NXP Semiconductors MC9S08GB60CFUE

Overview

MC9S08GB60CFUE from NXP (formerly Freescale) is an 8-bit HCS08 microcontroller with 60 KB Flash, 4 KB RAM, and integrated peripherals including SCI, SPI, I²C, TPM, ATD, and KBI. It operates at up to 40 MHz bus frequency, supports multiple low-power stop/wait modes, and targets cost-sensitive embedded control in automotive body electronics and industrial sensors.

For engineers reviewing the MC9S08GB60CFUE datasheet, MC9S08GB60CFUE pinout, MC9S08GB60CFUE application, or MC9S08GB60CFUE equivalent, key selection criteria include its 48-pin QFN package, 32 MHz internal FLL capability, 10-bit 16-channel ADC, background debug interface (BDM), and Flash security features for firmware protection.

Technical Context

The MC9S08GB60CFUE implements the HCS08 CPU core with 5-cycle MOV instruction execution and a 16-bit index register (H:X). Its Internal Clock Generator (ICG) supports four clock modes - FEI, FBE, FEE, and SCM - enabling flexible clock source selection between internal RC, external crystal (32 kHz–4 MHz), or external clock input.

Peripherals are memory-mapped and share a unified 64 KB address space. The device integrates two SCI modules (SCI1/SCI2), one SPI, one I²C, two 16-bit TPM timers with PWM and input capture, a 10-bit ATD converter with hardware trigger support, and a keyboard interrupt module on Port A pins - all accessible via dedicated registers with bit-level control.

FAQ

What is the maximum bus frequency supported by the MC9S08GB60CFUE?

The MC9S08GB60CFUE supports a maximum bus frequency of 40 MHz when operating in FEE mode with an external 4 MHz crystal and FLL multiplication. This is confirmed in Section 7.3.5 and Table A-9 of the Rev. 2.3 datasheet, where electrical characteristics specify timing parameters up to 40 MHz bus speed under defined voltage and temperature conditions.

Does the MC9S08GB60CFUE include hardware support for I²C communication?

Yes, the MC9S08GB60CFUE integrates a full-featured I²C module (Section 13) supporting master and slave modes, 7-bit addressing, clock stretching, and arbitration. It is assigned to Port C pins PTC0 (SDA) and PTC1 (SCL), and its registers (IICC1–IICC2, IICxSR, IICxDAT) enable standard protocol compliance per I²C specification v2.1.

How many analog-to-digital converter (ATD) input channels does the MC9S08GB60CFUE provide?

The MC9S08GB60CFUE provides 16 analog input channels for its 10-bit ATD module, mapped to Port B pins PTB0–PTB7 and Port A pins PTA0–PTA7. This is explicitly listed in Section 14.1 and Table 2-2 of the datasheet, with full support for software and hardware triggering, scan mode, and 12 µs conversion time.

Is the MC9S08GB60CFUE compatible with the Freescale Background Debug Mode (BDM) interface?

Yes, the MC9S08GB60CFUE supports single-wire Background Debug Mode via the PTG0 pin (BKGD/MS), enabling non-intrusive debugging, flash programming, and real-time register inspection without halting system clocks. This is documented in Chapter 15 and Section 2.3.4 of the datasheet, with full toolchain support from P&E Micro and SEGGER.

What package type and pin count does the MC9S08GB60CFUE use?

The MC9S08GB60CFUE uses a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with wettable flank leads, as specified in Appendix B of the datasheet. Pin assignments are detailed in Section 2.2, and mechanical drawings confirm land pattern dimensions, thermal pad layout, and solder stencil recommendations for reliable assembly.
