NXP Semiconductors MC9S08DN60MLF

Overview

MC9S08DN60MLF 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, operating at up to 40 MHz CPU / 20 MHz bus frequency. It integrates ADC (12-bit, 16-channel), dual analog comparators, SCI (LIN 2.0/J2602 compliant), SPI, I²C, two TPM modules (6+2 channels), RTC, and real-time interrupt capability - deployed in automotive body control modules and industrial sensor nodes.

For engineers reviewing the MC9S08DN60MLF datasheet, MC9S08DN60MLF pinout, MC9S08DN60MLF application, or MC9S08DN60MLF equivalent, key selection criteria include Flash size (60 KB), 64-pin LQFP package, 12-bit ADC conversion time (2.5 µs), LIN-capable SCI interface, and dual low-power stop modes with RTC wake-up support.

Technical Context

The MC9S08DN60MLF implements the S08CPUV3 core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and single-wire background debug. Its Multi-Purpose Clock Generator (MCG) provides FLL/PLL operation with ±1.5% accuracy using internal temperature-compensated reference and factory-trimmed internal clock.

Peripherals are tightly synchronized to the bus clock: ADC uses dedicated prescaler for stable 2.5 µs conversions; TPM modules support input capture, output compare, and edge-aligned PWM; RTC operates from either external 32.768 kHz crystal or internal 1 kHz oscillator for cyclic wake-up without external components.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S08DN60MLF CPU and bus?

The MC9S08DN60MLF features an HCS08 CPU core rated for up to 40 MHz operation, with a corresponding maximum bus clock frequency of 20 MHz. This timing is achieved using the on-chip Multi-Purpose Clock Generator (MCG) in PLL or FLL mode, and is validated across the full industrial temperature range (–40°C to +105°C) and supply voltage (4.5 V to 5.5 V). The MC9S08DN60MLF datasheet specifies these values in Section 8.1.1 and Appendix A.

Does the MC9S08DN60MLF support in-application programming (IAP) of Flash and EEPROM?

Yes, the MC9S08DN60MLF supports full in-application programming: Flash can be programmed and erased while code executes from other memory blocks, and EEPROM supports 8-byte single-page or 4-byte dual-page erase with abort capability. These functions are enabled via dedicated command sequences written to Flash and EEPROM control registers (FCCOB and FCNFG), and are documented in Chapter 4.5 of the MC9S08DN60MLF datasheet.

What communication interfaces does the MC9S08DN60MLF include?

The MC9S08DN60MLF integrates SCI (LIN 2.0 and SAE J2602 compliant), SPI (full-duplex or single-wire bidirectional), and I²C (up to 100 kbps, multi-master capable). It does not include CAN or USB. The SCI module supports master break generation and slave break detection, making it suitable for automotive sub-networks, while SPI and I²C serve sensor and display interfacing needs in industrial applications.

What is the ADC resolution and conversion speed of the MC9S08DN60MLF?

The MC9S08DN60MLF includes a 12-bit successive-approximation ADC with 16 input channels and a typical conversion time of 2.5 µs. It features automatic compare, temperature sensor input, and internal bandgap reference channel. Conversion speed is determined by ADC clock prescaler settings and bus frequency; minimum conversion time assumes optimal clock configuration and is specified in Table A-13 of the MC9S08DN60MLF datasheet.

Is the MC9S08DN60MLF pin-compatible with other members of the DN-series?

The MC9S08DN60MLF in the 64-pin LQFP package shares identical pinout and signal mapping with MC9S08DN48MLF, MC9S08DN32MLF, and MC9S08DN16MLF - enabling hardware reuse across memory variants. This compatibility is confirmed in Section 2.1 (Device Pin Assignment) of the MC9S08DN60MLF datasheet, which covers the full DN-series family and explicitly states shared pin definitions for the 64-pin variant.
