20 MHz clock on the 16-bit RISC core. Enough for a PID loop at a few kHz or USB polling at full-speed.
192 KB Flash and 18 KB RAM. 16-channel 12-bit ADC. Brown-out detect and POR on-chip.
The MSP430F5635 (256 KB Flash) is a pin-compatible upgrade in the same 100-LQFP package and MSP430F5xx family. Verify firmware memory map and USB descriptor size before swapping; the core, peripherals, and pinout match.
The MSP430F5634IPZR runs at 20 MHz on the MSP430 CPUXV2 core.
It belongs to the MSP430F5xx series of ultra-low-power 16-bit MCUs from Texas Instruments.
