The 28-pin TSSOP package and 1.8 V to 3.6 V supply range suit it for battery-operated or low-power sensor nodes in industrial control, portable instrumentation, and building automation. ## 8 MHz — enough for a control loop, not for heavy number crunching The 8 MHz clock is the headline rating here. For a 16-bit RISC core, that translates to roughly 8 MIPS. It handles a PID loop, a Modbus RTU poll cycle, or reading the ADC at a few kHz without breaking a sweat. But if your firmware runs floating-point math or a protocol stack with large buffers, the 256-byte RAM will pinch before the core speed does. No AEC-Q100 automotive grade here, so skip it for under-hood or chassis-domain applications unless you have your own qualification data. The MSP430A081IPWR has an EOL hot lifecycle flag. Official status is Active, but the EOL signal suggests limited factory availability.","metaTitle":"TI MSP430A081IPWR 16-bit MCU, 8 MHz, 8 KB Flash, 28-TSSOP","metaDescription":"MSP430A081IPWR 16-bit MCU with 8 MHz core, 8 KB Flash, 256 B RAM, 8-ch 10-bit ADC, -40°C to 85°C.
