The MSP430F6725IPN: The core runs at 25 MHz. The 128 KB Flash needs one wait state for zero-wait execution.
128 KB Flash and 4K x 8 RAM — sizing the firmware
The 4K x 8 RAM is tight for large data buffers; if your design streams ADC samples or holds a display frame buffer, budget the RAM usage early. The Flash is field-reprogrammable via the bootloader or JTAG/SWD.
Dual ADC — 5-channel 10-bit plus 2-channel 24-bit sigma-delta
The integrated ADC array is what sets this part apart from simpler MSP430s: five 10-bit SAR channels for fast, moderate-resolution measurements (e.g., current sensing, button thresholds), and two 24-bit sigma-delta channels for high-precision tasks like weight scales, pressure transducers, or energy-monitoring front ends. Both converters share the same voltage reference and can be sequenced by the DMA controller, which keeps the CPU free for other work.
