Product details
Overview
S912ZVC64F0MKH from NXP (formerly Freescale) is an AEC-Q100 Grade 0 automotive-qualified S12Z core MCU with integrated CAN transceiver, 64 KB Flash, 4 KB RAM, and 1 KB EEPROM - designed as a system-in-package for space-constrained CAN nodes in HVAC controllers and seat positioning actuators.
For engineers reviewing the S912ZVC64F0MKH datasheet, S912ZVC64F0MKH pinout, S912ZVC64F0MKH application, or S912ZVC64F0MKH equivalent, key selection criteria include its -40°C to 125°C operating range, 64-LQFP-EP package, integrated 12V/70mA voltage regulator, dual rail-to-rail comparators, and 8-channel 16-bit PWM with 16 ns resolution.
Technical Context
The S912ZVC64F0MKH implements a 32 MHz S12Z CPU core with on-chip PLL and internal 12-bit ADC (10–16 channels), 8-bit DAC with integrated op-amp, and dedicated SENT-Tx interface for ultrasonic sensor communication. It supports MSCAN with built-in PHY, eliminating external transceiver requirements.
Its analog subsystem includes two rail-to-rail comparators, four 5V-sink NGPIOs, one 5V-source EVDD channel, and high-voltage inputs (HVI) rated for direct battery connection (5.5 V–18 V). The timer subsystem delivers eight 16-bit timers plus four 16-bit PWM channels, all with 16 ns timing resolution.

The S912ZVC64F0MKH is AEC-Q100 Grade 0 qualified with a maximum ambient operating temperature of +125°C. This rating is validated per JEDEC JESD22-A108 and applies to continuous operation under specified voltage and load conditions. The S912ZVC64F0MKH maintains full functionality and timing specifications across this range without derating.
Does the S912ZVC64F0MKH require an external CAN transceiver?
No, the S912ZVC64F0MKH integrates a fully compliant CAN physical layer (PHY) supporting both high-speed and low-speed CAN protocols. Its CANH and CANL pins connect directly to the CAN bus with only passive termination resistors required. No external transceiver is needed, reducing BOM count and PCB area for single-node applications.
What power supply configuration does the S912ZVC64F0MKH support?
The S912ZVC64F0MKH operates directly from a 5.5 V–18 V supply, with an integrated 12 V/70 mA voltage regulator that powers the core, peripherals, and CAN PHY. It also provides one 5 V/20 mA source (EVDD) and four 5 V/25 mA sink outputs (NGPIO0–3), enabling direct driving of sensors and actuators without external regulators.
How many analog-to-digital converter channels does the S912ZVC64F0MKH include?
The S912ZVC64F0MKH features a 10-channel, 10-bit successive-approximation ADC with configurable sample-and-hold and scan sequencing. Channels support multiplexed inputs from internal sources (temperature sensor, VDD, bandgap) and external pins. Conversion time is 8 µs per channel with hardware-triggered start capability.
Is the S912ZVC64F0MKH pin-compatible with other S12ZVC variants?
Yes, the S912ZVC64F0MKH shares identical pinout and package (64-LQFP-EP) with S912ZVCA19F0MKH and S912ZVCA19F0WKH. Differences are limited to Flash size (64 KB vs. 192 KB), temperature grade (125°C vs. 150°C), and mask ROM content - enabling drop-in replacement in existing layouts where memory or thermal margin permits.
