16-bit MSP430 for sensor-level control
It integrates 8KB of Flash program memory and 256 x 8 bytes of RAM, running at a core speed of 8MHz. With 22 general-purpose I/O lines, an 8-channel 10-bit ADC, and SPI plus UART/USART serial interfaces, it is sized for embedded control applications that read analog sensors and communicate over a serial bus — think temperature monitors, flow meters, or simple motor-control panels in industrial and commercial equipment.
Memory and performance — what fits where
The 8KB Flash and 256B RAM place this part in the low-end of the MSP430x1xx family. It handles a single control loop with a modest state machine and a handful of sensor readings, but it is not sized for data logging, USB stacks, or RTOS-based multitasking. The 8MHz core speed is adequate for polling a sensor at 1 kHz or servicing a UART at 115.2 kbaud; if your application needs faster ADC sampling or more memory, the MSP430x1xx family has larger Flash and RAM options in the same 28-SOIC footprint.
