Questions about this item

What external hardware is required to program and debug the AT91SAM7SE256B-AU after soldering it to a 128-pin LQFP board?

A compatible JTAG or SWD debugger and a suitable power supply are needed to program the device once it is mounted on a custom PCB with the 128-pin LQFP footprint.

Can the AT91SAM7SE256B-AU share a 128-pin LQFP footprint with older AT91SAM7S parts that have less flash memory?

The 128-pin LQFP package matches other AT91SAM7S devices, so the same PCB footprint can be used, but firmware must account for the 256 KB flash size difference.

How can I verify the AT91SAM7SE256B-AU is running correctly after the first power-up?

Connect a debugger to the JTAG or SWD port, halt the core, and confirm the device ID register reads the expected AT91SAM7SE256B signature.
