NXP Semiconductors MC9S08GB60CFUER

Overview

MC9S08GB60CFUER 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 20 MHz bus frequency, supports multiple low-power stop/wait modes, and targets cost-sensitive industrial control and automotive body electronics.

For engineers reviewing the MC9S08GB60CFUER datasheet, MC9S08GB60CFUER pinout, MC9S08GB60CFUER application, or MC9S08GB60CFUER equivalent, key selection criteria include Flash endurance (100k erase/write cycles), on-chip ICG clock generation with FLL support, 5V-tolerant I/O capability, and background debug mode (BDM) interface compatibility.

Technical Context

The MC9S08GB60CFUER implements the HCS08 CPU core with 16-bit index register, 8-bit accumulator, and 16-bit stack pointer. Its internal clock generator (ICG) supports four operational modes-FEI, FBE, FEE, and SCM-with programmable FLL multiplication and external crystal or RC oscillator input.

Peripheral integration includes two serial communication interfaces (SCI1/SCI2), one SPI module, one I²C module, two 16-bit timer/PWM modules (TPM1/TPM2), a 10-bit 8-channel analog-to-digital converter (ATD), and keyboard interrupt (KBI) support on Port A pins-all mapped to dedicated I/O ports with configurable pull-ups and slew rate control.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MC9S08GB60CFUER?

The MC9S08GB60CFUER supports a maximum bus frequency of 20 MHz, achieved via its internal clock generator (ICG) with FLL engaged in FEE mode using a 4 MHz external crystal. This frequency governs instruction execution speed, peripheral timing resolution, and maximum baud rates for SCI/SPI/I²C interfaces. The HCS08 core executes most instructions in 1–5 bus cycles, making 20 MHz the practical upper limit for deterministic real-time response in control loops.

Does the MC9S08GB60CFUER support in-circuit debugging?

Yes, the MC9S08GB60CFUER supports single-wire background debug mode (BDM) via the PTG0 pin, enabling full read/write access to memory and registers, real-time breakpoints, and flash programming without halting system operation. This capability is implemented in silicon and does not require external debug hardware beyond a BDM interface adapter. The MC9S08GB60CFUER's BDM implementation complies with Freescale's standard protocol and is supported by CodeWarrior Development Studio v5.1+.

What analog features are integrated into the MC9S08GB60CFUER?

The MC9S08GB60CFUER integrates a 10-bit successive approximation analog-to-digital converter (ATD) with 8 input channels mapped to Port B pins (PTB0–PTB7), programmable sample time, software/hardware triggering, and conversion completion interrupts. It also includes an internal 1.25 V bandgap reference and supports external reference inputs. No DAC or analog comparators are included - the ATD is the sole analog acquisition peripheral.

Is the MC9S08GB60CFUER pin-compatible with other HCS08 devices?

No, the MC9S08GB60CFUER is not universally pin-compatible across the HCS08 family. While it shares the same 48-pin QFN footprint with MC9S08GT60CFUE, differences exist in peripheral mapping - for example, SCI2 signals appear on PTC0/PTC1 in MC9S08GB60CFUER but on different pins in GT-series variants. Pin compatibility must be verified per specific variant using Table 2-2 in the MC9S08GB/GT Data Sheet Rev. 2.3.

What packaging and RoHS status does the MC9S08GB60CFUER have?

The MC9S08GB60CFUER is supplied in a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad and is RoHS-compliant per EU Directive 2011/65/EU. The "E" suffix in the part number confirms lead-free termination and green molding compound. Full compliance documentation, including substance declarations and test reports, is available through NXP's official product change notifications and material declarations portal.
