Overview
MC9S08DV48ACLH from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB flash, 3 KB RAM, and integrated CAN 2.0A/B controller, ADC, and real-time counter - designed for automotive body electronics and industrial control nodes requiring robust communication and low-power operation.
For engineers reviewing the MC9S08DV48ACLH datasheet, MC9S08DV48ACLH pinout, MC9S08DV48ACLH application, or MC9S08DV48ACLH equivalent, this page delivers verified package mapping (48-pin LQFP), confirmed MSCAN/SCI/SPI/I²C peripheral support, clock generator (MCG) configuration options, and validated alternative MCU options for migration or second sourcing.
Technical Context
The MC9S08DV48ACLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with hardware debug via single-wire background interface and on-chip ICE. Its Multi-Purpose Clock Generator (MCG) supports FLL- and PLL-based modes with internal reference trimming and external crystal/resonator input (1–16 MHz).

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual-supply domains: digital (VDD/VSS) and analog (VDDAD/VSSAD) for noise isolation in mixed-signal operation |
| XTAL / EXTAL | Clock input terminals | Support crystal or ceramic resonator (1–16 MHz); XTAL connects to crystal leg, EXTAL to oscillator input |
| BKGD/MS | Background debug / mode select | Single-wire debug interface; pulled high during normal operation, driven low for background entry |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; triggers COP, LVD, or external assertion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DV48F1CLK | Same HCS08 core, 48 KB flash, 48-pin LQFP; differs in temperature grade (–40°C to +105°C vs. –40°C to +85°C) and internal oscillator trim calibration | Targeted for extended-temperature automotive under-hood use; higher qualification level (AEC-Q100 Grade 2) | Select S9S08DV48F1CLK when operating above +85°C ambient or requiring AEC-Q100 compliance. |
| MC9S08DZ48CLH | Same package and memory size but adds USB 2.0 interface and enhanced CAN features (e.g., loop-back self-test); uses different MCG architecture with improved jitter performance | Preferred where USB device connectivity or stricter CAN timing stability is required - e.g., diagnostic tools or gateway modules | Choose MC9S08DZ48CLH if USB host/device capability or tighter CAN bit-timing tolerance is mandatory. |
Compared with MC9S08DV48ACLH, S9S08DV48F1CLK offers extended temperature operation and automotive qualification at identical pinout and firmware compatibility, while MC9S08DZ48CLH trades CAN-only communication for USB integration and enhanced timing precision - making it suitable for hybrid interface applications where physical layer flexibility outweighs pure CAN optimization.

FAQ
What is the maximum operating frequency of the MC9S08DV48ACLH CPU core?
The MC9S08DV48ACLH CPU core operates at a maximum frequency of 40 MHz, with a corresponding bus clock of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is fully supported across the specified voltage (2.7–5.5 V) and temperature (–40°C to +85°C) ranges per the official datasheet Rev 3.
Does the MC9S08DV48ACLH support CAN FD or only classical CAN?
The MC9S08DV48ACLH supports only classical CAN per ISO 11898-1 (CAN 2.0A/B), not CAN FD. Its MSCAN module implements standard and extended identifier frames, remote frames, and five receive buffers with FIFO - but lacks the variable bit-rate arbitration and payload expansion required for CAN FD. For CAN FD, consider NXP's S32K1xx series or legacy MPC56xx derivatives.
How much RAM and flash memory does the MC9S08DV48ACLH provide?
The MC9S08DV48ACLH integrates 48 KB of on-chip flash memory and 3 KB of RAM. Flash supports read/program/erase over full operating voltage and temperature, with block protection and security features. RAM is used for variables, stack, and runtime data - sufficient for real-time control tasks with CAN, ADC, and timer peripherals active simultaneously.
What debug interface does the MC9S08DV48ACLH use, and how many pins are required?
The MC9S08DV48ACLH uses a single-wire background debug interface accessed via the BKGD/MS pin. Only one dedicated pin is required - no additional TCK/TMS/TDO/TDI signals - enabling in-circuit debugging and flash programming with minimal PCB footprint and simplified connector design compared to JTAG-based MCUs.
Is the MC9S08DV48ACLH pin-compatible with other members of the DV-series, such as MC9S08DV60 or MC9S08DV32?
No - the MC9S08DV48ACLH in 48-pin LQFP is not pin-compatible with MC9S08DV60 (64-pin LQFP) or MC9S08DV32 (32-pin LQFP). While they share the same HCS08 core, memory map, and peripheral register sets, package pin counts and assignments differ significantly. Migration requires PCB layout revision; however, firmware is largely source-code compatible within the DV-series family.
