The MSP430F67691IPZ is a 16-bit MCU with MSP430 CPUXV2 core at 25 MHz.
The 25 MHz clock runs the six sigma-delta channels and LCD refresh.
Within the MSP430F6xx family, the MSP430F67691IPZ shares the same 100-LQFP footprint and peripheral set with other density variants. For a drop-in with less Flash or RAM, look at the MSP430F676x1 series — same pinout, same sigma-delta ADC block. No exact second-source from another manufacturer is listed.
The MSP430F67691IPZ runs at 25 MHz on the MSP430 CPUXV2 core.
Texas Instruments provides RoHS and REACH compliance documentation for this part. No UL or IEC certification is listed in the standard spec sheet.
