Product details
Overview
MC9S08DZ48ACLH from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB on-chip flash, 4 KB RAM, and integrated CAN 2.0A/B controller, designed for automotive body electronics and industrial control systems requiring robust real-time communication and low-power operation.
For engineers reviewing the MC9S08DZ48ACLH datasheet, MC9S08DZ48ACLH pinout, MC9S08DZ48ACLH application, or MC9S08DZ48ACLH equivalent, key selection criteria include its 48 KB flash size, dual SCI with LIN 2.0 support, 24-channel 12-bit ADC, and 53 GPIO pins in a 48-pin LQFP package - all confirmed in Rev. 4 (June 2008) datasheet coverage of the DZ-series family.
Technical Context
The MC9S08DZ48ACLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and featuring a Multi-Purpose Clock Generator (MCG) with FLL and PLL modes, factory-trimmed internal reference clock, and loss-of-lock protection. Its memory subsystem includes flash programmable/erasable over full voltage/temperature range and up to 2 KB EEPROM with 4-byte dual-page erase capability.
Peripherals include MSCAN compliant with CAN 2.0A/B, two SCIs supporting LIN 2.0 and SAE J2602, SPI, I²C, two analog comparators, RTC, and dual TPM modules (6-channel + 2-channel). All I/O pins feature configurable slew rate, drive strength, hysteresis, and pull devices - critical for noise-immune automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DZ48F1CLK | Same core, flash, and peripheral set; differs only in temperature grade (–40°C to +105°C vs. –40°C to +85°C for MC9S08DZ48ACLH) and packaging (lead-free LQFP vs. legacy leaded) | Required for under-hood automotive use where extended temperature operation is mandated | Select S9S08DZ48F1CLK when operating ambient exceeds 85°C or RoHS compliance is mandatory beyond JEDEC Level 3 |
| MC9S08DZ60ACLH | Identical package, pinout, and peripheral complement; differs only in flash capacity (60 KB vs. 48 KB) and EEPROM size (2 KB vs. 2 KB) | Preferred when firmware growth headroom or larger calibration tables are needed without changing PCB layout | Choose MC9S08DZ60ACLH if future firmware updates or enhanced diagnostics require >48 KB code space |
Compared with S9S08DZ48F1CLK and MC9S08DZ60ACLH, the MC9S08DZ48ACLH offers optimal balance of cost, code density, and thermal margin for cabin-mounted automotive modules and industrial controllers operating within commercial temperature ranges.

FAQ
What is the maximum operating frequency of the MC9S08DZ48ACLH CPU core?
The MC9S08DZ48ACLH features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding 20 MHz bus frequency. This timing is validated across the full specified voltage and temperature range per the Rev. 4 datasheet. The actual achievable bus speed depends on the selected clock source (e.g., crystal, internal reference) and MCG configuration mode - PLL or FLL - and must be verified against electrical characteristics in Appendix A.
Does the MC9S08DZ48ACLH support CAN FD or only classical CAN?
The MC9S08DZ48ACLH implements the MSCAN module compliant exclusively with CAN 2.0A and 2.0B protocols, supporting standard and extended identifiers, remote frames, and five receive buffers with FIFO. It does not support CAN FD features such as higher bit rates, flexible data length, or CRC enhancements. For CAN FD functionality, designers must select newer NXP S32K or Kinetis families.
How much EEPROM is integrated into the MC9S08DZ48ACLH?
The MC9S08DZ48ACLH integrates up to 2 KB of in-circuit programmable EEPROM, organized in sectors supporting 8-byte single-page or 4-byte dual-page erase operations. This EEPROM retains data during power loss and supports program-and-erase while executing flash code - enabling reliable storage of calibration data, configuration parameters, or event logs without halting MCU operation.
What debug interface does the MC9S08DZ48ACLH provide?
The MC9S08DZ48ACLH provides a single-wire background debug mode (BDM) interface via the BKGD/MS pin, enabling non-intrusive programming, real-time emulation, and breakpoint debugging without requiring dedicated debug pins or halting CPU execution. This interface is fully supported by P&E Micro and SEGGER tools and is documented in Chapter 17 of the MC9S08DZ60 Series Data Sheet Rev. 4.
Is the MC9S08DZ48ACLH pin-compatible with other members of the DZ-series?
Yes - the MC9S08DZ48ACLH shares identical pinout and package (48-pin LQFP) with MC9S08DZ60ACLH, MC9S08DZ32ACLH, and MC9S08DZ16ACLH. This allows hardware reuse across firmware variants differing only in flash/RAM size. However, pin compatibility does not imply functional equivalence: peripherals enabled and memory maps differ per variant, requiring firmware adaptation even when PCB layout remains unchanged.
