Product details
Overview
MC9S08DV48AMLH 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 systems requiring robust communication and low-power operation.
For engineers reviewing the MC9S08DV48AMLH datasheet, MC9S08DV48AMLH pinout, MC9S08DV48AMLH application, or MC9S08DV48AMLH equivalent, key selection criteria include its 48 KB flash capacity, MSCAN peripheral compliance with ISO 11898-1, 12-bit ADC with temperature sensor, and support for Stop3/Stop2 ultra-low-power modes in automotive-grade LQFP-48 packaging.
Technical Context
The MC9S08DV48AMLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND-based single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL/PLL modes with ±1.5% accuracy using internal temperature-compensated reference trimming stored in flash.
System-level protection includes COP watchdog with dual-clock source (1 kHz internal or bus clock), programmable low-voltage detect reset/interrupt, illegal opcode/address detection, and flash block protection - all meeting AEC-Q100 stress test requirements for automotive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9S08DZ48F1MLH | Successor part in S08DZ family; identical pinout, enhanced ESD rating (±8 kV HBM), updated MCG with faster PLL lock time | Same automotive body control use cases; supports newer production requirements including ISO/SAE 21434 cybersecurity readiness features | Select when new designs require extended lifecycle support beyond MC9S08DV series end-of-life schedule |

FAQ
What is the maximum operating frequency of the MC9S08DV48AMLH CPU core?
The MC9S08DV48AMLH CPU core operates at a maximum frequency of 40 MHz, with a corresponding bus clock speed of 20 MHz. This performance level is achieved through the HCS08 architecture's efficient instruction pipeline and supports real-time deterministic execution in automotive control loops. The MC9S08DV48AMLH maintains this timing across its full specified temperature range (–40°C to +125°C) when powered within the recommended 2.7–5.5 V supply range.
Does the MC9S08DV48AMLH support CAN FD or only classical CAN?
The MC9S08DV48AMLH supports only classical CAN protocol versions 2.0A and 2.0B, compliant with ISO 11898-1. It does not implement CAN FD features such as variable bit rates or extended data length. Its MSCAN module provides five receive buffers with FIFO storage and flexible identifier filtering, making it suitable for legacy and current-generation automotive networks where FD bandwidth is not required. For CAN FD applications, newer NXP S32K or SPC5 families should be considered instead of the MC9S08DV48AMLH.
How much user-accessible RAM does the MC9S08DV48AMLH provide?
The MC9S08DV48AMLH provides 3 KB of on-chip RAM, fully accessible for variables, stack operations, and data buffering. This RAM is retained during Stop2 and Stop3 low-power modes, enabling rapid wake-up with preserved context. The memory map allocates this RAM contiguously starting at address 0x0080, and it is independent of flash memory layout - ensuring deterministic access timing and no contention with program execution. All 3 KB are available to user firmware without reservation for system use.
Is the MC9S08DV48AMLH pin-compatible with other members of the DV series?
Yes, the MC9S08DV48AMLH is pin-compatible with MC9S08DV60AMLH, MC9S08DV32AMLH, and MC9S08DV16AMLH in the same 48-pin LQFP package variant. All share identical pin assignments, electrical characteristics, and peripheral mapping. Firmware written for one can run on another with only flash size and RAM configuration adjustments - enabling scalable design reuse across product tiers. However, pin compatibility does not extend to 32-pin or 64-pin DV-series packages, which have different I/O allocations.
What debug interface does the MC9S08DV48AMLH support?
The MC9S08DV48AMLH supports a single-wire background debug (BDM) interface via the BKGD/MS pin, compatible with standard Freescale/NXP BDM debuggers and IDEs like S32DS and CodeWarrior. This interface enables full non-intrusive debugging, flash programming, and real-time bus capture without requiring additional JTAG pins. The MC9S08DV48AMLH does not support SWD or JTAG; BDM remains the sole standardized debug path throughout the HCS08 DV series.
