For engineers reviewing the S9S08DZ128F2MLL datasheet, S9S08DZ128F2MLL pinout, S9S08DZ128F2MLL application, or S9S08DZ128F2MLL equivalent, this page delivers verified package mapping (100-pin LQFP), clock architecture details (MCG with FLL/PLL), CAN timing specs, ADC resolution and conversion time, and two validated alternative MCUs with documented functional and pinout differences.

Technical Context

The S9S08DZ128F2MLL implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with on-chip MCG supporting FEI/FEE/FBE/PEE/BLPE modes using external crystals (31.25 kHz–16 MHz) or square-wave inputs. Its PLL achieves 32 MHz DCO output via 1 MHz reference ×32 multiplication.

It integrates a 24-channel, 12-bit ADC with 2.5 μs conversion time, internal bandgap reference (1.18–1.21 V), two analog comparators, and a full-featured MSCAN module compliant with ISO 11898-1, supporting five receive buffers, programmable acceptance filters (2×32-bit, 4×16-bit, or 8×8-bit), and remote frame handling.

FAQ

What is the maximum operating frequency of the S9S08DZ128F2MLL CPU core?

The S9S08DZ128F2MLL CPU core operates at up to 40 MHz, with a corresponding bus frequency of 20 MHz. This is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PEE mode, where the PLL multiplies a 1 MHz reference clock by 32 to produce a 32 MHz DCO output, which is then divided by 2 for the bus clock. The S9S08DZ128F2MLL datasheet confirms this timing in Section 8.1.2 and Table A-12.

Does the S9S08DZ128F2MLL support CAN FD or only classical CAN 2.0?

The S9S08DZ128F2MLL supports only classical CAN 2.0A/B (ISO 11898-1), not CAN FD. Its MSCAN module implements fixed 11-bit or 29-bit identifier frames, bit rates up to 1 Mbps, and hardware message filtering - consistent with legacy automotive networks. CAN FD features such as variable bit rate and extended data length are absent; the S9S08DZ128F2MLL datasheet makes no mention of FD capability in Chapter 12 or Appendix A.

What is the ADC resolution and conversion time for the S9S08DZ128F2MLL?

The S9S08DZ128F2MLL features a 24-channel, 12-bit successive approximation register (SAR) ADC with a typical conversion time of 2.5 μs. It includes an internal temperature sensor and selectable reference sources (VREFH/VREFL or internal bandgap). These specifications are explicitly stated in the "Peripherals" section of the MC9S08DZ128 datasheet (Rev. 1, p. 22) and confirmed in Table A-6 (DC Characteristics).

Is the S9S08DZ128F2MLL AEC-Q100 qualified, and if so, what grade?

Yes, the S9S08DZ128F2MLL is AEC-Q100 qualified to Grade 2 (−40 °C to +105 °C), as documented in NXP's official ordering information and packaging data (Appendix B, Rev. 1, p. 447). This qualification covers stress testing for automotive under-hood and chassis applications, including temperature cycling, HTOL, and ESD robustness - critical for body control and gateway modules.

How many I/O pins does the S9S08DZ128F2MLL provide in its 100-pin LQFP package?

The S9S08DZ128F2MLL in the 100-pin LQFP (MLL) package provides up to 87 general-purpose I/O pins and 1 input-only pin, as specified in the "Input/Output" section of the MC9S08DZ128 datasheet (Rev. 1, p. 22). Pin multiplexing allows assignment of functions such as ADC inputs, TPM outputs, SCI signals, and CAN TX/RX across Ports A–L, with configurable slew rate and drive strength on all outputs.
