FAQ

What is the maximum operating frequency of the S9S08DV32F2MLC CPU core?

The S9S08DV32F2MLC CPU core operates at up to 40 MHz, with a corresponding 20 MHz bus clock frequency. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is fully supported across the device's rated voltage (4.5–5.5 V) and temperature (–40°C to +125°C) ranges as specified in the MC9S08DV60 Series Data Sheet Rev 3.

Does the S9S08DV32F2MLC support CAN FD or only classical CAN?

The S9S08DV32F2MLC supports only classical CAN protocol versions 2.0A and 2.0B, as implemented in its MSCAN module. It does not support CAN FD features such as increased data rates or extended payload length. The S9S08DV32F2MLC MSCAN module complies with ISO 11898-1 and supports standard and extended identifiers, remote frames, and programmable acceptance filtering.

What is the ADC resolution and conversion time for the S9S08DV32F2MLC?

The S9S08DV32F2MLC integrates a 12-bit successive-approximation ADC with 16 input channels, achieving a typical conversion time of 2.5 μs. It includes an internal temperature sensor and bandgap reference channel, and supports automatic compare functions to reduce CPU intervention during threshold monitoring tasks.

Is the S9S08DV32F2MLC pin-compatible with other devices in the DV-series?

Yes - the S9S08DV32F2MLC in the 48-pin LQFP package shares identical pinout with MC9S08DV48F2MLC and MC9S08DV16F2MLC. This enables direct hardware scalability across flash variants without PCB redesign, provided the same package option (F2MLC = 48-pin LQFP) is selected for all variants.

What debug interface does the S9S08DV32F2MLC use, and what tools support it?

The S9S08DV32F2MLC uses a single-wire background debug (BKGD) interface compliant with the HCS08 architecture. It is supported by NXP's S08 Cyclone Pro, USB-ML-PP, and compatible third-party debug probes. No external JTAG header is required, and the interface operates through the BKGD/MS pin, enabling in-circuit programming and real-time emulation without disrupting system signals.
