NXP Semiconductors S9S08DV32F2MLH

Overview

S9S08DV32F2MLH from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip flash, 2 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 robust communication.

For engineers reviewing the S9S08DV32F2MLH datasheet, S9S08DV32F2MLH pinout, S9S08DV32F2MLH application, or S9S08DV32F2MLH equivalent, key selection criteria include CAN protocol compliance, 12-bit ADC conversion time (2.5 μs), MCG clock generator flexibility, low-power stop modes, and background debug interface support.

Technical Context

The S9S08DV32F2MLH implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), supporting 32 interrupt/reset sources and BGND instruction for single-wire debug. Its Multi-Purpose Clock Generator (MCG) provides FLL/PLL operation with internal reference trim and external crystal support (1–16 MHz).

On-chip peripherals include a 16-channel 12-bit ADC with temperature sensor and bandgap reference, two analog comparators, MSCAN module with five receive buffers and programmable identifier filters (2×32-bit, 4×16-bit, or 8×8-bit), and dual SCI interfaces compliant with LIN 2.0 and SAE J2602 protocols.

FAQ

What is the maximum operating frequency of the S9S08DV32F2MLH CPU core?

The S9S08DV32F2MLH 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 validated across the full industrial temperature range (–40°C to +105°C) per the MC9S08DV60 Series Data Sheet Rev 3.

Does the S9S08DV32F2MLH support CAN FD or only classical CAN?

The S9S08DV32F2MLH supports only classical CAN per ISO 11898-1:2003 (CAN 2.0A/B). It does not implement CAN FD features such as flexible data-rate or extended payload length. The MSCAN module is explicitly documented for standard and extended data frames, remote frames, and five receive buffers - all within classical CAN protocol boundaries.

How much RAM is available on the S9S08DV32F2MLH?

The S9S08DV32F2MLH integrates 2 KB of on-chip RAM. This value is specified in the "On-Chip Memory" section of the MC9S08DV60 Series Data Sheet Rev 3, which confirms 3 KB RAM for MC9S08DV60 but explicitly lists 2 KB for MC9S08DV32 variants - consistent with the part number's memory designation and verified against memory map tables in Chapter 4.

Is the S9S08DV32F2MLH pin-compatible with other DV-series MCUs like MC9S08DV48F2MLH?

Yes, the S9S08DV32F2MLH in the 48-pin LQFP package is pin-compatible with MC9S08DV48F2MLH and MC9S08DV16F2MLH. All share identical pin assignments, electrical characteristics, and peripheral mappings per the "Device Pin Assignment" section (Chapter 2) and mechanical drawings in Appendix C of the MC9S08DV60 Series Data Sheet Rev 3.

What debug interface does the S9S08DV32F2MLH use, and what hardware is required?

The S9S08DV32F2MLH uses a single-wire background debug (BDM) interface via the BKGD/MS pin. Debugging requires only a compatible BDM pod (e.g., PEMicro Cyclone or NXP DEMO9S08DV32) and standard 6-pin BDM header; no JTAG adapter or additional pins are needed. On-chip ICE enables real-time bus capture and non-intrusive breakpoints.
