NXP Semiconductors MC9S08GB60ACFUER

Overview

MC9S08GB60ACFUER 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, and two 16-bit TPM timer/PWM modules. It operates at up to 40 MHz bus frequency using internal or external clock sources and targets cost-sensitive industrial control and automotive body electronics applications.

For engineers reviewing the MC9S08GB60ACFUER datasheet, MC9S08GB60ACFUER pinout, MC9S08GB60ACFUER application, or MC9S08GB60ACFUER equivalent, key selection criteria include its QFN-48 package, 5 V tolerant I/O, low-power stop modes (Stop3 current < 1 µA), and compatibility with S08 background debug mode for in-circuit programming and debugging.

Technical Context

The MC9S08GB60ACFUER implements the S08CPUV2 core with 16-bit index register, 8-bit accumulator, and 16-level hardware stack. Its internal clock generator (S08ICGV2) supports multiple modes - FEI, FEE, FBE - enabling flexible clocking from 32 kHz crystals to 4 MHz external oscillators, with bus frequencies scalable up to 40 MHz via FLL multiplication.

Peripheral integration includes two serial communication interfaces (SCI1/SCI2), one I²C module (S08IICV1), one SPI controller (S08SPIV3), a 16-channel 10-bit analog-to-digital converter (S08ATDV3), and dual 16-bit timer/PWM modules (TPM1/TPM2) with input capture, output compare, and edge-aligned PWM capabilities - all accessible through dedicated port pins mapped in the 48-pin QFN package.

FAQ

What is the maximum operating frequency of the MC9S08GB60ACFUER?

The MC9S08GB60ACFUER supports a maximum bus frequency of 40 MHz, achieved using the internal FLL in FEE mode with an external 4 MHz crystal. This frequency governs instruction execution speed, peripheral timing resolution, and ADC conversion rate - all verified in the Rev. 2 datasheet's electrical characteristics (Appendix A). The MC9S08GB60ACFUER maintains full functionality across its specified voltage and temperature range at this speed.

Does the MC9S08GB60ACFUER support in-circuit debugging without additional hardware?

Yes, the MC9S08GB60ACFUER integrates Background Debug Mode (BDM) accessible via the PTG0 pin, enabling full in-circuit debugging - including flash programming, breakpoint setting, and register inspection - using only a single-wire connection and standard BDM interface tools. No JTAG header, debug probe, or external debug circuitry is required, as confirmed in Chapter 15 of the MC9S08GB60ACFUER datasheet.

What package type and dimensions does the MC9S08GB60ACFUER use?

The MC9S08GB60ACFUER uses a 48-pin QFN package (document number 98ASA00466D), measuring 7 mm × 7 mm × 0.85 mm with an exposed thermal pad. It employs copper wire bonding and complies with RoHS requirements. This package replaces earlier gold-wire variants and is documented in the QFN_Addendum Rev. 0 (July 2014) as part of Freescale's QFN migration program.

Can the MC9S08GB60ACFUER operate from a 32 kHz watch crystal?

Yes, the MC9S08GB60ACFUER supports 32 kHz crystal operation on EXTAL/XTAL pins for low-power real-time clock functions and Stop mode wake-up. In FEI mode, it can generate a 1–4 MHz bus clock from the 32 kHz source using internal FLL multiplication - enabling accurate timekeeping while maintaining system responsiveness, as detailed in Section 7.4.2 of the MC9S08GB60ACFUER datasheet.

How many analog input channels does the MC9S08GB60ACFUER ADC support?

The MC9S08GB60ACFUER integrates a 10-bit successive approximation ADC with 16 input channels - eight dedicated analog inputs (AD0–AD7) on Port B, and eight additional channels accessible via multiplexed pins on Ports A, C, and E. Channel selection, sample time, and conversion triggers are fully software-configurable per the S08ATDV3 module description in Chapter 14 of the MC9S08GB60ACFUER datasheet.
