Product details
Overview
MC9S08DV48CLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB on-chip flash, 3 KB RAM, and integrated CAN 2.0A/B controller, ADC, and real-time counter - used in automotive body control modules and industrial sensor nodes requiring deterministic timing and bus communication.
For engineers reviewing the MC9S08DV48CLC datasheet, MC9S08DV48CLC pinout, MC9S08DV48CLC application, or MC9S08DV48CLC equivalent, key selection criteria include flash size, CAN protocol compliance, 12-bit ADC resolution with temperature sensor, stop-mode power consumption, and LQFP-48 package compatibility with legacy HCS08 toolchains.
Technical Context
The MC9S08DV48CLC implements the S08CPUV3 core running at up to 40 MHz CPU/20 MHz bus frequency, with a Multi-Purpose Clock Generator (MCG) supporting FLL, PLL, and internal/external reference sources. Its memory subsystem includes flash with block protection and security features plus RAM with retention in low-power modes.
Peripheral integration centers on deterministic real-time operation: MSCAN supports five receive buffers with programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit), while the 16-channel 12-bit ADC achieves 2.5 μs conversion time with automatic compare and internal bandgap reference - both critical for closed-loop control in automotive ECUs.

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 |
|---|---|---|---|
| S9S08DZ48F1MLC | Successor part in S08DZ family; same 48 KB flash, but enhanced MCG with tighter FLL accuracy (±1.5% vs ±2%) and improved EMI performance | Designed for newer automotive platforms requiring AEC-Q100 Grade 2 qualification; lacks direct pin compatibility with MC9S08DV48CLC | Select when upgrading for long-term availability and stricter automotive qualification - requires PCB redesign due to different pin mapping |
| MC9S08DZ48CLC | Same package and pin count; adds EEPROM (2 KB), enhanced COP watchdog, and higher temperature grade (–40°C to 125°C vs –40°C to 105°C) | Targeted at under-hood applications with extended thermal requirements; retains functional overlap in CAN, ADC, and timer peripherals | Prefer for new designs needing EEPROM data logging or operation above 105°C - pin-compatible replacement with minor register initialization changes |
Compared with S9S08DZ48F1MLC and MC9S08DZ48CLC, the MC9S08DV48CLC offers proven field reliability in cost-sensitive body electronics, while its fixed 48 KB flash and LQFP-48 footprint simplify migration from earlier DV-series designs without requalification overhead.

FAQ
What is the maximum bus frequency supported by the MC9S08DV48CLC?
The MC9S08DV48CLC supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a configurable divider. This frequency is sustained across the full operating voltage (2.7–5.5 V) and temperature (–40°C to +105°C) range, enabling deterministic timing for CAN message handling and ADC sampling in automotive environments. The MCG module provides multiple clock source options including FLL and PLL to maintain stability under varying conditions.
Does the MC9S08DV48CLC include an integrated CAN transceiver?
No, the MC9S08DV48CLC integrates only the CAN protocol controller (MSCAN module), not the physical-layer transceiver. It requires an external CAN transceiver such as the MC33883 or TJA1042 connected to the CANTX and CANRX pins. This separation allows design flexibility in selecting transceivers optimized for specific EMC, fault tolerance, or sleep-mode current requirements - a standard architecture for HCS08 CAN microcontrollers.
How much RAM is available on the MC9S08DV48CLC, and is it retained in low-power modes?
The MC9S08DV48CLC includes up to 3 KB of on-chip RAM, with full retention supported in wait mode and Stop2 mode. In Stop3 mode, RAM retention depends on configuration - it can be enabled via the SPMSC2[RAMDIS] bit. This capability ensures state preservation during deep-sleep intervals, critical for applications like battery-powered sensor nodes that must resume operation instantly after wake-up without reloading variables from flash.
What ADC resolution and conversion speed does the MC9S08DV48CLC provide?
The MC9S08DV48CLC features a 12-bit successive-approximation ADC with 16 input channels and a minimum conversion time of 2.5 μs. It includes an internal temperature sensor and bandgap reference channel, supporting single-ended or differential measurements. The ADC operates independently of CPU activity and can trigger conversions via hardware signals (e.g., TPM overflow), making it suitable for time-critical sampling in motor control or environmental monitoring applications.
Is the MC9S08DV48CLC pin-compatible with other members of the DV-series?
Yes, the MC9S08DV48CLC in the 48-pin LQFP package shares identical pinout and electrical characteristics with the MC9S08DV60CLC, MC9S08DV32CLC, and MC9S08DV16CLC - differing only in flash size (60 KB, 48 KB, 32 KB, 16 KB). This enables hardware reuse across product variants, simplifying platform scaling and reducing PCB redesign effort when adjusting firmware complexity or feature set.
