16 MHz, 1 KB Flash — the resource budget for this MSP430
The MSP430F2002TPW: It runs at 16 MHz and carries 1 KB of Flash program memory (1K x 8 plus 256 B) with 128 bytes of RAM (128 x 8). This is a resource-constrained part — the firmware engineer must fit the application, interrupt vectors, and any bootloader into 1 KB of code space, and the 128-byte RAM budget forces careful management of stack depth, local variables, and communication buffers.
Brown-out detect and POR are integrated on-chip.
The 105°C upper limit provides headroom above the standard 85°C commercial grade, which is important when the MCU is placed near a power transistor or inside a sealed enclosure. The 14-TSSOP package is a fine-pitch surface-mount package (0.173" body width, 4.40 mm) that suits automated assembly but requires careful PCB land pattern design — the 0.65 mm pitch calls for a standard TSSOP-14 footprint.
For new designs, the 1 KB Flash and 128 B RAM are the binding constraints — if the firmware grows beyond that, the next step up in the MSP430F2xx family (same pin-compatible 14-TSSOP footprint, larger memory options) is the natural migration path.
