FAQ

What is the maximum operating frequency of the S9S08DV16F1MLC CPU core?

The S9S08DV16F1MLC CPU core operates at up to 40 MHz, while its system bus runs at 20 MHz. This architecture allows efficient instruction execution while maintaining timing margins for peripheral access and deterministic interrupt response - essential for real-time automotive control tasks handled by the S9S08DV16F1MLC.

Does the S9S08DV16F1MLC support CAN FD or only classical CAN?

The S9S08DV16F1MLC supports only classical CAN 2.0A/B protocol via its MSCAN module and does not implement CAN FD features such as variable bit rates or extended data length. Its five receive buffers with FIFO and flexible identifier filtering are optimized for standard 11-/29-bit identifier messaging at up to 1 Mbps - consistent with the specification of the S9S08DV16F1MLC.

What package type and pin count does the S9S08DV16F1MLC use?

The S9S08DV16F1MLC is packaged in a 48-pin LQFP (7×7 mm) with exposed pad, rated for operation from −40°C to 105°C. This package matches the mechanical and thermal requirements of automotive under-hood and cabin applications and is explicitly listed in the MC9S08DV60 Series Data Sheet Rev 3 for the S9S08DV16F1MLC variant.

How much RAM is available on the S9S08DV16F1MLC?

The S9S08DV16F1MLC includes 2 KB of on-chip RAM, allocated for stack operations, peripheral register shadowing, CAN message buffering, and runtime variables. This RAM size is confirmed in the "On-Chip Memory" section of the official datasheet and is sufficient for deterministic real-time execution of automotive body control firmware running on the S9S08DV16F1MLC.

Is the S9S08DV16F1MLC qualified for automotive applications?

Yes, the S9S08DV16F1MLC is AEC-Q100 qualified for automotive use and specified for operation across −40°C to 105°C ambient temperature. It includes automotive-grade features such as low-voltage detection with interrupt/reset, COP watchdog with backup clock, flash block protection, and robust EMC performance - all validated per the S9S08DV16F1MLC product definition.
