The MSP430F5634IPZ is a 16-bit MCU from the MSP430F5xx family, running at 20 MHz. It carries 192 KB of Flash program memory and 18 K x 8 of RAM.
At 20 MHz the core executes most instructions in one or two cycles. The 192 KB Flash is sized for a moderate firmware image.
The supply voltage range is 1.8 V to 3.6 V, covering both 3.3 V and 1.8 V logic rails.
No official direct replacement is listed for this order code. The MSP430F5xx family includes pin-compatible siblings with different Flash and RAM densities in the same 100-LQFP footprint; verify the peripheral set against your firmware before substituting.
