S12Z core with integrated LIN physical layer
The NXP S912ZVMAL3F0MLF is a 16-bit MCU from the S12 MagniV family, built around the S12Z core running at 32 MHz. It packs 32 KB of Flash program memory, 2K x 8 of RAM, and 128 x 8 of EEPROM — enough for local control logic and calibration storage in a LIN-node or small motor-drive application. The wide supply range from 3.5 V to 20 V (Vcc/Vdd) allows direct connection to a 12 V automotive battery without an external regulator, which saves board space and BOM cost in under-hood or engine-bay modules.
Peripherals and connectivity for automotive body control
On-chip peripherals include PWM outputs and a watchdog timer (WDT), plus connectivity via LINbus, SCI, and SPI. The 22 general-purpose I/O lines handle local sensor inputs or actuator drive signals. Seven 10-bit ADC channels bring analog feedback — current sense or potentiometer position — into the digital domain without an external converter. The internal oscillator keeps the BOM lean; no external crystal is required for the core clock.
Package and mounting
Housed in a 48-LQFP package (7x7 mm body), the MCU is surface-mount soldered — standard for automated assembly lines. The supplier device package is 48-LQFP (7x7) as well, so footprint matches the package outline.
Lifecycle and sourcing reality
That means it remains a valid choice for new designs and production builds without an obsolescence clock running. The part is ROHS3 compliant, so it passes EU material restrictions as shipped.
