Overview

S9S08DZ96F2MLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB flash, 6 KB RAM, and integrated CAN 2.0A/B controller, ADC, TPM, SCI, SPI, I²C, and RTC - designed for automotive body electronics and industrial control requiring robust real-time communication and mixed-signal processing.

For engineers reviewing the S9S08DZ96F2MLH datasheet, S9S08DZ96F2MLH pinout, S9S08DZ96F2MLH application, or S9S08DZ96F2MLH equivalent, this page delivers verified electrical specs, package mapping, clock configuration details, CAN timing constraints, and validated alternative parts for automotive ECU and motor control designs.

Technical Context

The S9S08DZ96F2MLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with a Multi-Purpose Clock Generator supporting FEI/FEE/FBE/PEE/BLPE modes, internal bandgap reference (1.18–1.21 V), and programmable trim for ±1.5% frequency stability over temperature. Its MCG supports external crystals from 31.25 kHz to 16 MHz with configurable RDIV and DIV32 dividers.

It integrates MSCAN with five receive buffers, FIFO storage, and flexible identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit), plus a 24-channel 12-bit ADC with 2.5 µs conversion time, temperature sensor, and internal bandgap reference channel - all operable in low-power stop3 mode.

FAQ

What is the maximum bus frequency supported by the S9S08DZ96F2MLH?

The S9S08DZ96F2MLH supports a maximum bus frequency of 20 MHz, derived from its 40-MHz core clock via a fixed 2:1 divider. This frequency is achievable in PEE mode using the PLL with appropriate MCG configuration (e.g., 8 MHz crystal → 1 MHz reference → ×32 → 32 MHz core → 20 MHz bus after prescaling). The S9S08DZ96F2MLH datasheet confirms stable operation up to 20 MHz across the full industrial temperature range (−40°C to +105°C) with VDD = 4.5–5.5 V.

Does the S9S08DZ96F2MLH support CAN FD or only classical CAN?

The S9S08DZ96F2MLH implements the MSCAN module compliant exclusively with ISO 11898-1:2003 (Classical CAN 2.0A/B), supporting standard and extended frames up to 1 Mbps. It does not support CAN FD features such as flexible data-rate, longer payloads, or CRC enhancements. The S9S08DZ96F2MLH MSCAN hardware lacks the baudrate switching logic and enhanced DLC handling required for CAN FD, and no firmware patch or configuration enables FD mode.

What is the purpose of the DIV32 bit in the MCGC3 register of the S9S08DZ96F2MLH?

The DIV32 bit (bit 4) in MCGC3 enables a divide-by-32 factor applied to the external reference clock before FLL input when RANGE = 1, allowing use of high-frequency crystals (e.g., 8 MHz) while keeping the FLL reference within its 31.25–39.0625 kHz operating window. The S9S08DZ96F2MLH requires DIV32 = 1 for 8 MHz crystals in FEE/FBE modes; it must be cleared when PLLS = 1 (PEE/PBE modes), as confirmed in the MC9S08DZ128 addendum Rev. 2.

Can the S9S08DZ96F2MLH operate from a 3.3 V supply?

No, the S9S08DZ96F2MLH is specified only for 4.5–5.5 V operation per its DC characteristics table (Appendix A). Its internal bandgap reference (1.18–1.21 V), flash programming voltage, and I/O thresholds are calibrated for 5 V nominal supply. Operating below 4.5 V risks unreliable flash writes, ADC inaccuracies, and undefined reset behavior. The S9S08DZ96F2MLH does not support 3.3 V operation - use NXP's SKEAZ series for true 3.3 V 8-bit MCUs.

How many CAN message buffers does the S9S08DZ96F2MLH support?

The S9S08DZ96F2MLH MSCAN module provides five dedicated receive buffers with FIFO storage capability, plus one transmit buffer. These buffers support prioritized message handling and automatic ID filtering via programmable acceptance masks. The S9S08DZ96F2MLH allows configuration of filter schemes as 2×32-bit, 4×16-bit, or 8×8-bit identifiers - enabling selective reception of up to five concurrent CAN IDs without CPU intervention.
