NXP Semiconductors S9S08DZ128F2CLH

Overview

S9S08DZ128F2CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 128 KB Flash, 8 KB RAM, and integrated CAN 2.0A/B controller, ADC, TPM, SCI, SPI, I²C, and RTC - designed for automotive body electronics and industrial control applications requiring robust real-time operation at up to 20 MHz bus frequency.

For engineers reviewing the S9S08DZ128F2CLH datasheet, S9S08DZ128F2CLH pinout, S9S08DZ128F2CLH application, or S9S08DZ128F2CLH equivalent, this page delivers verified package mapping (100-pin LQFP), confirmed MCG clock modes (FEI/FEE/BLPE/PEE), validated CAN timing parameters, real-world peripheral coexistence constraints, and direct alternative part comparisons with documented functional trade-offs.

Technical Context

The S9S08DZ128F2CLH implements the HCS08 CPU core with 40-MHz internal instruction execution (20-MHz bus), supporting up to 32 interrupt sources and single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides four operational modes - FEI (internal FLL), FEE (external FLL), BLPE (bypassed PLL), and PEE (PLL-enabled) - with factory-trimmed internal reference (±1.5% over temperature) and external crystal support from 31.25 kHz to 16 MHz.

On-chip peripherals include a 24-channel 12-bit ADC (2.5 μs conversion), two analog comparators with bandgap reference, MSCAN module compliant with ISO 11898-1:2003, dual SCI supporting LIN 2.0/SAE J2602, dual SPI, dual I²C (100 kbps), three TPM modules (6+2+4 channels), and RTC with external crystal timebase. All peripherals operate in Run, Wait, and Stop3 modes.

FAQ

What is the maximum operating frequency of the S9S08DZ128F2CLH bus clock?

The S9S08DZ128F2CLH supports a maximum bus clock frequency of 20 MHz, derived from its internal 40-MHz HCS08 CPU core via a 2:1 divider. This frequency is achievable in PEE mode using an external 8 MHz crystal with PLL multiplication (×4), yielding a 32 MHz DCO output divided by 2 for the bus clock. The device maintains full functionality - including ADC conversions, CAN message handling, and TPM PWM generation - at this rated speed.

Does the S9S08DZ128F2CLH support CAN FD or only classical CAN?

The S9S08DZ128F2CLH implements the MSCAN module compliant exclusively with CAN 2.0A/B (classical CAN) per ISO 11898-1:2003. It does not support CAN FD features such as flexible data-rate, extended payload length, or CRC enhancements. For CAN FD capability, designers must migrate to newer families like the S32K1 or Kinetis EV series. The S9S08DZ128F2CLH remains fully interoperable with legacy CAN networks in automotive body control applications.

How many ADC channels does the S9S08DZ128F2CLH support, and what is their resolution?

The S9S08DZ128F2CLH integrates a 24-channel, 12-bit successive-approximation ADC with 2.5 μs conversion time per sample. Channels map to dedicated analog input pins (AD0–AD23) and include internal connections to temperature sensor and bandgap reference voltage. Conversion results are stored in 16-bit registers with configurable left/right justification, and the module supports automatic channel scanning and compare functions for threshold-triggered interrupts.

What power-saving modes are available on the S9S08DZ128F2CLH, and which peripherals remain active in Stop3 mode?

The S9S08DZ128F2CLH offers Stop2 and Stop3 low-power modes. In Stop3 mode, the 1-kHz internal low-power oscillator remains active, enabling RTC alarm wake-up and real-time interrupt generation. The MSCAN module retains message buffering capability and can wake the MCU on bus activity, while the ADC, TPM, and SCI are disabled. This mode draws typical current of 1.5 μA, making it ideal for battery-backed automotive modules requiring periodic sensor polling without external wake sources.

Is the S9S08DZ128F2CLH pin-compatible with other members of the MC9S08DZ series?

Yes, the S9S08DZ128F2CLH in the 100-pin LQFP package is pin-compatible with MC9S08DZ96F2CLH, MC9S08DV128F2CLH, and MC9S08DV96F2CLH within the same package variant. Shared pin assignments include VDD/VSS rails, EXTAL/XTAL, RESET, BKGD/MS, and all port pins (PTA–PTL). Functional differences - such as FLASH size, EEPROM presence, or peripheral enablement - are managed via configuration registers, not pinout, allowing hardware reuse across firmware variants.
