C912ZVML64L0MKHR

Overview

The C912ZVML64L0MKHR 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 with a maximum clock frequency of 50 MHz. The device integrates 64 KB of Flash memory, 8 KB of RAM, and 512 bytes of EEPROM, all equipped with Error Correction Code (ECC). It includes six 15-bit PWM channels, dual 12-bit ADCs, and a dedicated Gate Drive Unit (GDU) capable of driving up to six power MOSFETs. Operating within a voltage range of 3.5 V to 20 V, it supports LIN physical layer communication and functions reliably in ambient temperatures up to 150°C.

Feature Summary

• Integrated Gate Drive Unit (GDU) supporting up to six external power MOSFETs with integrated bootstrap diodes
• Six 15-bit Pulse Width Modulation (PWM) channels featuring dead-time insertion and fault management
• Dual 12-bit Analog-to-Digital Converters (ADCs) with programmable trigger unit synchronization
• Automotive qualified performance with extended operating temperature range up to 150°C

Applications

• Three-phase motor control systems
• Automotive body electronics
• Industrial motor drives
• LIN bus node implementations

Procurement Notes

Verify the specific suffix L0MKHR against official NXP documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 64-LQFP-EP package. Confirm that the 50 MHz bus speed meets system timing requirements. Validate that the 3.5 V to 20 V supply range aligns with the target application's power architecture.

Selection Notes

Select this component when high-temperature operation up to 150°C is required for automotive or industrial environments. Choose this MCU for applications needing integrated gate drive capabilities for three-phase motors without external drivers. Consider this part if LIN bus connectivity is necessary alongside robust motor control peripherals like 15-bit PWMs and synchronized ADCs.

Part Context

This device belongs to the S12ZVM series of mixed-signal microcontrollers, which are optimized for motor control. It shares architectural similarities with other S12ZVM variants but is distinguished by its 64 KB Flash capacity and specific peripheral integration. The series emphasizes safety features through ECC on memory and SafeAssure program support for functional safety standards.

Replacement Considerations

Consult NXP datasheets for pin-compatible alternatives within the S12ZVM family, such as C912ZVML32 or C912ZVML128, depending on memory requirements. Verify that any substitute maintains the 150°C operating temperature rating and GDU functionality.
