C912ZVML64L0WKH

Overview

The C912ZVML64L0WKH is a 16-bit microcontroller from the NXP S12 MagniV family, designed for automotive and industrial motor control applications. It features an enhanced S12Z core operating at up to 50 MHz bus frequency with 64 KB of Flash memory. The device includes 4 KB of RAM, 512 bytes of EEPROM, and six channels of 15-bit PWM output. Integrated peripherals include LIN physical layer, two operational amplifiers for current sensing, dual 12-bit ADCs, and a Gate Drive Unit (GDU) supporting up to three high-side and three low-side power MOSFETs.

Feature Summary

• Integrated LIN physical layer for robust automotive communication
• Six-channel 15-bit PWM generation with dead-time and fault management
• Built-in gate drive unit for direct control of external power MOSFETs
• Dual 12-bit analog-to-digital converters with programmable trigger unit

Applications

• Automotive electric power steering systems
• Industrial motor control drives
• Active suspension systems
• Thermal management pumps and fans

Procurement Notes

Verify the specific suffix L0WKH against official NXP documentation to confirm package type, temperature range, and mass production status. Ensure compatibility with existing PCB footprints and thermal requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a mixed-signal MCU with integrated gate drivers and LIN interface is required. Compare storage capacities and pin counts within the S12ZVM family if different I/O or memory configurations are needed. Evaluate the GDU capabilities against the target power stage requirements.

Part Context

This part belongs to the S12 MagniV series, which targets cost-sensitive motor control applications. The C912ZVML64 variant specifically offers a balance of processing power and integrated power stage interfaces. It is distinct from the S912 series by its automotive qualification and extended temperature ranges.

Replacement Considerations

Check for functional equivalents within the S12ZVM family such as C912ZVML32 or C912ZVML128 depending on memory needs. Verify pin-to-pin compatibility with previous design iterations.
