8 MHz clock paces the ADC sampling loop and LCD refresh. At this speed the 16-bit conversion runs at several ksps while keeping the CPU in low-power modes between reads. 256-byte RAM limits data buffering to a few dozen samples.
No pin-compatible alternative is listed in the current record. Other MSP430x4xx parts in the same 48-VQFN package (such as the MSP430FG437x series) may share the footprint but require firmware adaptation due to different memory and peripheral maps.
The core runs at 8 MHz, which is the maximum clock frequency for this device.
The part is listed with Tape & Reel and Cut Tape packaging options. RoHS and REACH compliance documentation is typically provided by Texas Instruments for this series; confirm specific certificate availability at quote time.
