TI lists the MSP430F5659IPZ as Active. No last-time-buy or EOL notice is recorded, so it remains a safe choice for production BOMs.
The CPUXV2 core runs at 20 MHz.
Within the MSP430F5xx family, devices with the same 100-LQFP footprint and similar peripheral sets (USB + ADC + DAC) share pin compatibility; verify the exact memory and feature match against your firmware image.
