NXP Semiconductors MC9S08DV32CLC

Overview

MC9S08DV32CLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB on-chip 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 deterministic timing and robust communication.

For engineers reviewing the MC9S08DV32CLC datasheet, MC9S08DV32CLC pinout, MC9S08DV32CLC application, or MC9S08DV32CLC equivalent, key selection criteria include CAN protocol support, 12-bit ADC conversion time (2.5 μs), 40-MHz CPU clock, low-power stop modes, and LQFP-48 package compatibility with automotive-grade temperature range (–40°C to +85°C).

Technical Context

The MC9S08DV32CLC implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources and operating at 40 MHz CPU / 20 MHz bus frequency. Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with internal reference trimming 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, dual SCI modules supporting LIN 2.0/SAE J2602, SPI, I²C, two TPM timers (6- and 2-channel), and an 8-bit real-time counter with 1-kHz internal oscillator for wake-up scheduling.

Key Specifications

FAQ

What is the maximum bus frequency supported by the MC9S08DV32CLC?

The MC9S08DV32CLC supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via a 2:1 divider. This timing is validated across the full operating voltage (4.5–5.25 V) and temperature (–40°C to +85°C) range per Freescale MC9S08DV60 Rev 3 datasheet, Table A-6. The bus clock drives all peripheral modules including ADC, TPM, and MSCAN, ensuring deterministic timing for real-time control loops.

Does the MC9S08DV32CLC include an integrated CAN controller?

Yes, the MC9S08DV32CLC 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, flexible identifier filtering (configurable as 2×32-bit, 4×16-bit, or 8×8-bit), and support for standard/extended frames and remote frames - all documented in Chapter 12 of the MC9S08DV60 Series Data Sheet Rev 3.

What package type and pin count does the MC9S08DV32CLC use?

The MC9S08DV32CLC uses a 48-pin low-profile quad flat-pack (LQFP) package measuring 7×7 mm with 0.5 mm pitch, as specified in Appendix C of the MC9S08DV60 Series Data Sheet Rev 3. This package is identical to that used by MC9S08DV48CLC and MC9S08DV16CLC, enabling footprint reuse across the DV-series for scalable memory variants.

Can the MC9S08DV32CLC operate in low-power modes with RTC wake-up capability?

Yes, the MC9S08DV32CLC supports two very low-power stop modes (Stop2 and Stop3) and a reduced-power wait mode. Its real-time counter (RTC) can run from a dedicated 1-kHz internal oscillator during Stop modes, enabling cyclic wake-up without external components - a feature confirmed in Section 3.6 and Chapter 15 of the MC9S08DV60 Series Data Sheet Rev 3.

Is the MC9S08DV32CLC pin-compatible with other members of the DV-series?

Yes, the MC9S08DV32CLC shares identical pinout and package dimensions with MC9S08DV48CLC and MC9S08DV16CLC in the 48-pin LQFP variant. All three devices use the same peripheral register mapping and memory layout, allowing hardware design reuse and software scalability across flash size options - as verified in Section 2.1 and Chapter 1 of the MC9S08DV60 Series Data Sheet Rev 3.
