NXP Semiconductors MC9S08DZ16ACLC

Overview

MC9S08DZ16ACLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller designed for automotive and industrial embedded control. It features a 40-MHz CPU (20-MHz bus), 16 KB on-chip Flash, 2 KB EEPROM, 4 KB RAM, and integrated CAN 2.0A/B controller, 12-bit ADC, and dual SCI/LIN interfaces - deployed in body control modules and sensor interface units requiring deterministic real-time response.

For engineers reviewing the MC9S08DZ16ACLC datasheet, MC9S08DZ16ACLC pinout, MC9S08DZ16ACLC application, or MC9S08DZ16ACLC equivalent, key selection criteria include CAN protocol compliance, Flash memory size, EEPROM endurance (100K erase/write cycles), real-time interrupt latency in Stop3 mode, and background debug interface compatibility with S08 BDM tools.

Technical Context

The MC9S08DZ16ACLC implements the HCS08 CPU core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and vectorized exception handling. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with factory-trimmed internal reference (±1.5% deviation over temperature) and external crystal support from 31.25 kHz to 16 MHz.

System-level protection includes COP watchdog with dual-clock source (1-kHz internal or bus clock), low-voltage detect with programmable trip points, illegal opcode/address detection, and Flash block protection. Peripheral integration centers on MSCAN with five receive buffers and flexible identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit), plus dual SCIs compliant with LIN 2.0 and SAE J2602.

Key Specifications

FAQ

What is the maximum operating frequency of the MC9S08DZ16ACLC CPU core?

The MC9S08DZ16ACLC features an HCS08 CPU core rated for up to 40 MHz operation, delivering a 20 MHz bus clock. This enables 50 ns instruction cycle timing for deterministic real-time control in automotive applications. The actual achievable frequency depends on supply voltage and temperature, with full specification guaranteed across the –40°C to 125°C automotive grade range per datasheet Appendix A.

Does the MC9S08DZ16ACLC support CAN FD or only classical CAN?

The MC9S08DZ16ACLC implements the Freescale MSCAN module compliant with CAN 2.0A/B specifications only - it supports standard and extended identifiers, remote frames, and bit rates up to 1 Mbps, but does not support CAN FD features such as flexible data-rate or extended payload length. For CAN FD, designers must select newer S32K or MPC57xx families.

How many bytes of EEPROM are available on the MC9S08DZ16ACLC, and what is its endurance rating?

The MC9S08DZ16ACLC integrates 2 KB (2048 bytes) of on-chip EEPROM, organized in erasable sectors of 8 bytes (single-page) or 4 bytes (dual-page). It is rated for a minimum of 100,000 erase/write cycles under specified operating conditions, with data retention exceeding 10 years at 85°C - validated per Freescale's characterization testing in the MC9S08DZ60 Series Data Sheet Rev. 4.

What debug interface does the MC9S08DZ16ACLC use, and is JTAG supported?

The MC9S08DZ16ACLC uses a single-wire background debug (BDM) interface via the BKGD/MS pin - not JTAG. This interface supports flash programming, real-time register inspection, and breakpoint debugging through Freescale/NXP BDM-compatible tools (e.g., P&E Multilink, OSJTAG). JTAG is not implemented; all development relies on the BDM protocol defined in the HCS08 Debug Interface User's Guide.

Is the MC9S08DZ16ACLC qualified to AEC-Q100, and which grade applies?

Yes, the MC9S08DZ16ACLC is qualified to AEC-Q100 Rev. D, Grade 2 (–40°C to +105°C ambient), as documented in Freescale's automotive qualification reports and product change notifications. While the 'C' suffix denotes commercial temperature range in some contexts, the 'ACLC' variant specifically carries full AEC-Q100 Grade 2 certification for under-hood and body-control applications.
