NXP Semiconductors S9S08DZ96F2CLH

Overview

S9S08DZ96F2CLH 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 applications requiring robust real-time communication and mixed-signal processing.

For engineers reviewing the S9S08DZ96F2CLH datasheet, S9S08DZ96F2CLH pinout, S9S08DZ96F2CLH application, or S9S08DZ96F2CLH equivalent, key selection considerations include its 48-pin LQFP package, 20 MHz bus frequency, on-chip 12-bit 24-channel ADC with temperature sensor, dual SCI supporting LIN 2.0/SAE J2602, and MSCAN module with five receive buffers and programmable identifier filters.

Technical Context

The S9S08DZ96F2CLH implements the HCS08 CPU core operating at up to 40 MHz core clock (20 MHz bus), with a Multi-Purpose Clock Generator (MCG) supporting FEI, FEE, FBE, PEE, and BLPE modes - enabling flexible clock sourcing from internal RC, external crystal (31.25 kHz–16 MHz), or square-wave inputs. It integrates a single-wire background debug interface and on-chip ICE for real-time bus capture.

Its peripheral set includes three Timer Pulse-Width Modulators (TPM1: 6-channel, TPM2: 2-channel, TPM3: 4-channel), two analog comparators with bandgap reference, and a real-time counter with 1 kHz low-power oscillator - all operable in stop3 mode. The MSCAN module supports standard/extended frames, remote frames, and FIFO-based reception with configurable acceptance filtering.

FAQ

What is the maximum bus frequency supported by the S9S08DZ96F2CLH?

The S9S08DZ96F2CLH 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 PLL multiplier = 32 MHz core → 16 MHz bus, or optimized for 20 MHz bus). All timing specifications in the datasheet assume operation at this rated bus speed.

Does the S9S08DZ96F2CLH include a hardware CAN controller?

Yes, the S9S08DZ96F2CLH integrates the MSCAN module - a fully compliant Controller Area Network controller supporting CAN 2.0A and 2.0B protocols. It provides five receive buffers with FIFO storage, programmable identifier acceptance filters (configurable as 2×32-bit, 4×16-bit, or 8×8-bit), and support for standard/extended data frames and remote frames - all implemented in hardware without CPU intervention during message handling.

What are the power supply requirements for the S9S08DZ96F2CLH?

The S9S08DZ96F2CLH operates from a single supply voltage ranging from 2.7 V to 5.5 V, with full specification compliance across this range. It includes internal voltage regulation and low-voltage detection circuitry that can generate reset or interrupt events at user-selectable thresholds. The device draws typical active current of 7 mA at 5 V/20 MHz and reduces to <1 µA in Stop3 mode - making it suitable for battery-powered and energy-conscious applications.

Can the S9S08DZ96F2CLH perform ADC conversions while in low-power stop modes?

No, the ADC module is disabled in all stop modes (Stop2 and Stop3) and cannot perform conversions. However, the S9S08DZ96F2CLH supports wake-up from Stop3 mode via external interrupt, RTC alarm, or low-voltage detect event - allowing rapid transition to Run mode where ADC operation resumes. The real-time counter and certain comparator functions remain active in Stop3 mode, but analog-to-digital conversion requires active bus clocking.

Is the S9S08DZ96F2CLH pin-compatible with other members of the MC9S08DZ series?

Yes, the S9S08DZ96F2CLH in the 48-pin LQFP package shares identical pin assignments with the MC9S08DZ128F2CLH, MC9S08DV96F2CLH, and MC9S08DV128F2CLH - as confirmed in Table 2-1 of the MC9S08DZ128 Series Data Sheet. This allows direct substitution within the same package variant, provided firmware accommodates differences in FLASH size, RAM capacity, and EEPROM presence.
