The 25 MHz core handles a USB interrupt-driven stack plus a control loop without external DMA offload. The on-chip DMA controller handles memory-to-peripheral transfers.
The on-chip USB PHY supports device, host, and OTG modes. The dedicated PLL generates the clock from the internal oscillator.
The MSP430F5507IRGZT runs at 25 MHz on the MSP430 CPUXV2 core. That clock rate is sufficient for USB stack handling plus real-time control loops without external DMA.
The MSP430F5508IRGZT is a pin-compatible drop-in with 48 KB Flash instead of 32 KB — same package, same peripheral set, same USB PHY. A firmware recompile is all that is needed to move up in memory.
