Product details
Overview
MC9S08GT16AMFBE from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 16 KB Flash, 2 KB RAM, 40-MHz CPU, 10-bit 8-channel ADC, dual SCI, SPI, I²C, and dual TPM timer/PWM modules. It operates from 1.8–3.6 V and targets low-power industrial control and sensor interface applications.
For engineers reviewing the MC9S08GT16AMFBE datasheet, MC9S08GT16AMFBE pinout, MC9S08GT16AMFBE application, or MC9S08GT16AMFBE equivalent, key selection criteria include Flash endurance at 1.8 V, copper-wire QFN-32 package compatibility, real-time interrupt in Stop3 mode, background debug via single-wire BKGD, and integrated LVD/COP protection for robust embedded operation.
Technical Context
The MC9S08GT16AMFBE implements the HCS08 CPU core with HC08 instruction set extension (BGND), supports up to 32 interrupt/reset sources, and features a programmable internal clock generator with FLL, enabling bus frequencies from 100 kHz to 40 MHz using internal RC, external crystal (32 kHz–4 MHz), or external clock input. Its clock system includes ±0.2% trimming resolution and ±0.5% deviation across voltage/temperature.
Peripherals include two independent Timer/PWM modules (TPM1: 3-channel, TPM2: 2-channel), an 8-pin keyboard interrupt module (KBI), dual serial interfaces (SCI1/SCI2), SPI, I²C, and an 8-channel 10-bit ATD converter with configurable sample time and conversion trigger sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S08AC16CFUE | Same HCS08 core, 16 KB Flash, but 48-pin QFN; lacks RTI in Stop3 mode; no 20 mA I/O | Higher pin count supports more peripherals; less suitable for ultra-low-power battery nodes | Select when additional I/O or external memory interface is required; not drop-in due to package and RTI capability |
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+, 128 KB Flash, 16 KB RAM, 48 MHz; no native BDM, uses SWD | Higher performance and memory; requires different toolchain and debug infrastructure | Select for future-proofing or when migrating from 8-bit to 32-bit; not pin-compatible or software-compatible |
Compared with MC9S08GT16AMFBE, MC9S08AC16CFUE offers more I/O but sacrifices ultra-low-power RTI wake-up and high-drive pins, while S9KEAZ128AMLH delivers scalable performance at the cost of toolchain migration and loss of single-wire BDM simplicity.

FAQ
What is the package type and lead finish for MC9S08GT16AMFBE?
The MC9S08GT16AMFBE uses a 32-pin QFN package (case outline 98ASA00473D) with copper wire bonding and lead-free (Pb-free) matte tin finish. This replaces the earlier gold-wire variant (98ARH99035A) and complies with RoHS requirements while improving thermal conductivity and bond reliability.
Does MC9S08GT16AMFBE support debugging while in low-power stop modes?
Yes, MC9S08GT16AMFBE supports active background debug (BDM) in Stop1 and Stop2 modes when the BDMEN bit is set. However, Stop3 disables the BDM clock entirely - debugging requires wake-up first. The single-wire BKGD pin remains functional for reset and forced entry into background mode.
What is the minimum operating voltage for Flash programming on MC9S08GT16AMFBE?
The MC9S08GT16AMFBE supports Flash read, program, and erase operations down to 1.8 V, enabling in-system programming in battery-powered applications where supply voltage may dip below 2.0 V during brown-out conditions.
How many independent PWM channels does MC9S08GT16AMFBE provide?
The MC9S08GT16AMFBE integrates two Timer/PWM modules: TPM1 with three channels and TPM2 with two channels, delivering five independent, configurable PWM outputs. Each channel supports edge-aligned, center-aligned, and input-capture modes with programmable modulo and duty-cycle registers.
Is MC9S08GT16AMFBE compatible with the same development tools as older HCS08 devices?
Yes, MC9S08GT16AMFBE is fully supported by the CodeWarrior Development Studio for HCS08, P&E Micro's Multilink debug probes, and the OSJTAG open-source debugger. Its single-wire BKGD interface maintains backward compatibility with existing HCS08 hardware debug infrastructure and firmware loaders.
