FAQ

What is the maximum operating frequency of the S9S12G48F1CLC?

The S9S12G48F1CLC supports a maximum core clock frequency of 25 MHz, achievable via its internal PLL when driven by an external 8 MHz crystal. The PLL allows flexible clock scaling for balancing performance and power consumption in automotive applications where deterministic timing is critical. This frequency applies to the CPU12 core execution speed, independent of peripheral clock domains.

Does the S9S12G48F1CLC support CAN FD?

No, the S9S12G48F1CLC integrates the S12MSCANV3 module, which implements classical CAN 2.0B protocol only - supporting data frames up to 8 bytes and bit rates up to 1 Mbps. It does not support CAN FD features such as variable bit rate, extended data length (up to 64 bytes), or CRC enhancements. For CAN FD, designers must select newer S32K or SPC5 families.

Is the S9S12G48F1CLC pin-compatible with other MC9S12G variants?

Yes, the S9S12G48F1CLC in LQFP-64 package shares identical pinout with all MC9S12G family members in the same 64-pin footprint, including S9S12G64F1CLC and S9S12G96F1CLC. Pin assignments for power, ground, CAN, BDM, and primary I/O are fully consistent - enabling hardware reuse across Flash size variants during design scaling.

What debug interface does the S9S12G48F1CLC provide?

The S9S12G48F1CLC uses the Background Debug Module (BDM) interface via the BKGD pin, supporting single-wire serial communication for flash programming, register read/write, and real-time breakpoint debugging. It requires an NXP-compatible BDM pod (e.g., USB-ML-12) and Codewarrior IDE - no JTAG port is present on this device.

What is the Flash endurance specification for the S9S12G48F1CLC?

The S9S12G48F1CLC guarantees 100,000 erase/write cycles for its 48 KB on-chip Flash memory, validated under AEC-Q100 stress conditions. Each sector can be erased independently, and ECC circuitry transparently corrects single-bit errors during read operations - ensuring data integrity over the full automotive service life.
