MSP430G2112IPW20R runs at 16 MHz with a 16-bit MSP430 CPU16 core, 1 KB Flash, and 128 bytes of RAM.
No last-time-buy window remains through the franchised channel.
The Universal Serial Interface (USI) supports I²C and SPI, enough for a temperature sensor, an EEPROM, or a small display.
Yes, Texas Instruments lists the MSP430G2112IPW20R as Obsolete. No further production is planned, and no last-time-buy window is currently active. The only available stock is through independent surplus and broker channels.
TI has not published a direct pin-compatible successor for this exact order code. However, the MSP430G2xx family includes several 20-TSSOP devices with larger Flash and RAM that share the same footprint — for example, the MSP430G2231 or MSP430G2452 offer 2 KB or 8 KB Flash respectively, allowing a firmware-only migration without a board change.
Yes, the MSP430G2xx series is supported by Energia, the Arduino-like wiring framework for TI MCUs. The 1 KB Flash and 128 B RAM limit the sketch size and library overhead, but simple GPIO, ADC, and serial examples fit.
