NXP Semiconductors MC9S08DZ96CLH

Overview

MC9S08DZ96CLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 96 KB on-chip FLASH, 6 KB RAM, and integrated CAN 2.0A/B controller, ADC, TPM, SCI, SPI, I²C, and RTC. It operates at up to 40 MHz CPU / 20 MHz bus frequency and supports multiple low-power modes including Stop2 and Stop3. It targets automotive body electronics and industrial control systems requiring robust communication and real-time analog processing.

For engineers reviewing the MC9S08DZ96CLH datasheet, MC9S08DZ96CLH pinout, MC9S08DZ96CLH application, or MC9S08DZ96CLH equivalent, key selection considerations include its 64-pin LQFP package, 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 MC9S08DZ96CLH implements the HCS08 CPU core with HC08 instruction set extension and BGND debug instruction. Its Multi-Purpose Clock Generator (MCG) supports FEI, FEE, FBE, PEE, and BLPE modes with internal FLL and PLL, enabling flexible clock sourcing from 31.25 kHz crystals up to 16 MHz external oscillators.

Peripherals include a 24-channel 12-bit ADC with 2.5 µs conversion time and internal bandgap reference (1.18–1.21 V), two analog comparators with stop-mode operation, and three Timer Pulse-Width Modulators (TPM1: 6-channel, TPM2: 2-channel, TPM3: 4-channel) supporting edge- and center-aligned PWM with coherency mechanisms for modulo and channel registers.

Key Specifications

FAQ

What is the maximum operating temperature range for the MC9S08DZ96CLH?

The MC9S08DZ96CLH is rated for operation from –40°C to +105°C ambient temperature, meeting automotive Grade 2 requirements. This specification is confirmed in Appendix A (Electrical Characteristics) of the MC9S08DZ128 Series Data Sheet Rev. 1, where all DC and AC parameters are characterized across this full range. The device uses silicon process and packaging qualified for under-hood automotive environments.

Does the MC9S08DZ96CLH support in-circuit programming via its background debug interface?

Yes, the MC9S08DZ96CLH supports full in-circuit programming and debugging through its single-wire background debug (BDM) interface. This interface enables flash erase/program, RAM access, breakpoint setting, and real-time bus capture without halting CPU execution. The BKGD/MS pin (Pin 4) serves as the dedicated BDM signal line, requiring only a compatible BDM pod or debugger such as the NXP DEMO9S08DZ60.

How many CAN message buffers does the MSCAN module in the MC9S08DZ96CLH provide?

The MSCAN module in the MC9S08DZ96CLH provides five dedicated receive buffers with FIFO storage capability. These buffers support flexible identifier acceptance filtering configured as either two 32-bit, four 16-bit, or eight 8-bit masks. Transmit functionality uses a single transmit buffer. This architecture is documented in Chapter 12 of the MC9S08DZ128 Series Data Sheet Rev. 1 and enables reliable reception of prioritized CAN traffic in automotive networks.

Can the MC9S08DZ96CLH operate from a 3.3 V supply instead of 5 V?

Yes, the MC9S08DZ96CLH operates over a supply voltage range of 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V systems. All I/O pins are 5 V tolerant regardless of VDD level, and internal regulators maintain consistent performance across this range. Electrical characteristics including ADC accuracy, clock stability, and CAN transceiver biasing remain valid at 3.3 V, as verified in Table A-6 (DC Characteristics) of the datasheet.

Is the MC9S08DZ96CLH pin-compatible with other members of the MC9S08DZ128 series?

Yes, the MC9S08DZ96CLH is pin-compatible with the MC9S08DZ128CLH in the 64-pin LQFP package. Both share identical pin assignments, electrical characteristics, and peripheral mapping per Table 2-1 (Page 34) and Section 2.1 of the MC9S08DZ128 Series Data Sheet Rev. 1. Differences are limited to on-die memory size (96 KB vs. 128 KB FLASH) and associated fuse settings - allowing shared PCB design and firmware portability with only linker script adjustments.
