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 |
|---|---|---|---|
| MC9S08DV60CLH | 60 KB flash, same pinout and peripheral set; higher memory headroom for complex CAN firmware stacks | Preferred where future firmware expansion or bootloader + application partitioning is required | Select when >48 KB flash is needed without changing PCB layout |
| S9S08DZ60F2MLC | NXP S08DZ family; 60 KB flash, enhanced CAN FD readiness, updated MCG with better jitter performance | Targeting next-gen automotive designs requiring CAN FD migration path and extended temperature range (–40°C to 125°C) | Choose for new designs needing longer product lifecycle and extended qualification |
Compared with MC9S08DV60CLH, the MC9S08DV48CLH trades 12 KB flash for cost-sensitive volume production, while retaining identical CAN, ADC, and debug capabilities; versus S9S08DZ60F2MLC, it lacks CAN FD support but offers proven field reliability and lower BOM cost in legacy 125 kbps CAN networks.

FAQ
What is the maximum operating frequency of the MC9S08DV48CLH CPU core?
The MC9S08DV48CLH features an HCS08 CPU core with a maximum core frequency of 40 MHz, delivering a 20 MHz bus speed. This enables deterministic execution of CAN protocol stacks and real-time control loops within tight timing budgets typical of automotive body electronics applications. The MC9S08DV48CLH achieves this performance across its full operating voltage range (2.7–5.5 V) and temperature range (–40°C to 105°C).
Does the MC9S08DV48CLH support CAN FD or only classical CAN?
The MC9S08DV48CLH supports only classical CAN (ISO 11898-1, CAN 2.0A/B) with standard and extended frame formats. It does not implement CAN FD features such as flexible data-rate or enhanced payload length. The MC9S08DV48CLH MSCAN module operates at up to 1 Mbps baud rate and includes five receive buffers with programmable identifier filters - sufficient for legacy automotive and industrial CAN networks.
What debug interface does the MC9S08DV48CLH provide?
The MC9S08DV48CLH provides a single-wire background debug (BKGD) interface compatible with Freescale/NXP BDM and OpenSDA tools. This interface supports full in-circuit emulation, flash programming, real-time bus capture, and breakpoint debugging using only the BKGD/MS pin - eliminating the need for JTAG headers or additional debug hardware in space-constrained designs.
How much RAM and flash memory does the MC9S08DV48CLH contain?
The MC9S08DV48CLH contains 48 KB of on-chip flash memory and 3 KB of RAM. Flash supports read/program/erase over full voltage and temperature ranges, with block protection and vector redirection. RAM is used for variables, stack, and heap operations, and remains accessible during wait and selected stop modes - enabling low-power sensor sampling with retained context.
Is the MC9S08DV48CLH pin-compatible with other devices in the DV-series?
Yes, the MC9S08DV48CLH in the 48-pin LQFP package shares identical pinout with MC9S08DV60CLH, MC9S08DV32CLH, and MC9S08DV16CLH. This allows hardware reuse across variants differing only in flash size (16 KB to 60 KB) and RAM allocation, simplifying platform design and enabling firmware scalability without PCB revision.
