16 MHz MSP430 CPU16 with 8.5 KB FRAM — the non-volatile memory that writes like RAM
Alongside that sits 2K x 8 of SRAM for stack and scratchpad.
15 I/O, I²C/SPI/UART, 8-channel 10-bit ADC — peripheral set for sensor and control loops
The integrated 8-channel 10-bit ADC samples analog signals directly, saving an external converter. Internal oscillator means you can run without a crystal for many applications, though the internal RC is accurate enough for UART timing at common baud rates.
24-VQFN (4x4) with exposed pad — layout and rework notes
That pad needs a via array to the ground plane to pull heat out of the die — without it, the junction temperature climbs faster under continuous load. For rework, the QFN profile is standard: preheat the board to 150°C, hot-air nozzle over the package, and tweezers lift once the solder flows. Surface-mount only, no through-hole variant.
