C912ZVML31L0MKFR

Overview

The C912ZVML31L0MKFR is a 16-bit microcontroller from the NXP MagniV S12ZVM family, designed for automotive and industrial motor control applications. It features an enhanced S12Z core with a maximum clock frequency of up to 100 MHz. The device integrates 32 kB of Flash memory, 4 kB of RAM, and 128 B of EEPROM, all equipped with Error Correction Code (ECC). It includes dual 12-bit ADCs, six 15-bit PWM channels, and integrated gate drive circuits. Operating within a voltage range of 3.5 V to 20 V, it supports temperatures from -40°C to +150°C and holds AEC-Q100 qualification.

Feature Summary

• Integrated gate drive unit (GDU) supporting up to three high-side and three low-side power MOSFETs with integrated bootstrap diodes.
• Dual 12-bit analog-to-digital converters (ADCs) with programmable trigger units for synchronized conversion.
• Six 15-bit pulse-width modulation (PWM) channels featuring dead-time insertion and fault management capabilities.
• Two operational amplifiers dedicated to current sensing and measurement functions.

Applications

• Automotive electric power steering systems
• Electric water pump controllers
• Thermal management fan motors
• Industrial servo drives

Procurement Notes

Verify the specific suffix L0MKFR against official NXP documentation to confirm package type, temperature grade, and mass production status. Ensure compatibility with existing PCB footprints for the LQFP-64 EP package. Confirm that the 3.5 V to 20 V operating voltage aligns with the target system's power supply architecture before finalizing procurement.

Selection Notes

Select this component when designing motor control systems requiring integrated power stage drivers and high-temperature operation up to 150°C. The inclusion of LIN physical layer support distinguishes it from non-LIN variants in the same family. Consider the 100 MHz processing speed and ECC protection for applications demanding robust real-time performance and functional safety compliance.

Part Context

This part belongs to the S12ZVM mixed-signal MCU series, which combines a 16-bit processor with analog peripherals and power drivers. It is engineered specifically for cost-sensitive automotive applications where integration reduces bill-of-materials count. The MagniV brand denotes its focus on motor control efficiency and reliability within the broader NXP portfolio.

Replacement Considerations

Cross-reference with other S12ZVML31 variants such as S912ZVML31F1MKHR or S912ZVML31F1WKH. Verify differences in qualification grades (Commercial vs. Automotive) and maximum operating temperatures (-40°C/+125°C vs. -40°C/+150°C) to ensure functional equivalence in the target environment.
