Product details
Overview
MC9S08GT16CFDE from NXP (formerly Freescale) is an 8-bit HCS08 core microcontroller with 16 KB Flash, 1 KB RAM, and integrated peripherals including SCI, SPI, I²C, TPM, KBI, and ATD. It operates at up to 40 MHz bus frequency, supports multiple low-power stop/wait modes, and targets cost-sensitive embedded control in automotive body electronics and industrial sensors.
For engineers reviewing the MC9S08GT16CFDE datasheet, MC9S08GT16CFDE pinout, MC9S08GT16CFDE application, or MC9S08GT16CFDE equivalent, key selection criteria include its 48-pin QFN package, 16 KB flash endurance (100k erase/write cycles), 10-bit ATD with 8-channel multiplexing, and background debug interface via BKGD/MS pin.
Technical Context
The MC9S08GT16CFDE implements the HCS08 CPU core with 16-bit index register, 8-level hardware stack, and 15 addressing modes. Its Internal Clock Generator (ICG) supports four clock modes - FEI, FBE, FEE, and SCM - enabling flexible clock source selection between internal RC, external crystal (32 kHz–4 MHz), or external clock input.
Peripheral integration includes two 16-bit Timer/PWM modules (TPM1/TPM2) with input capture, output compare, and edge-aligned PWM; a 10-bit Analog-to-Digital Converter (ATD) with 8 inputs and software/hardware trigger support; and dual serial interfaces: one SCI (UART) and one SPI, plus I²C master/slave capability.

FAQ
What is the maximum operating frequency of the MC9S08GT16CFDE?
The MC9S08GT16CFDE supports a maximum bus frequency of 40 MHz, achieved via its Internal Clock Generator (ICG) in FEE mode using an external 4 MHz crystal and FLL multiplication. This determines instruction execution speed and peripheral timing resolution, with typical current consumption of 12 mA at 40 MHz/5 V.
Does the MC9S08GT16CFDE include hardware debug support?
Yes, the MC9S08GT16CFDE integrates Background Debug Mode (BDM) accessible through the PTG0 pin. This single-wire interface enables full in-circuit debugging, flash programming, and real-time register inspection without requiring additional debug headers or JTAG circuitry - simplifying development and field updates.
What analog-to-digital capabilities does the MC9S08GT16CFDE provide?
The MC9S08GT16CFDE features a 10-bit Analog-to-Digital Converter (ATD) with 8 input channels multiplexed across Port B pins. It supports software or hardware triggering, configurable sample time, and conversion results stored in 16-bit registers - sufficient for precision sensor interfacing in automotive and industrial applications.
How many serial communication interfaces are integrated into the MC9S08GT16CFDE?
The MC9S08GT16CFDE integrates three serial interfaces: one SCI (UART), one SPI, and one I²C module. SCI supports full-duplex asynchronous communication; SPI provides synchronous master/slave operation; and I²C enables multi-master, multi-slave communication on shared buses - covering most embedded interconnect needs.
What low-power modes are supported by the MC9S08GT16CFDE?
The MC9S08GT16CFDE supports Run, Wait, and three Stop modes (Stop1–Stop3). In Stop3 mode with LVD disabled and RTC active, typical current draw is 1.5 µA - enabling multi-year battery operation in sensor nodes. All modes retain RAM content and support wake-up via IRQ, KBI, RTI, or SCI activity.
