NXP Semiconductors MC9S08GB60ACFUE

Overview

MC9S08GB60ACFUE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB on-chip Flash, 4 KB RAM, and integrated peripherals including dual SCI, SPI, I²C, 16-channel 10-bit ADC, two 16-bit TPM modules, and keyboard interrupt support. It operates at up to 40 MHz bus frequency using internal or external clock sources and targets low-power industrial control and automotive body electronics.

For engineers reviewing the MC9S08GB60ACFUE datasheet, MC9S08GB60ACFUE pinout, MC9S08GB60ACFUE application, or MC9S08GB60ACFUE equivalent, key selection criteria include Flash endurance (100k erase/write cycles), QFN-48 package thermal performance, BDM debug interface compatibility, and LVD reset threshold tolerance across temperature.

Technical Context

The MC9S08GB60ACFUE implements the S08CPUV2 core with 16-bit index register, 8-bit accumulator, and 16-level hardware stack. Its Internal Clock Generator (S08ICGV2) supports FEI/FBE/FEE modes with FLL lock detection, enabling stable bus frequencies from 100 kHz to 40 MHz using crystal, resonator, or external clock inputs.

Peripheral integration includes two independent Serial Communication Interfaces (SCI1/SCI2) with LIN support, a master/slave SPI module, I²C-compatible serial interface, and two 16-bit Timer/PWM modules each with six channels-supporting input capture, output compare, and edge-aligned PWM generation with programmable prescalers and modulo counters.

FAQ

What is the maximum operating frequency of the MC9S08GB60ACFUE?

The MC9S08GB60ACFUE supports a maximum bus frequency of 40 MHz, achieved using the internal clock generator's FLL-engaged external clock (FEE) mode with a 10 MHz crystal input and 4× multiplication. This frequency defines instruction execution speed and peripheral timing resolution, and remains stable across the full −40°C to +105°C operating range when powered within 2.7–5.5 V.

Does the MC9S08GB60ACFUE support in-circuit debugging?

Yes, the MC9S08GB60ACFUE includes a single-wire Background Debug Mode (BDM) interface accessible via PTG0 pin. This allows full real-time debugging, flash programming, register inspection, and breakpoint setting without requiring additional debug hardware beyond a standard BDM pod. The interface remains functional in all non-halted modes including Wait and Stop3 with BDM enabled.

What package type and pin count does the MC9S08GB60ACFUE use?

The MC9S08GB60ACFUE uses a 48-pin QFN package (case outline 98ASA00466D), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package replaces earlier gold-wire variants with copper-wire bonding for improved reliability and is RoHS-compliant. Pin assignments match the MC9S08GBxxA series mechanical drawings in Appendix C of the Rev. 2 datasheet.

How many analog-to-digital converter channels does the MC9S08GB60ACFUE have?

The MC9S08GB60ACFUE integrates a 10-bit successive-approximation ADC with 16 input channels - eight dedicated analog inputs on Port B (AD0–AD7) and eight shared with Port A and Port F pins. Conversion time is 6.5 µs per sample at maximum bus frequency, and hardware triggers from TPM channels enable precise timing-synchronized sampling for motor control or sensor monitoring.

Is the MC9S08GB60ACFUE qualified for automotive applications?

Yes, the MC9S08GB60ACFUE is AEC-Q100 qualified for Grade 2 (−40°C to +105°C) operation and widely deployed in automotive body electronics such as door modules, seat controllers, and lighting systems. Its design includes voltage brown-out detection, EEPROM-like flash endurance, and robust ESD immunity (±4 kV HBM), meeting requirements for under-hood and cabin-mounted ECUs.
