Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin compatibility and package dimensions. Ensure that the selected variant matches the required memory configuration and interface availability for your design constraints.

Microcontrollers Selection Notes

Select this component when a balance of processing power and integrated connectivity is required. The inclusion of hardware encryption and multiple serial interfaces reduces external component count. Consider the 144-pin package size and thermal requirements during the initial layout phase.

Microcontrollers Part Context

This part belongs to the MCF5225x series, which shares a common architecture but varies in memory size and package options. The CVN66 suffix denotes the specific temperature range, package type, and clock frequency configuration distinct from other family members like the MCF52259.

Microcontrollers Replacement Considerations

Compatible substitutes within the same family include the MCF52259CVN80, which offers higher clock speeds and larger memory. Verify pin-to-pin compatibility and software register mapping before implementing any cross-model replacements.
