Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC908GP32CFBE | 32 KB FLASH, same pinout and peripheral set; higher memory headroom for complex firmware | Preferred where bootloader, OTA updates, or multi-sensor fusion require >16 KB code space | Select when future firmware growth or dual-application partitioning is anticipated |
| S9KEAZ128AMLH | ARM Cortex-M0+ core, 128 KB FLASH, 16 KB RAM; different architecture and toolchain | Used in next-generation designs requiring higher throughput, USB, or RTOS support | Choose for migration paths requiring scalability, not drop-in replacement |
Compared with MC908GP16CFBE, the MC908GP32CFBE offers identical peripheral compatibility and footprint but doubles FLASH capacity for feature-rich firmware, while the S9KEAZ128AMLH provides architectural modernization at the cost of software rework and new qualification effort.

FAQ
What is the maximum operating frequency of the MC908GP16CFBE?
The MC908GP16CFBE supports a maximum bus frequency of 8 MHz, derived from its internal PLL-based Clock Generator Module. This frequency governs instruction execution speed, peripheral timing, and ADC conversion rate. The PLL accepts input clocks from 32 kHz to 8 MHz and multiplies them by factors of 1–32, allowing precise clock synthesis for diverse system requirements while maintaining stability across voltage and temperature ranges.
Does the MC908GP16CFBE include hardware debug support?
Yes, the MC908GP16CFBE features Background Debug Mode (BDM) accessible via a single-wire interface. This allows non-intrusive firmware programming, real-time register and memory inspection, and breakpoint execution without requiring dedicated debug pins or halting normal operation. BDM is fully supported by Freescale's CodeWarrior development tools and third-party debug probes compatible with the HCS08 BDM protocol.
How many analog input channels does the ADC in the MC908GP16CFBE support?
The MC908GP16CFBE integrates a 10-bit successive-approximation ADC with eight analog input channels (AD0–AD7), mapped to PTB0–PTB7. These channels share pins with Port B digital I/O, enabling flexible configuration. Conversion time is programmable down to 12 µs per sample, and the module supports both single-ended and differential input modes with internal reference options (VREFH/VREFL).
What low-power modes are available on the MC908GP16CFBE?
The MC908GP16CFBE supports two hardware low-power modes: Wait and Stop. In Wait mode, the CPU halts while peripherals remain active and can generate interrupts to resume execution. In Stop mode, both CPU and most peripherals are disabled except for wake-up sources like IRQ, KBI, SCI, or RTC. Typical Stop-mode current is under 1 µA, making it suitable for battery-powered applications requiring multi-year operation.
Is the MC908GP16CFBE pin-compatible with other devices in the GP family?
Yes, the MC908GP16CFBE shares the same 44-pin QFP (case 824A) package and pin assignment with the MC68HC908GP32 and MC908GP8CFBE. This enables hardware reuse across variants differing only in FLASH size (8 KB, 16 KB, or 32 KB) and RAM allocation, simplifying PCB design and reducing qualification effort when scaling firmware complexity.
