NXP Semiconductors MC9S08GT60ACBE

Overview

MC9S08GT60ACBE 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 capability. It targets cost-sensitive industrial control and automotive body electronics applications requiring deterministic real-time response.

For engineers reviewing the MC9S08GT60ACBE datasheet, MC9S08GT60ACBE pinout, MC9S08GT60ACBE application, or MC9S08GT60ACBE equivalent, key selection criteria include its QFN-48 package with exposed thermal pad, internal clock generator supporting FEE/FBE/FEI modes, low-voltage detect (LVD) with reset/interrupt options, and background debug mode (BDM) support for in-circuit development.

Technical Context

The MC9S08GT60ACBE implements the S08CPUV2 core with 16-bit index register, 8-bit accumulator, and condition code register. Its internal clock generator (S08ICGV2) supports multiple modes including FLL-engaged external (FEE) and bypassed external (FBE), enabling stable bus frequencies up to 20 MHz using external crystals from 32 kHz to 4 MHz or external clocks.

Peripheral integration includes two independent TPM modules (each with six channels), a 16-channel 10-bit ADC with configurable sample time and conversion triggers, and dual serial interfaces: one SCI (UART-compatible) and one IIC (standard-mode, 100 kHz). All peripherals are clocked from the same bus clock domain and support stop-mode wake-up via interrupt.

FAQ

What is the maximum bus frequency supported by the MC9S08GT60ACBE?

The MC9S08GT60ACBE supports a maximum bus frequency of 20 MHz. This is achieved in FEE (FLL Engaged External) mode using a 4 MHz crystal with 5× multiplication, or in FBE (FLL Bypassed External) mode with direct 20 MHz external clock input. The internal clock generator (S08ICGV2) ensures stable operation across voltage (2.7–5.5 V) and temperature (−40°C to 105°C) ranges specified in the datasheet.

Does the MC9S08GT60ACBE support in-circuit debugging?

Yes, the MC9S08GT60ACBE supports single-wire background debug mode (BDM) via the PTG0 pin. This allows full in-circuit programming, real-time register inspection, breakpoint setting, and memory read/write without halting peripheral operation. BDM is fully supported by CodeWarrior Development Studio and compatible third-party tools, and requires no additional pins beyond BKGD/MS.

What packaging variant is used for the MC9S08GT60ACBE?

The MC9S08GT60ACBE is supplied in a 48-pin QFN package with 7 × 7 mm body and exposed thermal pad, documented under package code 98ASA00466D. This copper-wire bonded variant supersedes earlier gold-wire versions per Freescale's QFN Addendum Rev. 0 (July 2014), offering improved wirebond reliability and thermal performance.

Can the MC9S08GT60ACBE operate from a 3.3 V supply?

Yes, the MC9S08GT60ACBE operates over a supply range of 2.7 V to 5.5 V, making it fully compatible with standard 3.3 V systems. All I/O pins are 5 V tolerant when configured as inputs, and internal peripherals-including the 10-bit ADC and TPM modules-function correctly at 3.3 V with appropriate reference voltage configuration (e.g., AVDD as VREFH).

How many ADC channels does the MC9S08GT60ACBE provide?

The MC9S08GT60ACBE integrates a 10-bit successive approximation ADC with 16 input channels. These are distributed across Port B (AD0–AD7) and Port C (AD8–AD15), with flexible software configuration for single-ended or differential acquisition, programmable sample time, and trigger sources including TPM overflow and software start.
