1 KB Flash, 128 B RAM — memory floor for the BOM
The MSP430F2002IPWR: It carries 1 KB of program Flash and 128 bytes of RAM, which sets the firmware and data-buffer ceiling for the design. At 16 MHz the core delivers enough throughput for sensor polling, simple control loops, and serial-interface management without burning through the power budget.
On-chip peripherals — what the integrated ADC and serial interfaces mean for the board
That peripheral set means a single-chip solution for applications like temperature monitoring, simple motor control, or battery-management front ends — no external ADC or serial transceiver needed. The 10 available I/O lines (in the 14-TSSOP package) are enough for a handful of sensors, a small keypad, or status LEDs, but the 128-byte RAM limits buffering to a few frames of sensor data before the firmware must process and store to Flash.
14-TSSOP footprint — board-area and assembly considerations
No exposed thermal pad, so the junction-to-ambient thermal path relies on the leadframe and PCB copper.
