116 KB Flash and 8 KB RAM — what the memory budget buys
The 116 KB Flash (organized as 116K x 8 plus 256 B for info storage) is sized for moderate firmware stacks — a real-time OS kernel, communication protocol libraries, and application code for a multi-sensor data logger or a Modbus RTU slave. The 8 KB RAM handles the stack and a few hundred bytes of runtime variables; anything beyond that pushes you to external SRAM or a larger member of the MSP430F2xx family. The 256 B of info Flash is useful for calibration constants or node ID that survive a full erase.
16 MHz core speed — where it fits and where it doesn't
At 16 MHz the core executes most instructions in one or two cycles. The internal oscillator saves an external crystal.
Peripherals and connectivity
On-chip peripherals include a DMA controller, PWM timer, watchdog timer, and a 12-bit ADC with 8 multiplexed channels. For serial communication the part supports I²C, SPI, UART/USART, IrDA, and LINbus.
