Product details
Overview
MC9S08DZ48ACLF from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB on-chip 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, 24-channel 12-bit ADC, two analog comparators, dual TPM modules, RTC, I²C, SPI, and single-wire BDM debug - designed for automotive body electronics and industrial control nodes.
For engineers reviewing the MC9S08DZ48ACLF datasheet, MC9S08DZ48ACLF pinout, MC9S08DZ48ACLF application, or MC9S08DZ48ACLF equivalent, key selection criteria include CAN protocol compliance, in-circuit programmable EEPROM with sector erase, real-time interrupt capability in Stop3 mode, and factory-trimmed internal reference clock for stable timing without external crystal.
Technical Context
The MC9S08DZ48ACLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and a dedicated 1-kHz COP watchdog clock source. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based modes with ±1.5% FLL accuracy using internal temperature compensation and factory-stored trim values in Flash.
Peripherals are tightly coupled to low-power operation: MSCAN supports five receive buffers with FIFO and flexible identifier filtering (2×32-bit, 4×16-bit, or 8×8-bit); ADC delivers 2.5 μs conversion time with automatic compare, temperature sensor, and internal bandgap reference; RTC operates from external crystal or free-running 1-kHz on-chip oscillator for cyclic wake-up.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DZ48F1CLK | Same core, memory, and peripheral set; differs only in temperature grade (–40°C to +125°C vs. –40°C to +105°C for MC9S08DZ48ACLF) and packaging (48-pin QFN vs. LQFP) | Required for under-hood automotive applications exceeding +105°C ambient | Select S9S08DZ48F1CLK when extended temperature operation or QFN thermal performance is mandatory |
| MC9S08DZ60ACLF | Pin-compatible upgrade with 60 KB Flash (+12 KB), identical peripherals, package, and electrical specs | Preferred when firmware complexity or future OTA update requirements exceed 48 KB capacity | Choose MC9S08DZ60ACLF for headroom in code size without layout or driver changes |
Compared with S9S08DZ48F1CLK and MC9S08DZ60ACLF, the MC9S08DZ48ACLF offers optimal cost/performance balance for body electronics within its 105°C rating and 48 KB Flash constraint - enabling direct use of existing LQFP layouts and toolchains while meeting ASIL-B functional safety prerequisites via COP watchdog and LVD.

FAQ
What is the maximum operating frequency of the MC9S08DZ48ACLF CPU and bus?
The MC9S08DZ48ACLF features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus frequency of 20 MHz. This timing is validated across the full industrial temperature range (–40°C to +105°C) and supply voltage (4.5 V to 5.5 V), enabling deterministic real-time response for CAN message handling and PWM generation without overclocking risks.
Does the MC9S08DZ48ACLF support CAN FD or only classical CAN?
The MC9S08DZ48ACLF implements the MSCAN module compliant exclusively with ISO 11898-1 Classical CAN (2.0A/B), supporting standard and extended identifiers, remote frames, and five receive buffers. It does not support CAN FD features such as variable bit rates, larger payloads, or CRC enhancements - those require later-generation S32K or MPC5xxx families.
How much EEPROM is integrated into the MC9S08DZ48ACLF and what are its erase characteristics?
The MC9S08DZ48ACLF includes 2 KB of on-chip EEPROM, organized for in-circuit programming with 8-byte single-page or 4-byte dual-page erase sectors. Erase operations can be aborted mid-sequence, and both program and erase functions operate while Flash code execution continues - enabling safe data logging in automotive environments with power interruption tolerance.
What debug interface does the MC9S08DZ48ACLF provide and is external hardware required?
The MC9S08DZ48ACLF uses a single-wire Background Debug Mode (BDM) interface accessible via the BKGD/MS pin. Debugging and flash programming require an external BDM pod (e.g., P&E Multilink or OSJTAG), but no JTAG header or additional pins - simplifying PCB layout while supporting full on-chip emulation, real-time bus capture, and non-intrusive breakpoint debugging.
Is the internal temperature sensor in the MC9S08DZ48ACLF calibrated and how is it accessed?
Yes, the MC9S08DZ48ACLF includes a factory-calibrated on-die temperature sensor connected to a dedicated ADC channel. Calibration data is not stored in user-accessible registers, but the sensor provides ±5°C accuracy across –40°C to +125°C and is read by configuring ADCSC1 to select the internal sensor input - enabling thermal monitoring without external components.
