Product details
Overview
MC9S08DV48MLF 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 - designed for automotive body electronics and industrial control where deterministic timing, bus communication, and low-power operation are critical.
For engineers reviewing the MC9S08DV48MLF datasheet, MC9S08DV48MLF pinout, MC9S08DV48MLF application, or MC9S08DV48MLF equivalent, key selection criteria include its 40-MHz CPU (20-MHz bus), 53 GPIO with configurable slew rate and hysteresis, dual SCI supporting LIN 2.0/SAE J2602, and MSCAN module with five receive buffers and programmable identifier filters.
Technical Context
The MC9S08DV48MLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and operating at 40 MHz CPU clock (20 MHz bus). Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based modes with internal reference trimming and external crystal support from 31.25 kHz to 16 MHz.
System-level protection includes COP watchdog with 1-kHz backup clock, low-voltage detect with reset/interrupt, illegal opcode/address detection, and flash block protection. Peripherals include a 12-bit, 16-channel ADC with 2.5 µs conversion time and temperature sensor, two analog comparators, and dual TPM modules (6-channel + 2-channel) supporting PWM, input capture, and output compare.

FAQ
What is the maximum operating frequency of the MC9S08DV48MLF CPU core?
The MC9S08DV48MLF features an HCS08 CPU core rated for up to 40 MHz operation, delivering a 20 MHz bus clock. This frequency enables deterministic real-time execution for automotive and industrial control tasks while maintaining low power consumption. All timing specifications in the official datasheet assume operation within the validated voltage and temperature ranges.
Does the MC9S08DV48MLF support CAN FD or only classical CAN?
The MC9S08DV48MLF implements the Freescale MSCAN module compliant with CAN 2.0A/B only - it does not support CAN FD. Its MSCAN peripheral handles standard and extended data frames, remote frames, and offers five receive buffers with programmable identifier filtering. For CAN FD requirements, newer NXP families such as S32K1 or S9S08DZ should be evaluated.
How much flash memory does the MC9S08DV48MLF have, and is it reprogrammable in-circuit?
The MC9S08DV48MLF contains 48 KB of on-chip flash memory that supports full read/program/erase operations over the entire specified operating voltage and temperature range. It is fully reprogrammable in-circuit via the single-wire background debug interface (BKGD/MS), enabling field firmware updates and development iteration without removing the device from the board.
What peripheral modules are included in the MC9S08DV48MLF for analog signal acquisition?
The MC9S08DV48MLF integrates a 12-bit, 16-channel SAR ADC with 2.5 µs conversion time, internal temperature sensor, and selectable internal bandgap reference. It also includes two analog comparators (ACMPx) with interrupt capability on rising/falling/both edges and option to compare against fixed internal reference voltage - providing comprehensive analog front-end capability for sensor interfacing.
Is the MC9S08DV48MLF pin-compatible with other members of the DV-series, such as the MC9S08DV60?
Yes, the MC9S08DV48MLF is pin-compatible with the MC9S08DV60CLF and MC9S08DV32MLF in the same 48-pin LQFP package variant. All share identical pin assignments, electrical characteristics, and peripheral register maps - allowing memory-size-based scalability without PCB redesign. However, the 64-pin and 32-pin LQFP variants are not interchangeable due to differing pin counts and layouts.
