C912ZVMC64L0WKHR

Overview

The C912ZVMC64L0WKHR is a 16-bit mixed-signal 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 100 MHz and a bus frequency of 50 MHz. The device integrates 64 KB of flash memory with error correction code (ECC), 4 KB of RAM with ECC, and 512 bytes of EEPROM with ECC. It operates within a voltage range of 3.5 V to 20 V and supports an ambient temperature range of -40°C to +150°C. Key peripherals include six 15-bit PWM channels, dual 12-bit ADCs, and dedicated gate drive units.

Procurement Notes

Verify the specific suffix 'H' against official documentation to confirm it denotes the RoHS-compliant variant without halogen content. Ensure the package type matches the required 64-pin HLQFP form factor for your PCB layout. Confirm that the operating temperature grade meets the -40°C to +150°C requirement for your specific environment. Cross-reference the part number with the latest SafeAssure functional safety documentation if used in safety-critical designs.

Selection Notes

Select this component when a robust 16-bit MCU with integrated high-voltage drivers is required. It is suitable for applications needing direct battery connection capabilities up to 20 V. The inclusion of ECC on memory resources makes it ideal for environments demanding high data integrity. Consider this part over standard S12ZVL variants if built-in gate drive functionality reduces external component count.

Part Context

This microcontroller belongs to the S12 MagniV C-series, which is distinct from the L-series by its lack of a LIN physical layer but inclusion of independent voltage regulators and integrated bootstrap diodes. It shares the same core architecture as other C912ZVM devices but offers specific memory configurations. The C-series is tailored for cost-sensitive motor control applications where integrated power stage interfaces are beneficial.

Replacement Considerations

Direct substitutes within the same family include C912ZVMC64L0MKH or C912ZVML64F3WKH, depending on whether LIN PHY support or specific packaging variations are acceptable. Verify pin compatibility and software register mapping before swapping.
