C912ZVML12L0WKHR

Overview

The C912ZVML12L0WKHR is a 16-bit microcontroller from the NXP S12 MagniV family, utilizing the enhanced S12Z core. It features 128 kB of Flash memory with ECC and 8 kB of RAM with ECC. The device operates within a voltage range of 3.5 V to 20 V and supports clock frequencies up to 100 MHz. It integrates six 15-bit PWM channels for motor control, dual 12-bit ADCs, and a dedicated gate drive unit (GDU) capable of driving three high-side and three low-side power MOSFETs. Connectivity includes LIN physical layer support, MSCAN, SCI, SPI, and I2C interfaces.

Feature Summary

• Integrated gate drive unit (GDU) for direct control of three high-side and three low-side power MOSFETs
• Six 15-bit PWM channels with hardware dead-time insertion and fault management for motor applications
• LIN physical layer integration supporting local interconnect network communication protocols
• Dual 12-bit analog-to-digital converters with programmable trigger unit for synchronized sampling

Applications

• Automotive body electronics and lighting control modules
• Electric power steering systems
• Thermal management and cooling fan controllers
• Window lift and seat adjustment actuators

Procurement Notes

Verify the specific suffix 'WKHR' against official NXP documentation to confirm package type, temperature grade, and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the LQFP-64-EP package. Confirm that the LIN PHY functionality aligns with system requirements, as this feature is specific to the L-series variants within the C912ZVM family.

Selection Notes

Select this component when a mixed-signal MCU with integrated power stage drivers is required for automotive applications. The inclusion of the LIN PHY distinguishes it from standard C-series variants. Evaluate the 128 kB Flash capacity against application code size needs. Consider the 20 V operating voltage limit for systems powered directly by vehicle battery lines without additional regulation.

Part Context

This part belongs to the S12 MagniV C912ZVM series, designed for mixed-signal automotive control. It combines a high-performance 16-bit CPU with analog peripherals and power drivers. The 'L' designation indicates the presence of a LIN physical layer, while the '12' denotes the 128 kB Flash memory configuration. It serves as an alternative to discrete driver solutions in compact motor control designs.

Replacement Considerations

Direct substitutes include other members of the S12ZVM family such as the C912ZVML64 or C912ZVML32, depending on memory requirements. Cross-reference pinouts and electrical characteristics carefully, as variations exist between L-series and C-series packages.
