensor biasing, or wake-up detection without external resistive dividers or level shifters.
Is the S912ZVCA19F0VLF supported by modern development tools?
Yes, the S912ZVCA19F0VLF is supported by NXP's S32DS IDE (with S12Z plugin), legacy CodeWarrior Development Studio, and third-party tools including Cosmic C compiler and low-level drivers for CAN, ADC, and SENT. NXP provides reference designs such as VLG-MC9S12ZVC evaluation board and application notes for ultrasonic and NOx sensor implementations.
