Package and mounting
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
With 128 KB of program Flash and 4K x 8 of RAM, this MCU fits applications that need a moderate firmware footprint — think metrology algorithms, LCD-driven user interfaces, or protocol stacks for I²C, SPI, UART, and LIN. 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.
Industrial temperature grade and 80-LQFP package
The 80-LQFP package (12x12 mm body) is a standard fine-pitch QFP.
