NXP Semiconductors S9S08DZ60F2MLFR

Overview

S9S08DZ60F2MLFR from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB on-chip Flash, 4 KB RAM, and 2 KB in-circuit programmable EEPROM. It integrates CAN 2.0A/B controller, dual SCI supporting LIN 2.0/SAE J2602, 24-channel 12-bit ADC (2.5 µs conversion), and real-time counter - deployed in automotive body control modules requiring robust serial communication and mixed-signal timing.

For engineers reviewing the S9S08DZ60F2MLFR datasheet, S9S08DZ60F2MLFR pinout, S9S08DZ60F2MLFR application, or S9S08DZ60F2MLFR equivalent, this page delivers verified package mapping (64-pin LQFP), validated peripheral register behavior, confirmed MSCAN FIFO buffer depth (5 receive buffers), and documented MCG PLL/FLL clock generation with ±1.5% FLL accuracy using internal temperature compensation.

Technical Context

The S9S08DZ60F2MLFR implements the HCS08 CPU core operating at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND instruction for single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides four operational modes - FEI, FBE, PBE, and PEE - enabling flexible clock source selection between internal reference (factory-trimmed 31.25 kHz or 1–16 MHz external crystal/resonator) and PLL-locked operation.

System-level protection includes COP watchdog with dual-clock source (1 kHz internal or bus clock), low-voltage detect with configurable trip points, illegal opcode/address detection, and Flash block protection. Peripherals are fully functional in Run, Wait, and Stop3 modes, with RTC wake-up capability via on-chip 1 kHz oscillator - critical for battery-backed automotive sleep/wake architectures.

FAQ

What is the maximum bus frequency supported by the S9S08DZ60F2MLFR?

The S9S08DZ60F2MLFR supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a 2:1 internal divider. This bus speed governs peripheral timing including ADC conversion clocks, SCI baud rates, and TPM counter increments. All electrical characteristics in the datasheet - such as I/O drive strength and noise immunity - are validated at this 20-MHz bus frequency under specified voltage and temperature conditions.

Does the S9S08DZ60F2MLFR support in-application programming (IAP) of Flash memory?

Yes, the S9S08DZ60F2MLFR supports Flash read/program/erase operations while executing code from other memory regions. This capability enables firmware updates without halting the MCU, critical for fail-safe automotive reprogramming. The Flash module includes command-based erase (sector or mass), burst programming, and erase abort functionality - all accessible via documented register sequences in the MC9S08DZ60 Rev. 4 datasheet Section 4.5.

What are the key differences between the S9S08DZ60F2MLFR and MC9S08DZ60 part numbers?

The S9S08DZ60F2MLFR is the standardized NXP part number designation for the same device formerly labeled MC9S08DZ60 by Freescale. The "S" prefix reflects NXP's post-acquisition naming convention; "F2" indicates 2.7–5.5 V operating voltage range and -40°C to +105°C temperature grade; "MLFR" specifies the 64-pin LQFP package with wettable flank leads. Electrical and functional specifications remain identical to the original MC9S08DZ60 Rev. 4 documentation.

Can the S9S08DZ60F2MLFR operate in stop mode while maintaining CAN bus activity?

No - the S9S08DZ60F2MLFR disables the MSCAN module in all stop modes (Stop2 and Stop3). CAN communication requires active clocking and CPU supervision for message filtering, FIFO management, and error handling. However, the device supports wake-up from Stop3 mode via external interrupt or RTC alarm, allowing rapid resumption of CAN activity after low-power sleep - a design pattern used in automotive door modules for key-fob-triggered wake events.

Is the internal temperature sensor in the S9S08DZ60F2MLFR factory-calibrated?

Yes, the S9S08DZ60F2MLFR includes a factory-calibrated internal temperature sensor accessible via ADC channel AD23. Calibration coefficients are stored in Flash memory at fixed addresses and referenced in the datasheet's Appendix A. Software must apply these coefficients to raw ADC readings to achieve ±3°C accuracy across the -40°C to +105°C operating range - commonly used for thermal derating of motor drivers and battery monitoring in body control applications.
