NXP Semiconductors MC9S08DN60ACLF

Overview

MC9S08DN60ACLF from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB on-chip Flash, 2 KB RAM, and 2 KB in-circuit programmable EEPROM. It features a 40-MHz CPU (20-MHz bus), 12-bit 16-channel ADC with temperature sensor, dual analog comparators, LIN-capable SCI, SPI, I²C, two TPM modules (6+2 channels), RTC, and real-time interrupt capability. Used in automotive body control modules and industrial sensor nodes requiring deterministic timing and low-power operation.

For engineers reviewing the MC9S08DN60ACLF datasheet, MC9S08DN60ACLF pinout, MC9S08DN60ACLF application, or MC9S08DN60ACLF equivalent, key selection criteria include Flash size (60 KB), 64-pin LQFP package, 12-bit ADC conversion time (2.5 μs), LIN 2.0/SAE J2602 support, and dual-stop mode power management for battery-operated systems.

Technical Context

The MC9S08DN60ACLF implements the HCS08 CPU core with HC08 instruction set plus BGND, supporting up to 32 interrupt/reset sources. Its Multi-Purpose Clock Generator (MCG) provides PLL and FLL modes with ±1.5% internal reference accuracy using factory-trimmed temperature-compensated IRC.

On-chip peripherals include a 12-bit ADC with automatic compare and bandgap reference, two analog comparators with edge-selectable interrupts, and a LIN-compliant SCI with master/slave extended break handling. The RTC operates from a 1-kHz internal oscillator or external crystal, enabling cyclic wake-up without external components.

FAQ

What is the maximum operating frequency of the MC9S08DN60ACLF CPU core?

The MC9S08DN60ACLF CPU core runs at a maximum frequency of 40 MHz, with a corresponding 20-MHz bus clock. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, supported by internal or external clock sources. The MC9S08DN60ACLF datasheet specifies this performance across the full industrial temperature range (-40°C to +85°C) and 4.5–5.5 V supply.

Does the MC9S08DN60ACLF support LIN communication natively?

Yes, the MC9S08DN60ACLF includes SCI1, a serial communications interface fully compliant with LIN 2.0 and SAE J2602 protocols. It supports master extended break generation and slave extended break detection, enabling direct integration into automotive LIN networks without external protocol translators. The MC9S08DN60ACLF implements all required timing tolerances and frame formatting in hardware.

What is the purpose of the RTCX1 and RTCX2 pins on the MC9S08DN60ACLF?

The RTCX1 and RTCX2 pins on the MC9S08DN60ACLF connect to a 32.768 kHz crystal to drive the on-chip real-time counter (RTC) oscillator. This dedicated low-frequency source allows the MC9S08DN60ACLF to maintain accurate timekeeping and generate wake-up interrupts even in Stop2 and Stop3 low-power modes - eliminating the need for external RTC ICs or main-system clock resources.

Can the MC9S08DN60ACLF perform ADC conversions while executing code from Flash memory?

Yes, the MC9S08DN60ACLF supports concurrent Flash execution and ADC operation. Its 12-bit ADC module can acquire samples and store results in RAM without halting CPU execution. Additionally, the MC9S08DN60ACLF allows Flash program/erase operations to occur while code runs from other Flash blocks - a capability confirmed in Section 4.5 of the Rev 3 datasheet.

Is the MC9S08DN60ACLF pin-compatible with other members of the MC9S08DNxx series?

No - the MC9S08DN60ACLF in 64-pin LQFP is not pin-compatible with lower-pin-count variants (e.g., 48-pin or 32-pin LQFP packages). While functional peripherals and register maps are consistent across the MC9S08DNxx family, pin assignments differ significantly between package options. Migration requires PCB layout revision; the MC9S08DN60ACLF datasheet explicitly lists distinct pinouts for each package variant in Chapter 2.
