The 25 MHz core delivers around 25 MIPS in single-cycle execution. That handles a USB interrupt service routine, SPI peripherals, and a control loop.
The MSP430F5502IRGZR carries an EOL/hot lifecycle flag. TI lists the base product as active, but the specific IRGZR variant is in phase-out.
The CPUXV2 core runs at 25 MHz, delivering about 25 MIPS in single-cycle execution.
Within the MSP430F5xx family, the MSP430F5510 offers 32 KB Flash and 4 KB RAM in the same 48-VQFN package, but verify the USB register map and peripheral set before substituting.
