Product details

Industrial temperature grade and supply flexibility

Rated for -40°C to 105°C, this MCU operates from a 1.8 V to 3.6 V supply. The internal oscillator eliminates an external crystal for basic timing.

4 KB Flash — sizing the firmware budget

With 4 KB of Flash and 512 B of RAM, the MSP430F2122TPWR is aimed at code-constrained applications: a single control loop with a few state machines, a Modbus RTU slave, or a simple sensor-logging task. No room for a full RTOS or large lookup tables — plan for bare-metal or small-scheduler firmware.

Lifecycle and sourcing reality

Frequently asked questions

Is MSP430F2122TPWR obsolete?

The MSP430F2122TPWR is marked with an EOL hot lifecycle status, indicating production is winding down. It is still listed as Active, but buyers should plan for last-time-buy or a replacement.

What is the operating voltage of MSP430F2122TPWR?

The supply voltage range is 1.8 V to 3.6 V.
