NXP Semiconductors MC9S08DV32CLF

Overview

MC9S08DV32CLF from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 3 KB RAM, and integrated CAN 2.0A/B controller, ADC, and real-time counter-designed for automotive body electronics and industrial control systems requiring robust communication and low-power operation.

For engineers reviewing the MC9S08DV32CLF datasheet, MC9S08DV32CLF pinout, MC9S08DV32CLF application, or MC9S08DV32CLF equivalent, key selection criteria include its 40-MHz CPU (20-MHz bus), dual SCI with LIN 2.0 support, MSCAN module with five receive buffers and programmable identifier filters, and two very low-power stop modes with RTC wake-up capability.

Technical Context

The MC9S08DV32CLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL and PLL modes with factory-trimmed internal reference clock and ±1.5% FLL accuracy using temperature compensation.

Peripherals include a 16-channel 12-bit ADC (2.5 μs conversion), two analog comparators with bandgap reference option, TPM modules (6+2 channels), I²C (100 kbps), SPI, and a dedicated real-time counter with 1 kHz on-chip oscillator for cyclic wake-up without external components.

Key Specifications

Pinout & Package

MC9S08DV32CLF is housed in a 48-pin LQFP (7×7 mm) package with 53 general-purpose I/O pins and one input-only pin. All I/O pins support configurable pull devices, hysteresis, slew rate, and drive strength.

FAQ

What is the maximum bus frequency supported by the MC9S08DV32CLF?

The MC9S08DV32CLF supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a 2:1 divider. This bus speed is maintained across the full operating voltage (2.7–5.5 V) and temperature (–40°C to +105°C) range, enabling deterministic real-time performance in automotive environments where timing predictability is critical. The MC9S08DV32CLF achieves this using its Multi-Purpose Clock Generator (MCG) in FLL or PLL modes with factory-trimmed internal reference.

Does the MC9S08DV32CLF include hardware support for LIN communication?

Yes, the MC9S08DV32CLF includes two SCI modules that fully support LIN 2.0 Protocol and SAE J2602 compliance. Each SCI provides master extended break generation and slave extended break detection, enabling direct integration into LIN cluster networks without external protocol translators. This capability is implemented in silicon and documented in the MC9S08DV32CLF datasheet Section 14 (Serial Communications Interface), making LIN functionality available out-of-the-box for automotive body electronics applications.

How many CAN message buffers does the MC9S08DV32CLF provide, and how are they organized?

The MC9S08DV32CLF integrates the MSCAN module with five dedicated receive buffers organized in a FIFO structure. These buffers support flexible identifier acceptance filtering configured as either two 32-bit, four 16-bit, or eight 8-bit filters-allowing selective reception of standard or extended CAN frames without CPU intervention. This architecture is confirmed in the MC9S08DV32CLF datasheet Section 12 and reduces interrupt load in multi-node CAN networks typical in automotive and industrial control systems.

What power-saving features does the MC9S08DV32CLF offer for battery-powered applications?

The MC9S08DV32CLF provides two very low-power stop modes (Stop2 and Stop3), a reduced-power wait mode, and a very low-power real-time interrupt capable of waking the device from any mode-including stop-using its on-chip 1 kHz oscillator. This eliminates the need for external timing components while maintaining sub-microamp quiescent current, making the MC9S08DV32CLF suitable for long-life battery applications such as telematics nodes and wireless sensors where periodic wake-up and minimal energy consumption are essential.

Is the MC9S08DV32CLF pin-compatible with other members of the DV-series, such as the MC9S08DV60?

No, the MC9S08DV32CLF is not pin-compatible with the MC9S08DV60 or MC9S08DV48. While all DV-series devices share the same HCS08 core and peripheral architecture, they differ in package options (e.g., MC9S08DV32CLF uses 48-pin LQFP, MC9S08DV60 uses 64-pin LQFP) and pin assignments. Pin compatibility is explicitly absent per Freescale's MC9S08DV60 Series Data Sheet Rev 3, which lists each variant separately under "Package Options" and confirms distinct pinouts in Chapter 2 ("Pins and Connections").
