Procurement Notes

Verify the specific model suffix to confirm hardware configuration. The UC5550-67HFN designation indicates the absence of Wi-Fi and Ethernet PHY components on this specific variant. Ensure compatibility with the required peripheral count, as non-standard peripherals may share I/O pins and reduce availability. Consult official documentation for bootloader version requirements before deployment.

Selection Notes

Select the UC5550-67HFN when Wi-Fi and integrated Ethernet PHY are not required, distinguishing it from variants like the UC5550-67HFW. This model provides access to USB Host, parallel LCD, and DCMI interfaces. Developers must account for shared I/O pins among non-standard peripherals, which may limit simultaneous usage. Confirm that the 216 MHz Cortex-M7 performance meets application timing constraints.

Part Context

The UC5550 series represents an upgrade over the UC2550, offering increased processor speed, internal flash, external RAM, and additional peripherals. The UC5550-67HFN is part of the Universal Compute Module (UCM) family, designed for use with TinyCLR OS. Customized versions with varying memory sizes are available upon request from the manufacturer.

Replacement Considerations

The UC5550-67HFW serves as a direct functional alternative if Wi-Fi capability is required instead of the base configuration. Other models in the UC5550 series offer different memory configurations or customization options. Verify pinout compatibility and software support when transitioning between variants within the same family.
