The Texas Instruments MSP430F112IDW is a 16-bit MCU built around the MSP430 CPU16 core, clocked at 8 MHz from an internal oscillator. The 14 I/O lines, POR, PWM, and WDT peripherals cover basic control and timing tasks without external glue logic. Packaged in a 20-SOIC (7.50 mm wide) surface-mount body, it fits standard pick-and-place lines and reflow profiles. The 20-SOIC footprint is common across the MSP430x1xx series.
Texas Instruments has not published an official direct replacement order code for the MSP430F112IDW. For a pin-compatible alternative within the same family, look at other MSP430x1xx devices in the 20-SOIC package — the Flash and RAM sizes differ, so verify code fit and peripheral set before substituting.
The supply range is 1.8 V to 3.6 V, covering single Li-ion or dual alkaline configurations without an external regulator.
