Product details

16-bit MSP430 core with 1 KB Flash — right-sized for sensor and control loops

The 20-pin DIP package with 16 general-purpose I/Os and a USI module supporting I²C and SPI makes it a fit for low-pin-count embedded control in industrial sensor interfaces, battery-powered instrumentation, and simple human-machine interface panels.

With 16 I/Os in a 20-pin DIP, the part suits through-hole prototyping and low-volume production where surface-mount assembly is not justified.

The 16 MHz core speed is maintained across the full temperature range, so timing-critical loops in PWM generation or serial communication do not require derating at the extremes.

Frequently asked questions

Does MSP430G2102IN20 have an internal oscillator?

Yes, the MSP430G2102IN20 includes an internal oscillator, so no external crystal or ceramic resonator is required for basic operation. This simplifies the BOM and saves board space in low-cost embedded designs.

What is MSP430G2102IN20's listed speed?

The MSP430G2102IN20 is rated for a 16 MHz core speed. This is the maximum clock frequency supported by the internal oscillator and the CPU core, sufficient for sensor polling, serial communication, and simple control loops.
