Overview

MC9S08DZ96CLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB on-chip FLASH, 6 KB RAM, and 2 KB EEPROM, featuring integrated MSCAN, dual SCI/LIN, dual SPI, dual I²C, three TPM modules (6+2+4 channels), 12-bit 24-channel ADC, RTC, and analog comparators. It operates at up to 40 MHz CPU / 20 MHz bus frequency and targets automotive body electronics and industrial control applications requiring CAN communication and robust mixed-signal integration.

For engineers reviewing the MC9S08DZ96CLF datasheet, MC9S08DZ96CLF pinout, MC9S08DZ96CLF application, or MC9S08DZ96CLF equivalent, key selection considerations include its 64-pin LQFP package, CAN 2.0A/B compliance, internal bandgap reference (1.18–1.21 V), PLL/FLL clock generation with external crystal support up to 16 MHz, and single-wire background debug interface.

Technical Context

The MC9S08DZ96CLF implements the HCS08 CPU core with HC08 instruction set extension and BGND instruction, supporting up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides FEI, FEE, FBE, PEE, PBE, and BLPE modes with factory-trimmed internal reference (±1.5% over temperature) and DIV32-enabled external clock division for high-range crystals.

Peripherals include a 12-bit ADC with 2.5 µs conversion time and temperature sensor channel, two analog comparators with bandgap reference option and stop-mode operation, and MSCAN with five receive buffers, programmable acceptance filters (2×32-bit/4×16-bit/8×8-bit), and full CAN 2.0A/B protocol support including remote frames and extended data frames.

Key Specifications

FAQ

What is the maximum operating frequency of the MC9S08DZ96CLF CPU and bus?

The MC9S08DZ96CLF features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus frequency of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PEE mode with appropriate PLL configuration (e.g., 8 MHz crystal ×32 = 256 MHz DCO ÷8 = 32 MHz ÷2 = 16 MHz bus, or optimized for 20 MHz). The MC9S08DZ96CLF datasheet specifies these limits under DC characteristics and MCG specifications.

Does the MC9S08DZ96CLF support CAN 2.0B extended frames?

Yes, the MC9S08DZ96CLF's integrated MSCAN module fully supports CAN 2.0B, including both standard (11-bit) and extended (29-bit) identifier frames, as well as remote transmission requests and error frame handling. Its five receive buffers and programmable acceptance filters (configurable as 2×32-bit, 4×16-bit, or 8×8-bit) allow flexible message prioritization and filtering - all confirmed in Section 12 of the MC9S08DZ128 Series Data Sheet.

What is the accuracy of the internal bandgap voltage reference in the MC9S08DZ96CLF?

The MC9S08DZ96CLF provides an internal bandgap voltage reference of 1.18–1.21 V (typical 1.20 V) across temperature and supply voltage, as specified in Parameter 24 of the DC Characteristics table (Appendix A). This reference is factory trimmed at VDD = 5.0 V and used by the ADC and analog comparators - enabling stable measurements without external precision references.

Can the MC9S08DZ96CLF operate in low-power stop modes while retaining CAN or RTC functionality?

Yes, the MC9S08DZ96CLF supports Stop3 mode where the RTC remains active using either an external 32.768 kHz crystal or the internal 1 kHz low-power oscillator, enabling timed wake-up without external components. However, MSCAN is disabled in all stop modes per Section 3.6.3; CAN activity requires Run or Wait mode. The MC9S08DZ96CLF's RTC wake-up capability is explicitly documented for cyclic task scheduling in low-power applications.

Is the MC9S08DZ96CLF pin-compatible with other members of the DZ-series like the MC9S08DZ128CLF?

Yes, the MC9S08DZ96CLF is pin-compatible with the MC9S08DZ128CLF in the 64-pin LQFP package - sharing identical pin assignments, peripheral mappings, and electrical characteristics. This allows direct substitution where increased FLASH/RAM capacity is needed, with no PCB changes required. The compatibility is verified in Table 2-1 (Pin Assignments) and Package Options section of the MC9S08DZ128 Series Data Sheet.
