Product details
Overview
MC9S08DV16MLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB on-chip flash, 3 KB RAM, and integrated MSCAN, ADC, SPI, I²C, SCI, TPM, RTC, and analog comparators - designed for automotive body electronics and industrial control nodes requiring CAN connectivity and low-power operation.
For engineers reviewing the MC9S08DV16MLC datasheet, MC9S08DV16MLC pinout, MC9S08DV16MLC application, or MC9S08DV16MLC equivalent, key selection criteria include its 16 KB flash capacity, 53 GPIO + 1 input-only pin, dual SCI supporting LIN 2.0/SAE J2602, and MSCAN v2.0 A/B compliance in a 48-pin LQFP package.
Technical Context
The MC9S08DV16MLC implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with HC08 instruction set extension including BGND for background debug. It supports up to 32 interrupt/reset sources and features a Multi-Purpose Clock Generator (MCG) with FLL (±1.5% accuracy using internal temperature compensation) and PLL modes.
Its system protection includes COP watchdog with dual clock source options (1 kHz internal or bus clock), low-voltage detect with configurable trip points, illegal opcode/address detection, and flash block protection - all critical for automotive-grade reliability in harsh environments.

FAQ
What is the maximum operating frequency of the MC9S08DV16MLC CPU core?
The MC9S08DV16MLC 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 rated voltage and temperature range specified in the datasheet.
Does the MC9S08DV16MLC support CAN FD or only classical CAN?
The MC9S08DV16MLC supports only classical CAN (ISO 11898-1, CAN 2.0A/B) via its MSCAN module - not CAN FD. Its MSCAN implementation includes five receive buffers, programmable identifier filters, and full support for standard and extended frames, but lacks the bit-rate switching and payload expansion required for CAN FD.
How much SRAM does the MC9S08DV16MLC provide for runtime data storage?
The MC9S08DV16MLC integrates up to 3 KB of on-chip RAM for stack, heap, and variable storage. This SRAM is accessible at full bus speed and retains data during wait mode, though contents are lost in stop modes unless configured with specific retention settings - which are not supported by this variant.
Is the MC9S08DV16MLC pin-compatible with other members of the DV-series like MC9S08DV32 or MC9S08DV48?
Yes - the MC9S08DV16MLC shares identical pinout, package dimensions, and peripheral register mapping with MC9S08DV32MLC, MC9S08DV48MLC, and MC9S08DV60MLC in the same 48-pin LQFP package. Firmware developed for one can be reused across others with only flash size and RAM allocation adjustments.
What debug interface does the MC9S08DV16MLC use, and what hardware is required?
The MC9S08DV16MLC uses a single-wire background debug (BKGD) interface via the BKGD/MS pin. Debugging requires a compatible BDM pod (e.g., PE Micro Cyclone or NXP DEMO9S08DV16) and no additional pins - eliminating the need for SWD/JTAG headers and simplifying board layout for space-constrained automotive modules.
