NXP Semiconductors MC9S08GT60ACFBER

Overview

MC9S08GT60ACFBER from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller featuring 60 KB on-chip Flash, 4 KB RAM, and a 20 MHz bus frequency. It integrates a 10-bit ADC with 16 channels, two 16-bit Timer/PWM modules (TPM1/TPM2), SCI/IIC/SPI serial interfaces, and keyboard interrupt support. Designed for cost-sensitive industrial control and appliance applications requiring deterministic real-time response.

For engineers reviewing the MC9S08GT60ACFBER datasheet, MC9S08GT60ACFBER pinout, MC9S08GT60ACFBER application, or MC9S08GT60ACFBER equivalent, key selection criteria include QFN-48 package compatibility, 5V-tolerant I/O, internal clock generator with FLL, low-power stop modes, and background debug interface (BDM) support.

Technical Context

The MC9S08GT60ACFBER 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 including FEI (FLL Engaged Internal), FBE (FLL Bypassed External), and FEE (FLL Engaged External), enabling flexible clock sourcing from 32 kHz crystals up to 4 MHz external oscillators.

Peripheral integration includes two independent TPM modules each with six channels supporting input capture, output compare, and edge-aligned PWM; a 16-channel 10-bit ADC with programmable sample time and conversion trigger sources; and dual serial interfaces - one SCI (UART) and one IIC (I²C) - with configurable baud rates and interrupt-driven operation.

Key Specifications

FAQ

What is the maximum bus frequency supported by the MC9S08GT60ACFBER?

The MC9S08GT60ACFBER supports a maximum bus frequency of 20 MHz in FEE mode. When the high-gain oscillator (HGO) bit is cleared, the maximum frequency drops to 10 MHz in both FBE and FEE modes. This limitation ensures stable operation with lower-power external crystals or reduced EMI in noise-sensitive environments. The internal clock generator automatically adjusts based on configuration bits in the ICGC1 and ICGC2 registers.

Does the MC9S08GT60ACFBER support 5V-tolerant I/O pins?

Yes, the MC9S08GT60ACFBER features 5V-tolerant GPIO pins across all ports (PTA–PTG), allowing direct interfacing with 5V logic, sensors, and actuators while operating from a 2.7–5.5V supply. This eliminates level-shifting components in mixed-voltage systems. Tolerance is specified per IEC 61000-4-2 and verified across temperature and voltage ranges in the device's electrical characteristics table (Appendix A).

How many ADC channels does the MC9S08GT60ACFBER have, and what is its resolution?

The MC9S08GT60ACFBER includes a single 10-bit successive approximation ADC with 16 input channels (AD0–AD15), mapped across Port B and Port C pins. It supports software-triggered and hardware-triggered conversions, programmable sample time, and selectable reference voltages (VDD or internal 1.25V bandgap). Conversion time is 12 bus cycles minimum, enabling up to ~167 kSPS at 20 MHz bus speed.

What debug interface does the MC9S08GT60ACFBER use, and how is it implemented?

The MC9S08GT60ACFBER uses a single-wire Background Debug Mode (BDM) interface via the PTG0 pin, supporting full-speed debugging, flash programming, and real-time register inspection without halting CPU execution. It operates at up to 1 Mbps and requires only one physical connection plus ground. No external debug probe is needed beyond a BDM-capable programmer such as the OSBDM or PE Micro Cyclone MAX.

Is the MC9S08GT60ACFBER pin-compatible with other members of the GTxxA series?

Yes, the MC9S08GT60ACFBER shares identical pinout and package (48-pin QFN, 98ASA00466D) with MC9S08GT32ACFBER and MC9S08GT16ACFBER. Firmware and hardware designs can scale across these variants by adjusting Flash/RAM usage and peripheral enable settings - enabling common PCB layouts for multiple product SKUs with different memory configurations.
