• Industrial Ethernet gateways
• IP-based security cameras

Microprocessors Procurement Notes

Verify the specific suffix '100' against official Microchip documentation to confirm it denotes the standard commercial/industrial grade variant within the AT91SAM9260 family. Ensure compatibility with existing PCB footprints for the 217-ball LFBGA package. Confirm that the selected revision matches the required software bootloader support for Linux or Windows CE environments.

Microprocessors Selection Notes

Select this component when a pin-compatible upgrade from ARM7 controllers is required while maintaining software portability. It is suitable for designs needing embedded OS support such as Linux. Consider the 180 MHz performance limit and verify if external memory expansion via the EBI meets storage requirements beyond the internal 32 kB ROM.

Microprocessors Part Context

This part belongs to the AT91SAM9260 series, representing Microchip's initial line of 32-bit microcontrollers compatible with ARM9 cores. The series maintains programming model consistency with previous ARM7 devices, facilitating easier migration for developers. It serves as a foundational platform for complex embedded applications requiring multimedia and networking interfaces.

Microprocessors Replacement Considerations

The AT91SAM9G20 is a documented pin-compatible successor in the same family, offering higher clock speeds and increased cache capacity. Verify if the target application can utilize the updated specifications of the G20 series before selecting alternative components.
