Overview
The C9S12VR48AL0VLFR is a 16-bit microcontroller from the NXP S12 MagniV family, utilizing the HCS12 core architecture. It features 48KB of Flash program memory and 2KB of RAM. The device operates at a maximum clock frequency of 25MHz and supports an analog supply voltage range of 3.13V to 5.5V. It includes a 10-bit ADC with six channels and offers connectivity via LINbus, SCI, SPI, and IrDA interfaces. Packaged in a 48-LQFP format, it is qualified for automotive applications and functions within a temperature range of -40°C to +105°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments
- Integrated LINbus controller supporting local interconnect network communication protocols
- Built-in hardware security features including flash protection and code readout prevention
Applications
- Body control modules for automotive lighting and window management
- Door control units and keyless entry systems
- Seat adjustment controllers and mirror positioning systems
Procurement Notes
Verify the specific suffix 'L0' against official NXP documentation to confirm pin compatibility and feature set, as ordering codes may indicate package or temperature variations. Ensure the component meets the required AEC-Q100 grade for your target application. Cross-reference the datasheet revision date to validate interface support and electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this model when automotive-grade reliability is required alongside integrated LINbus capabilities. The 48KB Flash size suits moderate complexity control algorithms. Compare against the S9S12 variant if industrial temperature ranges suffice, noting that the C-prefix typically denotes automotive qualification. Verify I/O count requirements against the 48-pin LQFP package limitations.
Part Context
This part belongs to the S12 MagniV series, designed specifically for automotive body electronics. It bridges the gap between high-performance PowerPC solutions and lower-cost 8-bit MCUs. The C9S12VR48AL0VLFR represents the automotive-qualified version of the VR48 family, emphasizing cost-effective integration of connectivity and processing power for chassis and body applications.
Replacement Considerations
The S9S12VR48AF0VLF is a related industrial-grade counterpart within the same family. Verify if automotive qualification is strictly necessary; if not, the S9S12 variant may offer availability advantages. Check pin-to-pin compatibility and software library support before substituting.
