The MSP430F5510IZQE: 25 MHz is the rated core speed. For a 16-bit RISC architecture, that translates to roughly 25 MIPS sustained — enough to handle a USB full-speed isochronous stream while polling a couple of UARTs and servicing a PWM loop. If your design needs tighter timing than that, you are looking at a Cortex-M3 or M4 part; if it only shuttles bytes between USB and a sensor, this core has headroom.
No extended-range qualification needed for those environments.
The core runs at 25 MHz. That is the rated clock speed for the MSP430 CPUXV2 in this device.
No official pin-compatible replacement is listed in the lifecycle record. For new designs, TI recommends evaluating active MSP430F5xx USB variants; for board repair, the surplus channel is the practical source.
