NXP Semiconductors S9S08DZ96F2MLF

Overview

S9S08DZ96F2MLF 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 S9S08DZ96F2MLF datasheet, S9S08DZ96F2MLF pinout, S9S08DZ96F2MLF application, or S9S08DZ96F2MLF equivalent, this page delivers verified package mapping (64-pin LQFP), clock architecture details (MCG with FLL/PLL), DC characteristics (1.18–1.21 V bandgap reference), CAN timing compliance, and validated alternative part options for design continuity.

Technical Context

The S9S08DZ96F2MLF 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, and PBE modes using internal trimmed reference or external crystal/resonator (1–16 MHz). Its MCG includes nonvolatile trim (0.2% resolution, ±1.5% temp stability) and DIV32 control for FLL scaling in high-range oscillator configurations.

It integrates a 24-channel 12-bit ADC with 2.5 µs conversion time, two analog comparators with bandgap reference option, and a full-featured MSCAN module compliant with ISO 11898-1:2003 supporting standard/extended frames, five receive buffers with FIFO, and programmable acceptance filters (2×32-bit, 4×16-bit, or 8×8-bit).

FAQ

What is the maximum bus frequency supported by the S9S08DZ96F2MLF?

The S9S08DZ96F2MLF supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a fixed 2:1 divider. This frequency is achievable in PEE mode using the internal PLL with a 1–16 MHz external crystal and appropriate MCG register configuration (e.g., RDIV=8, VDIV=32 yielding 32 MHz DCO → 16 MHz FLL output → 20 MHz bus via prescaler). The S9S08DZ96F2MLF datasheet specifies this as the rated operational limit under all valid voltage and temperature conditions.

Does the S9S08DZ96F2MLF include an internal voltage reference for the ADC?

Yes, the S9S08DZ96F2MLF includes an internal bandgap voltage reference with a nominal value of 1.20 V and a specified range of 1.18–1.21 V (min–max) across temperature and supply voltage. This reference is factory-trimmed at VDD = 5.0 V and is used automatically when the ADC's VREFH/VREFL pins are unconnected or configured for internal reference mode. It enables ratiometric or absolute measurements without external components, and the S9S08DZ96F2MLF supports dedicated ADC channel selection for monitoring this reference during runtime.

Can the S9S08DZ96F2MLF operate in low-power stop modes while maintaining CAN bus activity?

No - the S9S08DZ96F2MLF cannot maintain active CAN communication in Stop2 or Stop3 modes. While the MSCAN module retains message buffers and filter settings in Stop2, it cannot receive or transmit frames without CPU intervention or clock domain activation. In Stop3 mode, only the 1-kHz RTC oscillator remains active; CAN functionality is fully disabled. Wake-up from stop requires external interrupt or RTC alarm, after which the S9S08DZ96F2MLF must reinitialize MCG and MSCAN before resuming CAN operations.

What debug interface does the S9S08DZ96F2MLF support?

The S9S08DZ96F2MLF supports a single-wire Background Debug Mode (BDM) interface via the BKGD/MS pin. This interface enables full in-circuit debugging including breakpoint setting, memory read/write, register inspection, and flash programming without halting real-time peripheral operation. It requires a compatible BDM pod (e.g., PEMicro Cyclone or NXP DEMO9S08DZ60) and is documented in Chapter 17 of the MC9S08DZ128 Series Data Sheet. The S9S08DZ96F2MLF does not support JTAG or SWD.

Is the S9S08DZ96F2MLF pin-compatible with other members of the MC9S08DZ series?

Yes - the S9S08DZ96F2MLF is pin-compatible with the S9S08DZ128F2MLF in the 64-pin LQFP package, sharing identical pin assignments, electrical characteristics, and peripheral mappings. Both devices use the same MC9S08DZ128 Series Data Sheet (Rev. 1, 2008) and Addenda (Rev. 2, 2015). Differences are limited to flash (96 KB vs. 128 KB) and RAM (6 KB vs. 8 KB) capacity; no PCB redesign is required when upgrading between these two variants.
