Product details
Overview
S912ZVCA64F0WKH from NXP (formerly Freescale) is an AEC-Q100 Grade 0 automotive MCU integrating a 32 MHz S12Z core, 64 KB Flash, 4 KB RAM, 1-channel MSCAN transceiver, and high-voltage analog peripherals - designed for CAN-based actuators and sensors operating up to 150°C ambient temperature in engine bay or transmission control modules.
For engineers reviewing the S912ZVCA64F0WKH datasheet, S912ZVCA64F0WKH pinout, S912ZVCA64F0WKH application, or S912ZVCA64F0WKH equivalent, key selection criteria include its integrated 12 V CAN PHY, 12-bit ADC with 10 channels, 8-bit DAC with rail-to-rail op-amp, dual high-voltage inputs (HVI), and 4-channel 5 V/25 mA sink GPIO - all in a 64-LQFP-EP package rated for -40°C to +150°C.
Technical Context
The S912ZVCA64F0WKH implements a legacy S12Z CPU core with 32 MHz bus speed and on-chip PLL for clock generation, supporting deterministic real-time control in safety-critical automotive nodes. It integrates dedicated hardware blocks including 8×16-bit timers with 16 ns resolution, 4×16-bit PWM channels, and SENT-Tx for sensor signal conditioning.
Analog subsystem includes two rail-to-rail comparators, a 12-bit ADC (10 input channels), an 8-bit DAC with integrated op-amp, and voltage monitoring via VSUP sense and internal temperature sensor - all powered from a single 5.5–18 V supply without external regulators.

FAQ
What is the maximum ambient operating temperature for the S912ZVCA64F0WKH?
The S912ZVCA64F0WKH is AEC-Q100 Grade 0 qualified with a maximum ambient operating temperature of +150°C. This rating is verified per test condition TA, not junction temperature, and applies across the full voltage range (5.5–18 V). The S912ZVCA64F0WKH maintains functional integrity in engine bay or exhaust aftertreatment locations where airflow and thermal mass limit cooling - unlike lower-grade variants such as S912ZVCA19F0MLF (125°C).
Does the S912ZVCA64F0WKH include an integrated CAN transceiver?
Yes, the S912ZVCA64F0WKH integrates a fully compliant high-speed CAN physical layer (PHY) alongside the MSCAN controller. This eliminates the need for an external CAN transceiver IC, reducing bill-of-materials count and PCB area. The S912ZVCA64F0WKH supports standard CAN 2.0B protocol at up to 1 Mbps and includes built-in ESD protection rated to ±8 kV per HBM - matching requirements for automotive network nodes.
What analog peripherals are included in the S912ZVCA64F0WKH?
The S912ZVCA64F0WKH includes a 10-channel 12-bit ADC, two rail-to-rail comparators, an 8-bit DAC with integrated operational amplifier, and a temperature sensor. These peripherals operate directly from the main 5.5–18 V supply, enabling direct interfacing with automotive sensors such as NOx, humidity, or ultrasonic transducers without external signal conditioning. The S912ZVCA64F0WKH's op-amp supports unity-gain stable configurations for sensor buffering and filtering.
Is the S912ZVCA64F0WKH pin-compatible with other S12ZVC family members?
No, the S912ZVCA64F0WKH is not pin-compatible with 48-pin variants like S912ZVCA19F0MLF due to differing package size and I/O allocation. While it shares the same 64-LQFP-EP footprint as S912ZVCA19F0MKH and S912ZVCA19F0WKH, pin functions differ across flash/RAM configurations - especially for ADC channel mapping and HVI assignments. Board design must reference the S912ZVCA64F0WKH-specific pinout table, not generic S12ZVC documentation.
What development tools support the S912ZVCA64F0WKH?
The S912ZVCA64F0WKH is supported by NXP's legacy CodeWarrior Development Studio and Cosmic compiler toolchain. Hardware evaluation is enabled via the VLG-MC9S12ZVC evaluation board, which provides breakout access to all S912ZVCA64F0WKH signals including CANH/CANL, HVI, NGPIO, and SENT-Tx. Free low-level drivers and peripheral initialization code are available from NXP's MagniV S12ZVC software package - compatible with enterprise third-party tools like Vector CANoe for validation.
