4 KB Flash and 256-byte RAM — sizing the firmware budget
It will not accommodate a full TCP/IP stack or large data buffers. If the application needs more code space or RAM, consider a pin-compatible upgrade within the MSP430x1xx family that offers higher Flash density and more SRAM while keeping the same 20-SOIC footprint.
The integrated slope A/D converter provides a low-component-count method for reading resistive sensors (thermistors, RTDs, strain gauges) without an external ADC. The POR (power-on reset) and WDT (watchdog timer) peripherals are included on-chip, reducing external supervisor IC requirements.
