Trivia

The MSP430 microcontroller was the brainchild of TI engineer Daniel Meyer. Dubbed the “World's Lowest Power Microcontroller”, the MSP430 boasts an ultra-low power design and can draw less than 1 µA/MHz in active mode and less than 5 µA in standby. In addition to its efficient power usage, the MSP430 also offers a wide range of features, including up to 16 MIPS, 20-bit addressing, 8-bit or 16-bit instructions, up to 256KB Flash, up to 16KB RAM, and various peripherals. In a humorous twist, the MSP430 is also known as the “Mighty Small Processor”, a nickname that reflects its tiny size, but also its ability to outperform larger, more expensive microcontrollers.
