The 256-byte information memory block (included in the 2 KB total) stores calibration constants or bootloader parameters without eating into the main program space. For a design that fits a 1.5 KB firmware image and a handful of global variables, this part avoids the cost jump to the 4 KB or 8 KB MSP430 siblings. If your firmware needs a USB stack, a real-time OS, or any significant data buffer, you will overflow the RAM before the Flash — step up to the MSP430F21x2 or F22xx series. ## Temperature grade and supply — where it runs The 1.8 V minimum is the key number for battery-life budgeting — the core draws less current at lower Vcc, and the Flash read path remains operational down to that floor. ## 20-SOIC wide-body — footprint and layout The 20-SOIC package with 0.295-inch (7.50 mm) body width is the wide-body variant. Verify your PCB footprint library has the 7.50 mm body width before routing. The ROHS3 compliance covers EU regulatory requirements through the current production cycle.","metaTitle":"Texas Instruments MSP430F2111TDW 16-bit MCU, 16MHz","metaDescription":"MSP430F2111TDW 16-bit MCU from TI's MSP430F2xx series. 16MHz core, 2KB Flash, 128B RAM, 16 I/O, -40°C to 105°C, 1.8V-3.6V.

Within TI's own MSP430F2xx family, the MSP430F2112 is a functional upgrade with 4 KB Flash and 256 bytes RAM in the same 20-SOIC package — it is a drop-in replacement if your firmware needs more memory headroom, but it is not a lower-cost alternate. The F280041PZQR from the C2000 family is a different architecture (32-bit C28x at 100 MHz) and is not a functional substitute."},{"question":"Can MSP430F2111TDW be programmed with an MSP430 programmer?","answer":"Yes. The MSP430F2111TDW uses the standard MSP430 Spy-Bi-Wire (2-wire JTAG) or 4-wire JTAG programming interface.
