FAQ

What is the maximum operating frequency of the MC9S08DV128MLH CPU core?

The MC9S08DV128MLH CPU core runs at up to 40 MHz, with a corresponding bus clock of 20 MHz. This frequency is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PEE mode with appropriate RDIV and VDIV settings. The MC9S08DV128MLH datasheet specifies this as the absolute maximum rated performance under 5.0 V and 25°C conditions, with derating applied across the full –40°C to +125°C temperature range.

Does the MC9S08DV128MLH include on-chip EEPROM memory?

No, the MC9S08DV128MLH does not include on-chip EEPROM. Unlike the MC9S08DZ128MLH variant, which integrates 2 KB of EEPROM, the DV128 relies solely on its 128 KB Flash for nonvolatile storage. However, Freescale provides Flash EEPROM emulation libraries enabling wear-leveling and byte-write functionality within designated Flash sectors - a common practice for MC9S08DV128MLH-based designs requiring parameter retention.

What CAN protocol versions does the MC9S08DV128MLH support?

The MC9S08DV128MLH supports Controller Area Network (CAN) protocol Version 2.0A and 2.0B, compliant with ISO 11898-1:2003. Its MSCAN module handles both standard (11-bit) and extended (29-bit) identifier frames, supports remote transmission requests, and implements five receive buffers with FIFO behavior. The MC9S08DV128MLH does not support CAN FD or higher-layer protocols like CANopen or J1939 - those require external protocol stacks or more advanced MCUs.

Can the MC9S08DV128MLH operate from a 3.3 V supply?

Yes, the MC9S08DV128MLH operates across a supply voltage range of 2.7 V to 5.5 V, making 3.3 V fully supported. At 3.3 V, the maximum guaranteed bus frequency is 16 MHz (per electrical characteristics tables), and all peripherals - including ADC, CAN, and timers - remain functional. The MC9S08DV128MLH internal voltage regulator and bandgap reference maintain specified accuracy across this range, ensuring reliable operation in mixed-voltage automotive subsystems.

Is the MC9S08DV128MLH pin-compatible with other HCS08 family members?

The MC9S08DV128MLH shares identical pinout and package dimensions (100-pin LQFP) with the MC9S08DZ128MLH and S9S08DZ128F2MLH, enabling direct PCB reuse across these variants. However, functional differences exist - notably the absence of EEPROM in DV128 and variations in Flash sector size and COP features. Therefore, while mechanical replacement is possible, firmware and power design must be validated for each specific part before substitution.
