Product details

16-bit MCU with 2 KB Flash — what it fits

The 16 general-purpose I/O pins and integrated peripherals — brown-out detect/reset, POR, PWM, and watchdog timer — cover common embedded tasks without external glue logic.

2 KB Flash — sizing the firmware budget

2 KB of Flash and 128 bytes of RAM fit a single-purpose firmware image — a temperature logger, a PWM fan controller, or a simple I²C bridge.

20-TSSOP — rework and layout notes

The 20-TSSOP package (0.173" body width, 4.40 mm) is a fine-pitch but hand-reworkable part. The 20-pin footprint is standard for TSSOP-20; no special via pattern needed.

This is a mainstream TI MSP430 part, widely stocked through distribution. For dual-sourcing or a higher-performance alternative, the F280041PZQR (C2000 C28x core, 32-bit, 100 MHz) is a different architecture and not pin-compatible — it is not a direct second source. Within the MSP430F2xx family, the MSP430F2131IPWR (4 KB Flash) shares the same 20-TSSOP footprint and peripheral set, offering a straightforward memory upgrade path without a board spin.

Frequently asked questions

What is the maximum operating temperature of MSP430F2111IPWR?

The maximum operating temperature is 85°C (ambient), with a minimum of -40°C, covering the industrial temperature range.

What is the difference between MSP430F2111IPWR and MSP430F2131IPWR?

Both are 16-bit MSP430F2xx MCUs in the same 20-TSSOP package with identical pinout and peripheral set. The MSP430F2131IPWR doubles the program memory to 4 KB Flash, while the MSP430F2111IPWR has 2 KB. If firmware size is the constraint, the F2131 is a drop-in upgrade without a board change.

What programmer is required for MSP430F2111IPWR?

The MSP430F2111IPWR uses the standard Spy-Bi-Wire (SBW) 2-wire JTAG interface for programming and debugging. Any TI MSP430 programmer — the MSP-FET, MSP-FET430UIF, or a third-party tool like the LaunchPad's onboard debugger — works. The SBW interface uses the RST and TEST pins, so the 20-TSSOP package exposes both on pins 16 and 17.
