Overview
The C9S12VR48AL0VLF 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, operating at a maximum clock frequency of 25MHz. The device includes 512 bytes of EEPROM data storage and supports an input voltage range of 3.13V to 5.5V. It offers 28 I/O pins and integrates peripherals such as LINbus, SCI, SPI, IrDA, PWM, WDT, LVD, and POR. The unit is housed in a 48-LQFP package and is qualified for automotive applications with an operating temperature range of -40°C to +105°C.
Feature Summary
- Automotive-qualified 16-bit MCU based on the S12 core architecture
- Integrated connectivity interfaces including LINbus, SCI, SPI, and IrDA
- Built-in peripheral protection features such as Low Voltage Detection (LVD) and Power-On Reset (POR)
- Supports pulse-width modulation (PWM) and watchdog timer (WDT) functions
Applications
- Automotive body electronics control modules
- Local Interconnect Network (LIN) slave nodes
- Sensor interface units requiring serial communication
- General-purpose embedded control systems in harsh environments
Procurement Notes
Verify the specific suffix 'L0' against the official NXP datasheet to confirm pinout compatibility and electrical characteristics relative to other variants in the S9S12VR series. Ensure that the 48-LQFP package dimensions match the target PCB footprint. Confirm that the component meets the required AEC-Q100 reliability standards for the intended automotive application environment before finalizing procurement specifications.
Selection Notes
Select this component when a robust 16-bit architecture with integrated LIN capability is required for cost-sensitive automotive applications. The 48KB Flash size provides sufficient code space for moderate complexity control algorithms. Consider the 25MHz speed limit and 28 available I/O lines to ensure they meet the system's processing and connectivity demands without unnecessary resource overhead.
Part Context
This part belongs to the S12 MagniV family, designed specifically for automotive body and chassis applications. It complements higher-performance MCUs by offering a balance of processing power, connectivity, and cost efficiency. The family emphasizes reliability and integration of common automotive protocols, reducing external component count and simplifying system design for manufacturers.
Replacement Considerations
Check for direct substitutes within the S9S12VR series, such as S9S12VR48AF0VLC or S9S12VR48AF0VLF, verifying package and pin compatibility. Cross-reference with the MC9S12VR family reference manual for functional equivalence. Ensure any replacement maintains the same automotive qualification level and thermal performance ratings.
