NXP Semiconductors MC9S08DV48CLF

Overview

MC9S08DV48CLF 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 - used in automotive body control modules and industrial sensor nodes requiring deterministic timing and bus communication.

For engineers reviewing the MC9S08DV48CLF datasheet, MC9S08DV48CLF pinout, MC9S08DV48CLF application, or MC9S08DV48CLF equivalent, key selection criteria include flash size, CAN protocol support, 12-bit ADC conversion time, low-power stop modes, and LQFP-48 package compatibility with board-level thermal and routing constraints.

Technical Context

The MC9S08DV48CLF implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND debug instruction. Its Multi-Purpose Clock Generator (MCG) provides FLL/PLL modes with ±1.5% accuracy using internal temperature compensation and factory-trimmed reference clock.

On-chip peripherals include a 16-channel 12-bit ADC (2.5 μs conversion), two analog comparators with bandgap reference option, MSCAN module with five FIFO receive buffers and programmable acceptance filters (2×32-bit, 4×16-bit, or 8×8-bit), and dual SCI interfaces supporting LIN 2.0 and SAE J2602 protocols.

FAQ

What is the maximum operating frequency of the MC9S08DV48CLF CPU core?

The MC9S08DV48CLF CPU core operates at up to 40 MHz, with a corresponding 20 MHz bus frequency. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is fully supported across the device's rated temperature range of -40°C to +105°C. The MC9S08DV48CLF maintains deterministic instruction execution timing critical for real-time automotive control loops.

Does the MC9S08DV48CLF support CAN FD or only classical CAN?

The MC9S08DV48CLF supports only classical CAN (ISO 11898-1, CAN 2.0A/B) - not CAN FD. Its MSCAN module implements standard and extended data frames up to 1 Mbps, with five FIFO receive buffers and programmable acceptance filters. CAN FD features such as variable bit rates and extended data length are absent; users requiring CAN FD must select newer S32K or MPC57xx families instead of the MC9S08DV48CLF.

How much flash memory does the MC9S08DV48CLF have, and is it reprogrammable in-system?

The MC9S08DV48CLF contains 48 KB of on-chip flash memory that supports full read/program/erase operations over its entire operating voltage and temperature range. Reprogramming is performed in-system via the single-wire background debug interface without requiring external programming hardware. Flash block protection and security features prevent unauthorized access, and factory-trimmed calibration values are stored in reserved flash sectors for MCG reference clock accuracy.

What package type and pin count does the MC9S08DV48CLF use?

The MC9S08DV48CLF is packaged in a 48-pin low-profile quad flat-pack (LQFP) measuring 7×7 mm with 0.5 mm pitch. This RoHS-compliant, lead-free package supports standard surface-mount assembly processes and provides full access to all 53 GPIO pins (including one input-only pin), power, clock, reset, debug, and peripheral signals as defined in the Freescale MC9S08DV60 Series Data Sheet Rev 3.

Does the MC9S08DV48CLF include an integrated temperature sensor?

Yes, the MC9S08DV48CLF includes an integrated temperature sensor accessible through the 12-bit ADC module as channel AD15. It is factory-calibrated and referenced to the internal bandgap voltage, enabling direct Celsius-scale readings with typical accuracy of ±3°C over -40°C to +105°C. This sensor requires no external components and is commonly used for thermal monitoring in automotive and industrial applications where the MC9S08DV48CLF serves as the main system controller.
