FAQ

What is the maximum operating frequency of the MC908GZ60MFUE?

The MC908GZ60MFUE achieves a maximum core frequency of 20 MHz using its integrated PLL, which multiplies an external crystal input (e.g., 4 MHz) by up to ×32. The resulting CGMXCLK feeds the internal bus clock divider, yielding a 20 MHz BUSCLK when configured with /2 division. This frequency is fully supported across the specified voltage (2.7–5.5 V) and temperature (–40°C to +125°C) ranges per the Rev. 6.0 datasheet.

Does the MC908GZ60MFUE support in-system programming (ISP)?

Yes, the MC908GZ60MFUE supports in-application programming (IAP) through its dual Flash memory architecture (Flash-1 and Flash-2). Firmware can execute from one Flash bank while erasing or programming the other, enabling field updates without external programmers. The CONFIG register provides write-protection bits to safeguard critical code sections, and the background debug mode (BDM) allows full ISP via a single-wire interface.

How many analog input channels does the ADC in the MC908GZ60MFUE support?

The MC908GZ60MFUE integrates a 12-bit successive approximation ADC with 24 configurable analog input channels mapped across Ports A, B, and G (e.g., AD0–AD23). These channels share a common sample-and-hold circuit and support programmable conversion time (1–16 µs), multiple justification modes (left/right/signed), and hardware trigger sources including TIM overflow and ESCI receive events - all documented in Chapter 3 of the Rev. 6.0 datasheet.

Is the MC908GZ60MFUE pin-compatible with other devices in the GZ series?

Yes, the MC908GZ60MFUE shares the same 64-pin QFP package and pinout with the MC908GZ48MFUE and MC908GZ32MFUE variants. Differences are limited to Flash size (60/48/32 KB) and RAM allocation (2 KB across all), with identical peripheral placement, register maps, and electrical characteristics - enabling hardware reuse across product tiers per Section 1.4 and Table 22-1 of the Rev. 6.0 datasheet.

What debug interface does the MC908GZ60MFUE provide?

The MC908GZ60MFUE features a single-wire Background Debug Mode (BDM) interface compliant with the Freescale BDM specification. This allows full in-circuit debugging - including breakpoint setting, register inspection, and memory read/write - without halting real-time peripherals like TIM or MSCAN. The interface uses the BKGD pin (shared with Port D, Pin 6) and requires no additional pins, making it ideal for space-constrained PCB layouts.
