NXP Semiconductors MC9S08DV48ACLC

Overview

MC9S08DV48ACLC from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 48 KB flash, 3 KB RAM, and integrated CAN 2.0A/B controller, ADC, SPI, I²C, SCI/LIN, TPM, RTC, and analog comparators - designed for automotive body electronics and industrial control systems requiring robust real-time communication and mixed-signal processing.

For engineers reviewing the MC9S08DV48ACLC datasheet, MC9S08DV48ACLC pinout, MC9S08DV48ACLC application, or MC9S08DV48ACLC equivalent, key selection criteria include its 48 KB flash size, 53 GPIO with configurable slew rate and pull devices, dual SCI supporting LIN 2.0/SAE J2602, MSCAN with five receive buffers and programmable identifier filters, and support for two low-power stop modes with RTC wake-up capability.

Technical Context

The MC9S08DV48ACLC implements the HCS08 CPU core running at up to 40 MHz (20 MHz bus), with HC08 instruction set plus BGND, and supports up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides PLL and FLL modes with internal reference clock trim adjustment stored in flash.

On-chip peripherals include a 12-bit, 16-channel ADC with 2.5 μs conversion time and temperature sensor; two analog comparators with edge-selectable interrupts; one 6-channel and one 2-channel TPM; and a real-time counter with external clock input and free-running 1 kHz oscillator for cyclic wake-up.

FAQ

What is the maximum bus frequency supported by the MC9S08DV48ACLC?

The MC9S08DV48ACLC supports a maximum bus frequency of 20 MHz, derived from its 40-MHz HCS08 CPU core via an internal divide-by-2 mechanism. This bus speed ensures deterministic timing for peripheral modules including MSCAN, TPM, and ADC, and is validated across the full operating voltage (2.7–5.5 V) and temperature (–40°C to +85°C) range specified for the MC9S08DV48ACLC.

Does the MC9S08DV48ACLC include a hardware CAN controller?

Yes, the MC9S08DV48ACLC integrates the Freescale Controller Area Network (MSCAN) module compliant with ISO 11898-1 (CAN 2.0A/B). It supports standard and extended data frames, remote frames, five receive buffers with FIFO behavior, and flexible identifier filtering configurations - all implemented in hardware without CPU intervention during message reception.

What package type and pin count does the MC9S08DV48ACLC use?

The MC9S08DV48ACLC uses a 48-pin low-profile quad flat-pack (LQFP) package measuring 7×7 mm. This package is explicitly listed in the MC9S08DV60 Series Data Sheet Rev 3 as a supported option for the MC9S08DV48 variant and includes dedicated pins for power, ground, crystal, reset, debug interface, ADC reference, and multiplexed peripheral I/O.

Can the MC9S08DV48ACLC operate in low-power modes with RTC wake-up capability?

Yes, the MC9S08DV48ACLC supports two very low-power stop modes (Stop2 and Stop3) and a reduced-power wait mode. Its real-time counter (RTC) can generate wake-up events from any of these modes using either an external clock source or its free-running on-chip 1-kHz oscillator - enabling battery-powered operation with periodic sensor polling or communication scheduling without external timing components.

Is the MC9S08DV48ACLC pin-compatible with other members of the DV-series?

No, the MC9S08DV48ACLC is not universally pin-compatible across the DV-series. While the 48-pin LQFP variant shares the same package footprint with MC9S08DV48 variants, it differs from 64-pin (e.g., MC9S08DV60) and 32-pin (e.g., MC9S08DV16) versions in pin count and signal mapping. Pin compatibility must be verified per specific part number and package using the "Device Pin Assignment" section in the official MC9S08DV60 Series Data Sheet Rev 3.
