It operates at up to 40 MHz CPU / 20 MHz bus frequency and supports automotive-grade temperature range (–40°C to +125°C) in a 64-pin LQFP package.

For engineers reviewing the MC9S08DZ96MLH datasheet, MC9S08DZ96MLH pinout, MC9S08DZ96MLH application, or MC9S08DZ96MLH equivalent, this page delivers verified technical context, validated pin assignments, real-world use cases in CAN-based vehicle subsystems, and actionable alternative selection guidance for ECU design continuity.

Technical Context

The MC9S08DZ96MLH implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) supports FEI, FEE, FBE, PEE, and BLPE modes with internal reference trimming (±1.5% over temperature) and external crystal/resonator input up to 16 MHz (RANGE=1, HGO=1).

On-chip peripherals include a 24-channel 12-bit ADC with 2.5 µs conversion time and internal bandgap reference (1.18–1.21 V), two analog comparators operational in STOP3 mode, and a fully compliant CAN 2.0A/B controller with five receive buffers and programmable acceptance filters (2×32-bit, 4×16-bit, or 8×8-bit).

Key Specifications

FAQ

What is the maximum operating frequency of the MC9S08DZ96MLH CPU and bus?

The MC9S08DZ96MLH features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus frequency of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PEE mode with appropriate PLL configuration (e.g., 8 MHz crystal → 1 MHz reference → ×32 = 32 MHz DCO → ÷2 bus divider). The MC9S08DZ96MLH datasheet specifies these values under DC characteristics and MCG specifications sections.

Does the MC9S08DZ96MLH support CAN FD or only classical CAN 2.0?

The MC9S08DZ96MLH integrates the MSCAN module, which implements ISO 11898-1 (CAN 2.0A/B) only - it does not support CAN FD. Its MSCAN controller handles standard and extended data frames, remote frames, and five receive buffers with flexible identifier filtering, but lacks the bit-rate switching, extended data length, and CRC enhancements defined in CAN FD. For CAN FD requirements, newer NXP S32K or Kinetis families must be considered instead of the MC9S08DZ96MLH.

What is the purpose of the DIV32 bit in the MCGC3 register of the MC9S08DZ96MLH?

In the MC9S08DZ96MLH, the DIV32 bit (bit 4) in MCGC3 enables a divide-by-32 factor applied to the external reference clock before FLL input - but only when RANGE = 1 (high-frequency crystal mode). It must be cleared when PLLS = 1 (i.e., PLL selected), as stated in the MC9S08DZ128 Series Addendum Rev. 2. This ensures proper FLL/PLL reference frequency alignment (e.g., 8 MHz crystal ÷ 32 = 250 kHz for FLL, or ÷ 8 = 1 MHz for PLL), directly affecting bus clock stability and startup behavior in FEI-to-PEE transitions.

Can the MC9S08DZ96MLH operate in stop mode while maintaining CAN bus activity?

No - the MC9S08DZ96MLH cannot maintain active CAN communication in any stop mode. While its MSCAN module supports wake-up on CAN bus activity (e.g., dominant edge), the CAN controller itself is disabled in STOP2 and STOP3 modes per Section 3.6.3 of the MC9S08DZ128 Series Data Sheet. CAN reception and transmission require active clocking and CPU supervision, which are suspended in stop states. Wake-up events trigger exit to run/wait mode before CAN processing resumes.

What packaging and lead finish does the MC9S08DZ96MLH use?

The MC9S08DZ96MLH is supplied in a 64-pin low-profile quad flat-pack (LQFP) package measuring 10 mm × 10 mm with 0.5 mm pitch, per ordering information in Appendix B of the MC9S08DZ128 Series Data Sheet. It uses a lead-free (Pb-free), RoHS-compliant matte tin (Sn) lead finish, qualified for reflow soldering per JEDEC J-STD-020 standards. The "LH" suffix in the part number explicitly denotes this LQFP package variant.
