The LM3S5737-IQC50-A0: TI does not accept new design registrations for this part.
Brown-out detect and POR are integrated, so the reset supervisor can be a simple RC or a dedicated monitor if the system already uses one.
The 64 KB SRAM and 128 KB Flash are available for firmware and data storage.
New board designs should target a current-production Cortex-M3 or M4 alternative.
Yes.
