Product details
Overview
MC9S08DZ16ACLF from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB flash, 2 KB EEPROM, and 4 KB RAM, operating at up to 40 MHz CPU / 20 MHz bus frequency. It integrates MSCAN (CAN 2.0A/B), dual SCI with LIN 2.0 support, 12-bit 24-channel ADC, two analog comparators, RTC, and six-channel TPM - designed for automotive body electronics and industrial control nodes requiring CAN connectivity and robust on-chip memory.
For engineers reviewing the MC9S08DZ16ACLF datasheet, MC9S08DZ16ACLF pinout, MC9S08DZ16ACLF application, or MC9S08DZ16ACLF equivalent, key selection criteria include CAN protocol compliance, in-circuit programmable EEPROM with sector erase, real-time interrupt capability in stop modes, and background debug interface compatibility with standard HCS08 toolchains.
Technical Context
The MC9S08DZ16ACLF implements the S08CPUV3 core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and featuring a multi-purpose clock generator (MCG) with FLL/PLL modes, internal reference trimming, and external crystal support from 31.25 kHz to 16 MHz. Its memory subsystem enables program/erase while executing flash and supports 8-byte single-page or 4-byte dual-page EEPROM erase sectors.
Peripherals are tightly coupled to low-power operation: two very low-power stop modes (Stop2/Stop3), RTC with 1 kHz internal oscillator for wake-up, and MSCAN with five receive buffers and flexible identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit). All 53 GPIO pins support configurable slew rate, drive strength, hysteresis, and pin-interrupt with selectable edge polarity.

FAQ
What is the maximum operating frequency of the MC9S08DZ16ACLF CPU core?
The MC9S08DZ16ACLF features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding 20 MHz bus clock frequency. This timing is validated across the full industrial temperature range (–40°C to +105°C) and supply voltage range (2.7 V to 5.5 V), enabling deterministic real-time performance in automotive and industrial environments where timing predictability is critical. The MC9S08DZ16ACLF achieves this via its multi-purpose clock generator (MCG) with PLL/FLL support and factory-trimmed internal reference.
Does the MC9S08DZ16ACLF support CAN 2.0B extended frames?
Yes, the MC9S08DZ16ACLF integrates the Freescale Controller Area Network (MSCAN) module compliant with CAN protocol Version 2.0A and 2.0B, including support for both standard (11-bit) and extended (29-bit) identifier frames. Its five receive buffers implement FIFO storage and accept programmable identifier filters - configured as 2×32-bit, 4×16-bit, or 8×8-bit masks - allowing flexible message prioritization and filtering in multi-node vehicle networks.
How much EEPROM does the MC9S08DZ16ACLF provide, and what are its erase characteristics?
The MC9S08DZ16ACLF includes 2 KB of on-chip EEPROM that is in-circuit programmable over full voltage and temperature ranges. It supports two erase granularities: 8-byte single-page erase and 4-byte dual-page erase. Erase operations can be aborted mid-sequence, and both program and erase functions operate concurrently with flash execution - enabling safe parameter storage and field updates without halting application code.
What debug interface does the MC9S08DZ16ACLF use, and is it compatible with standard tools?
The MC9S08DZ16ACLF uses a single-wire background debug (BDM) interface compliant with the HCS08 standard. It is fully compatible with NXP's S08 Cyclone Pro, Multilink Universal, and compatible third-party debug probes running P&E Micro or Segger J-Link firmware. This interface supports non-intrusive breakpoint setting, real-time register inspection, flash programming, and on-chip emulation - all through a single dedicated BKGD/MS pin.
Is the MC9S08DZ16ACLF qualified for automotive applications, and what temperature grade does it support?
Yes, the MC9S08DZ16ACLF is AEC-Q100 qualified for automotive applications and specified for operation across the extended temperature range of –40°C to +105°C. Its design includes system-level protections such as low-voltage detect with reset/interrupt, COP watchdog with backup 1-kHz clock source, illegal opcode/address detection, and flash block protection - meeting functional safety requirements for body electronics and chassis control modules.
