192 KB Flash is generous for a 16-bit MCU — it holds a full application stack including a USB stack, a small RTOS, and a bootloader with room for field-update images. The 18 KB RAM, though, is the tighter constraint. If your design streams USB audio or buffers large sensor arrays, you'll need to budget that 18 KB carefully; the DMA controller helps move data without CPU intervention.
There is no direct pin-compatible drop-in replacement from TI that matches the 192 KB Flash, 18 KB RAM, and USB 2.0 in this 113-BGA package. The MSP430F5659 offers more RAM (32 KB) but uses a different pinout and package. For a new design, consider migrating to a currently active MSP430F5xx or MSP430FRxx variant with similar peripheral set.
The core runs at 20 MHz.
It belongs to the MSP430F5xx series.
