NXP Semiconductors S9S08DV32F1MLH

Overview

S9S08DV32F1MLH 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 bus communication.

For engineers reviewing the S9S08DV32F1MLH datasheet, S9S08DV32F1MLH pinout, S9S08DV32F1MLH application, or S9S08DV32F1MLH equivalent, key selection criteria include its 20 MHz bus frequency, 53 GPIO pins with configurable slew rate and pull devices, MSCAN peripheral with five receive buffers and programmable identifier filters, and dual low-power stop modes with RTC wake-up capability.

Technical Context

The S9S08DV32F1MLH implements the HCS08 CPU core operating at up to 40 MHz CPU clock (20 MHz bus), supporting 32 interrupt/reset sources and the BGND instruction for single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with internal reference trimming and external crystal support from 1 MHz to 16 MHz.

On-chip peripherals include a 12-bit, 16-channel ADC with 2.5 μs conversion time and temperature sensor input; two analog comparators with bandgap reference option; and a full-featured MSCAN module compliant with ISO 11898-1, supporting standard/extended frames, remote frames, and FIFO-based receive buffering with flexible filter configuration.

FAQ

What is the maximum bus frequency supported by the S9S08DV32F1MLH?

The S9S08DV32F1MLH supports a maximum bus frequency of 20 MHz, derived from its 40 MHz CPU clock via a 2:1 divider. This frequency is sustained across the full operating voltage (2.7–5.5 V) and temperature (−40°C to +105°C) range, enabling deterministic timing for real-time control loops and CAN bit timing accuracy.

Does the S9S08DV32F1MLH include a built-in CAN controller?

Yes, the S9S08DV32F1MLH integrates a fully compliant Freescale Controller Area Network (MSCAN) module supporting CAN 2.0A and 2.0B protocols. It features five receive buffers with FIFO storage, programmable identifier acceptance filters, and support for standard/extended frames and remote frames - all implemented in hardware without CPU intervention.

What package type and pin count does the S9S08DV32F1MLH use?

The S9S08DV32F1MLH uses a 48-pin low-profile quad flat-pack (LQFP) package measuring 7×7 mm, with lead-free and RoHS-compliant construction. This package is explicitly listed for the MC9S08DV32 variant in Appendix C of the Rev 3 datasheet and matches the "MLH" suffix designation.

How much RAM is available on the S9S08DV32F1MLH?

The S9S08DV32F1MLH includes 2 KB of on-chip RAM, as confirmed by the memory map in Chapter 4 of the MC9S08DV60 Series Data Sheet Rev 3. While the family overview states "up to 3K", the DV32 variant is specifically allocated 2 KB - sufficient for stack, peripheral buffers, and real-time control variables in typical automotive and industrial applications.

Can the S9S08DV32F1MLH operate in low-power modes with RTC wake-up?

Yes, the S9S08DV32F1MLH supports two very low-power stop modes (Stop2 and Stop3) and a reduced-power wait mode. Its real-time counter (RTC) operates autonomously using an on-chip 1 kHz low-power oscillator, enabling precise wake-up intervals without external components - verified in Section 3.6 and Chapter 15 of the datasheet.
