C912ZVML32L0WKH

Overview

The C912ZVML32L0WKH is a 16-bit mixed-signal microcontroller from the MagniV S12ZVM family, designed for automotive and industrial motor control applications. It features an enhanced S12Z core with a maximum clock frequency of 100 MHz and a bus frequency of 50 MHz. The device integrates 32 kB of Flash memory with ECC, 4 kB of RAM with ECC, and 128 B of EEPROM with ECC. It includes six 15-bit PWM channels for motor control, dual 12-bit ADCs, and a Programmable Trigger Unit (PTU). The MCU operates within a voltage range of 3.5 V to 20 V and supports a LIN physical layer. It is qualified for automotive use and rated for an ambient temperature range of -40°C to +150°C.

Feature Summary

• Enhanced S12Z kernel supporting up to 100 MHz clock frequency
• Integrated 6-channel 15-bit PWM with dead-time insertion and fault management
• Dual 12-bit ADCs with programmable trigger unit for synchronous conversion
• Built-in LIN physical layer transceiver for automotive communication

Applications

• Automotive motor control systems
• Industrial motor drives
• LIN node implementations in vehicles
• Sensor interfaces and actuators requiring high-temperature operation

Procurement Notes

Verify the specific suffix L0WKH against official NXP documentation to confirm package type, temperature grade, and mass production status. Ensure compatibility with existing design tools and software development kits provided by NXP for the S12ZVM family. Confirm that the automotive qualification meets the specific safety requirements of your target application before finalizing procurement.

Selection Notes

Select this component when a 16-bit architecture with integrated power gate drivers and analog peripherals is required for motor control. The S12ZVML variant specifically offers a built-in LIN transceiver, distinguishing it from non-LIN versions. Consider the 32 kB Flash capacity for code size requirements and the -40°C to +150°C operating range for harsh environment deployment. Evaluate the need for ECC protection on memory resources for functional safety compliance.

Part Context

This part belongs to the MagniV S12ZVM mixed-signal MCU series, which targets cost-sensitive automotive and industrial applications. The family provides scalability across different memory sizes and peripheral sets while maintaining a common core architecture. The S12ZVML sub-series is optimized for LIN-based networks, integrating the necessary physical layer components directly on-chip to reduce external component count and board space.

Replacement Considerations

Check NXP's official cross-reference lists for direct pin-to-pin replacements within the S12ZVM family. Variants such as C912ZVML64L0MKH offer higher memory but may require software adaptation. Ensure any substitute maintains the same package footprint and thermal characteristics.
