C912ZVML31L0WKF

Overview

The C912ZVML31L0WKF is a 16-bit microcontroller from the NXP MagniV S12ZVM family, designed for automotive applications. It features an enhanced S12Z core with a maximum clock frequency of 50 MHz. The device includes 32 kB of Flash memory, 4 kB of RAM, and 128 B of EEPROM, all equipped with Error Correction Code (ECC). It operates within a temperature range of -40°C to +150°C and is housed in a 64-pin LQFP-EP package. Key peripherals include dual 12-bit ADCs, a Programmable Trigger Unit (PTU), and six PWM channels.

Feature Summary

• Integrated LIN physical layer for local interconnect network communication
• Gate Drive Unit (GDU) capable of driving up to six external power MOSFETs
• Dual 12-bit Analog-to-Digital Converters (ADC) with synchronous conversion capabilities via PTU
• Built-in Error Correction Code (ECC) for Flash, RAM, and EEPROM

Applications

• Three-phase sensorless BLDC motor control for fuel pumps, water pumps, and oil pumps
• HVAC blower and engine cooling fan drive systems
• Automotive air conditioning compressor control
• Brushed DC motor control for reversible wipers and tailgates

Procurement Notes

Verify the specific suffix 'L0WKF' against official NXP documentation to confirm pinout compatibility and feature set variations. Ensure the component meets AEC-Q100 qualification requirements for the target automotive environment. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this model when high-temperature operation up to 150°C is required alongside integrated gate drive capabilities. The inclusion of the LIN physical layer makes it suitable for cost-sensitive body electronics and motor control applications where direct LIN bus connectivity is necessary without external transceivers.

Part Context

This part belongs to the S12ZVML sub-series of the MagniV family, which specifically integrates the LIN physical layer. It shares the same 64-pin LQFP-EP footprint as other variants like the S912ZVML31F1WKH but may differ in internal memory configurations or qualification grades. It is optimized for single-chip solutions in motor drives.

Replacement Considerations

Direct substitutes include S912ZVML31F1WKH and S912ZVML31F1MKH. Verify that the replacement variant matches the required operating temperature range and voltage specifications.
