NXP Semiconductors MC9S08DV60ACLH

Overview

MC9S08DV60ACLH from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 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 nodes requiring robust communication and low-power operation.

For engineers reviewing the MC9S08DV60ACLH datasheet, MC9S08DV60ACLH pinout, MC9S08DV60ACLH application, or MC9S08DV60ACLH equivalent, key selection factors include its 64-pin LQFP package, 20 MHz bus speed, MSCAN peripheral compliance, and support for Stop3/Stop2 low-power modes with RTC wake-up capability.

Technical Context

The MC9S08DV60ACLH implements the S08CPUV3 core with HC08 instruction set extension (including BGND), supporting up to 32 interrupt/reset sources and a 40-MHz CPU clock (20-MHz bus). Its Multi-Purpose Clock Generator (MCG) provides FLL- and PLL-based clock synthesis with internal reference trimming and external crystal/resonator support from 31.25 kHz to 16 MHz.

System-level protection includes COP watchdog with dual-clock source (1 kHz internal or bus clock), low-voltage detect with configurable trip points, illegal opcode/address detection, and flash block protection. Peripheral integration centers on MSCAN v1.0 (CAN 2.0A/B), two SCIs with LIN 2.0/SAE J2602 support, and a 16-channel 12-bit ADC with 2.5 μs conversion time and temperature sensor.

FAQ

What is the maximum bus frequency supported by the MC9S08DV60ACLH?

The MC9S08DV60ACLH supports a maximum bus frequency of 20 MHz, derived from its 40-MHz CPU clock via a 2:1 divider. This bus speed enables deterministic timing for real-time control loops, CAN message processing, and ADC sampling within strict cycle budgets. The MCG module allows configuration of multiple clock sources - including internal reference, FLL, and PLL - to maintain this bus frequency across voltage and temperature variations. MC9S08DV60ACLH achieves consistent performance without external clock conditioning circuitry.

Does the MC9S08DV60ACLH include a built-in temperature sensor?

Yes, the MC9S08DV60ACLH integrates a factory-calibrated on-die temperature sensor accessible through the 12-bit ADC's dedicated channel. This sensor operates across the full rated temperature range (–40°C to 85°C) and requires no external components. It delivers measurement accuracy within ±3°C over temperature and is commonly used for thermal monitoring in automotive ECUs and industrial controllers. The MC9S08DV60ACLH firmware can read this value directly via ADCSC1 register polling or interrupt-driven conversion.

Can the MC9S08DV60ACLH operate in low-power stop modes while maintaining CAN bus activity?

No - the MC9S08DV60ACLH disables the MSCAN module in Stop2 and Stop3 modes per its functional specification. However, it retains RTC operation using the 1 kHz internal oscillator to wake the MCU on timer expiry or external interrupt, after which CAN communication resumes. For continuous CAN listen-only operation during low-power states, external hardware (e.g., standby CAN transceiver with wake-on-CAN) is required. MC9S08DV60ACLH's design prioritizes ultra-low quiescent current (<10 μA in Stop3) over active peripheral retention.

What debug interface does the MC9S08DV60ACLH support?

The MC9S08DV60ACLH supports a single-wire background debug (BDM) interface via the BKGD/MS pin, enabling non-intrusive in-circuit debugging, flash programming, and real-time bus monitoring without halting CPU execution. This interface requires only one signal plus ground, eliminating the need for multi-pin JTAG connectors. Development tools such as P&E Micro's Multilink or SEGGER's J-Link with BDM firmware support full visibility into registers, memory, and peripheral states. MC9S08DV60ACLH does not support SWD or JTAG natively.

Is the MC9S08DV60ACLH pin-compatible with other members of the DV60 series?

Yes - the MC9S08DV60ACLH shares identical 64-pin LQFP pinout and electrical characteristics with all DV60-series variants (e.g., MC9S08DV48ACLH, MC9S08DV32ACLH) in the same package option. Differences are limited to flash size (60 KB vs. 48 KB vs. 32 KB), which affects memory-mapped features like bootloader space and EEPROM emulation capacity, but not pin assignment, peripheral register mapping, or I/O behavior. Firmware compiled for MC9S08DV60ACLH will run unmodified on lower-flash variants if memory usage stays within their limits.
