25 MHz core — what it buys you
At 25 MHz the core can sustain a 16-bit multiply-accumulate in a single cycle. The 6 KB RAM is tight for buffered USB transfers — plan the DMA channels to move data directly between USB FIFO and memory.
Obsolete — sourcing reality
TI has marked the MSP430F5513IRGCT as obsolete. No official successor part number is listed in the product-change notice. For BOM lines that cannot migrate, the remaining supply moves through independent and surplus channels. We source and quote this part to order against an RFQ — availability and current pricing are confirmed at quote time, not on a static listing.
