16 MHz MSP430 core with 8 KB Flash for low-power control
On-chip peripherals include a brown-out detect and reset, power-on reset, PWM timer, and watchdog timer. An internal oscillator eliminates the need for an external crystal in many designs, and the slope A/D converter handles basic analog sensing without an external ADC.
Active lifecycle — no obsolescence concern
The MSP430F2131IDGVR carries an active product status. There is no last-time-buy notice or end-of-life announcement. The part is still in regular production through Texas Instruments and its authorized channel.
