This is a low-pin-count, low-power controller suited for sensor interface, basic control loops, and battery-powered monitoring where code footprint stays under 1 KB.
1 KB Flash and 128 bytes RAM — sizing the firmware budget
With 1 KB of Flash (organized as 1K x 8 plus 256 bytes) and 128 bytes of RAM, the MSP430F2001TPWR is a tight-fit part. The program memory holds a single-purpose control routine — think a temperature monitor with a PWM fan output or a simple timer-based sequencer. The 128-byte RAM limits stack depth and data buffers; interrupt service routines need to be lean. For designs that need more headroom, the MSP430F2xx family offers pin-compatible density upgrades with larger Flash and RAM, but this exact code is the entry-level option.
Package and mounting — 14-TSSOP with surface-mount assembly
Housed in a 14-TSSOP package (0.173" body width, 4.40 mm pitch), the MSP430F2001TPWR is a surface-mount device intended for automated pick-and-place. The supplier device package is 14-TSSOP. The tape-and-reel variant (TR) and cut-tape (CT) options are available for both production reels and prototype quantities.
The base product number is MSP430F2001, and the series is MSP430F2xx.
