NXP Semiconductors MC9S08DV32AMLF

Overview

MC9S08DV32AMLF from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 3 KB RAM, 53 GPIO pins, and integrated MSCAN, ADC12, TPM, SCI, SPI, IIC, RTC, and ACMP peripherals. It operates at up to 40 MHz CPU / 20 MHz bus frequency and supports CAN 2.0A/B in automotive body control modules.

For engineers reviewing the MC9S08DV32AMLF datasheet, MC9S08DV32AMLF pinout, MC9S08DV32AMLF application, or MC9S08DV32AMLF equivalent, key selection criteria include on-chip CAN controller compliance, 12-bit ADC conversion time (2.5 μs), real-time interrupt capability in stop modes, and single-wire background debug interface support.

Technical Context

The MC9S08DV32AMLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides FLL and PLL modes with internal reference clock trim stored in flash and ±1.5% FLL accuracy using factory temperature compensation.

On-chip system protection includes COP watchdog with dual clock source (1 kHz internal or bus clock), low-voltage detect with configurable trip points, illegal opcode/address detection, and flash block protection. Peripherals are fully functional in Run, Wait, and Stop3 modes, with RTC enabled by free-running 1 kHz oscillator for cyclic wake-up.

FAQ

What is the maximum operating frequency of the MC9S08DV32AMLF CPU core?

The MC9S08DV32AMLF CPU core operates at a maximum frequency of 40 MHz, with a corresponding bus clock of 20 MHz. This performance level is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode. The MC9S08DV32AMLF maintains full functionality across its specified voltage (2.7–5.5 V) and temperature (−40°C to +105°C) ranges at this speed, as verified in Freescale Document MC9S08DV60 Rev 3, Section 8.4.1.

Does the MC9S08DV32AMLF support CAN FD or only classical CAN?

The MC9S08DV32AMLF supports only Classical CAN (ISO 11898-1, CAN 2.0A/B) and does not implement CAN FD features such as variable bit rate or extended data length. Its MSCAN module complies strictly with CAN 2.0B specification, including support for standard and extended identifiers, remote frames, and five receive buffers with FIFO storage. This is explicitly confirmed in Section 12 of the MC9S08DV60 Series Data Sheet Rev 3.

How much RAM and flash memory does the MC9S08DV32AMLF include?

The MC9S08DV32AMLF integrates 32 KB of on-chip flash memory and up to 3 KB of RAM. Flash supports read/program/erase operations across the full operating voltage (2.7–5.5 V) and temperature (−40°C to +105°C) range, with block protection and security features. RAM is volatile and mapped into the HCS08 linear address space starting at 0x0080, as defined in Chapter 4 of the MC9S08DV60 Series Data Sheet Rev 3.

What debug interface does the MC9S08DV32AMLF use, and how many pins are required?

The MC9S08DV32AMLF uses a single-wire background debug (BDM) interface accessed via the BKGD/MS pin, requiring only one dedicated signal plus ground. No additional debug clock or data lines are needed. This interface supports full in-circuit emulation, real-time bus capture, and flash programming. The implementation conforms to Freescale's HCS08 BDM specification and is documented in Chapter 17 of the MC9S08DV60 Series Data Sheet Rev 3.

Is the MC9S08DV32AMLF qualified for automotive applications, and what temperature grade does it support?

Yes, the MC9S08DV32AMLF is AEC-Q100 qualified for automotive applications and rated for operation from −40°C to +105°C. It meets stress test requirements for temperature cycling, humidity, and ESD per AEC-Q100 Rev G. The "M" in the part number denotes the extended temperature grade, and the "LF" suffix indicates lead-free 64-pin LQFP packaging - both consistent with automotive production standards outlined in Freescale's ordering information appendix (Section C, MC9S08DV60 Series Data Sheet Rev 3).
