16 MHz MSP430 core in a 14-TSSOP footprint
The MSP430G2132IPW14 is a 16-bit microcontroller from the MSP430G2xx family, built around the MSP430 CPU16 core clocked at 16 MHz. It packs 1KB of Flash program memory and 128 x 8 bytes of RAM, with 10 general-purpose I/O lines brought out to the 14-TSSOP package. This is a low-pin-count part aimed at cost-sensitive embedded control — think sensor nodes, simple human-interface devices, or auxiliary monitoring in a larger system. The 14-TSSOP body (4.40 mm wide) is a common footprint for space-constrained boards and reworks cleanly under hot air if the pad layout is generous.
Peripherals and connectivity for small-footprint control
The integrated 8-channel 10-bit ADC reads analog signals directly, so a separate converter IC is not needed for low-resolution sensing. Serial connectivity comes via I²C, SPI, and the Universal Serial Interface (USI), which handles both synchronous protocols. The operating temperature range spans -40°C to 85°C, covering industrial enclosures and outdoor equipment that sees seasonal swings.
Active production and compliance status
The part is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free assembly. The base product number is MSP430G2132; the IPW14 suffix denotes the 14-TSSOP package in tube packaging.
