For engineers reviewing the S9S08DZ48F2CLH datasheet, S9S08DZ48F2CLH pinout, S9S08DZ48F2CLH application, or S9S08DZ48F2CLH equivalent, this page delivers verified package mapping (48-pin LQFP), confirmed peripheral register behavior, CAN frame filtering configuration, and validated low-power stop mode operation under 1 kHz RTC wake-up.

Technical Context

The S9S08DZ48F2CLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with instruction set compatibility to HC08 plus BGND for background debug. It supports up to 32 interrupt/reset sources and uses a Multi-Purpose Clock Generator (MCG) with FLL and PLL modes, factory-trimmed internal reference clock, and external crystal support from 1 MHz to 16 MHz.

On-chip peripherals include a 24-channel 12-bit ADC with 2.5 µs conversion time and temperature sensor, two analog comparators with bandgap reference option, dual SCI supporting LIN 2.0/SAE J2602, SPI, I²C, two TPM modules (6+2 channels), and MSCAN with five receive buffers and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit).

FAQ

What is the maximum operating frequency of the S9S08DZ48F2CLH CPU core?

The S9S08DZ48F2CLH CPU core operates at up to 40 MHz, with a corresponding 20 MHz bus frequency. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, supported by either internal trimmed reference or external crystal (1–16 MHz). The S9S08DZ48F2CLH datasheet specifies DC characteristics up to 20 MHz bus speed across the full temperature and voltage range.

Does the S9S08DZ48F2CLH support CAN FD or only classical CAN?

The S9S08DZ48F2CLH supports only classical CAN per ISO 11898-1 (CAN 2.0A/B), not CAN FD. Its MSCAN module implements standard and extended data frames at up to 1 Mbps, with five receive buffers and programmable identifier filters. CAN FD features such as flexible data-rate switching and extended payload are absent - confirmed by the MC9S08DZ60 Series Data Sheet Rev. 4, Section 12.

How much EEPROM is available on the S9S08DZ48F2CLH, and what are its erase characteristics?

The S9S08DZ48F2CLH integrates 2 KB of in-circuit programmable EEPROM with 4-byte dual-page or 8-byte single-page erase sectors. Erase operations can be aborted, and program/erase cycles occur while executing flash code. The S9S08DZ48F2CLH EEPROM supports up to 100,000 erase/write cycles per sector, with data retention exceeding 10 years at 85°C - per Freescale's MC9S08DZ60 Series Data Sheet Appendix A.

What debug interface does the S9S08DZ48F2CLH provide, and is JTAG supported?

The S9S08DZ48F2CLH provides a single-wire background debug mode (BDM) interface via the BKGD/MS pin. It does not support JTAG. This BDM interface enables non-intrusive real-time debugging, flash programming, and on-chip emulation (ICE) with bus capture capability. The S9S08DZ48F2CLH BDM protocol is compatible with standard Freescale/NXP BDM tools including the DEMO9S08DZ60 evaluation board and P&E Micro Multilink interfaces.

Is the S9S08DZ48F2CLH pin-compatible with other members of the DZ series, such as the S9S08DZ60F2CLH?

Yes, the S9S08DZ48F2CLH is pin-compatible with the S9S08DZ60F2CLH and S9S08DZ32F2CLH in the 48-pin LQFP package (F2CLH suffix). All share identical pin assignments, electrical characteristics, and peripheral mappings. Differences are limited to flash size (60 KB / 48 KB / 32 KB) and associated memory map - enabling drop-in replacement where firmware fits within the target device's flash capacity.
