Product details
Overview
MC9S08GT16AMFDE 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, two 3-channel and one 2-channel TPM timers, and keyboard interrupt module - used in industrial control panels, appliance motor controllers, and smart sensor nodes requiring low-power embedded processing.
For engineers reviewing the MC9S08GT16AMFDE datasheet, MC9S08GT16AMFDE pinout, MC9S08GT16AMFDE application, or MC9S08GT16AMFDE equivalent, key selection criteria include QFN-32 package compatibility, 1.8–3.6 V operation, on-chip FLL clock generation, background debug interface, and Flash security features for firmware protection in cost-sensitive OEM designs.
Technical Context
The MC9S08GT16AMFDE implements the HCS08 CPU core with HC08 instruction set extension (BGND), supporting up to 32 interrupt/reset sources and three ultra-low-power stop modes. Its internal clock generator includes FLL with ±0.5% deviation over voltage/temperature and ±0.2% trimming resolution.
Peripherals are tightly integrated: ATD converter supports 10-bit sampling at up to 1.25 MSPS; dual SCI modules enable asynchronous serial communication; SPI and I²C support master/slave operation; TPM modules deliver PWM, input capture, and output compare with flexible channel grouping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S9KEAZ128AMLH | Kinetis E-series ARM Cortex-M0+ core, 128 KB Flash, 16 KB RAM, higher performance but larger footprint and higher voltage min (2.7 V) | Requires PCB redesign for 64-pin LQFP; not drop-in compatible due to different peripheral register map and debug interface | Select when migrating to ARM architecture with need for USB, CAN, or higher throughput; not suitable for direct replacement |
| MC9RS08KA2 | Smaller 8-bit RS08 core, 2 KB Flash, 128 B RAM, 20 MHz max, 8-pin DFN package | Limited peripherals (no I²C, single SCI, no TPM); suited only for ultra-simple supervisory tasks | Choose only for minimal-cost, space-constrained functions where MC9S08GT16AMFDE capabilities are excessive |
Compared with S9KEAZ128AMLH and MC9RS08KA2, the MC9S08GT16AMFDE delivers optimal balance of Flash/RAM capacity, peripheral richness, and QFN-32 compactness for mid-tier 8-bit control - avoiding ARM migration complexity while exceeding entry-level MCU limitations.

FAQ
What is the operating voltage range for the MC9S08GT16AMFDE?
The MC9S08GT16AMFDE operates from 1.8 V to 3.6 V across its entire temperature range (–40°C to +105°C). Its Flash memory supports read/program/erase operations down to 1.8 V, enabling robust low-voltage operation in battery-powered or wide-input industrial power supplies. This range is confirmed in Section 4.4.1 and Appendix A of the MC9S08GT16A Rev. 1 datasheet.
Does the MC9S08GT16AMFDE support in-circuit debugging?
Yes, the MC9S08GT16AMFDE includes a single-wire background debug interface (BDM) with on-chip in-circuit emulation (ICE) capability. It supports real-time bus capture, two hardware breakpoints, and a single software breakpoint during active debugging. The BKGD/MS pin serves as the dedicated debug port, and all functionality is documented in Chapter 15 and Section 2.3.4 of the MC9S08GT16A Rev. 1 datasheet.
What package type and dimensions does the MC9S08GT16AMFDE use?
The MC9S08GT16AMFDE uses a 32-pin QFN package (case outline 98ASA00473D), measuring 5 mm × 5 mm with 0.5 mm pitch and an exposed thermal pad. This copper-wire QFN variant replaced the earlier gold-wire version (98ARH99035A), as specified in Freescale's QFN Addendum Rev. 0 (July 2014). Mechanical drawings are provided in Appendix B of the MC9S08GT16A datasheet.
Can the MC9S08GT16AMFDE generate PWM signals for motor control?
Yes, the MC9S08GT16AMFDE integrates three Timer/PWM (TPM) modules: two 3-channel and one 2-channel units. These support center-aligned and edge-aligned PWM, input capture, output compare, and quadrature decoding - directly enabling brushless DC motor commutation, fan speed control, or LED dimming. Configuration details appear in Chapter 10 of the MC9S08GT16A Rev. 1 datasheet.
Is Flash memory security available on the MC9S08GT16AMFDE?
Yes, the MC9S08GT16AMFDE provides Flash block protection and full chip security via the FOPT and FPROT registers. Once secured, the Flash cannot be read or reprogrammed without a mass erase, preventing unauthorized firmware extraction or modification. This feature is detailed in Sections 4.4.6, 4.5, and 4.6.4 of the MC9S08GT16A Rev. 1 datasheet.
