Sixteen general-purpose I/O lines are available, along with on-chip peripherals including brown-out detect and reset (BOR), power-on reset (POR), a PWM timer, and a watchdog timer. The Slope A/D converter provides a basic analog measurement path without requiring an external ADC — enough for thermistor or potentiometer readout in a control loop.
That means no last-time-buy scramble for repair stock or new-design qualification.
The MSP430F2131TDWR is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. Lead time and minimum order quantity vary by source and stock position — request a quote to get a firm delivery schedule for your required quantity.
No official cross-reference or second-source order code is listed for the MSP430F2131TDWR. A higher-density sibling in the MSP430F2131 base-number series — such as the MSP430F2132 — may share the same 20-SOIC pinout and 1.8–3.6V supply, but firmware changes are required to accommodate the different Flash and RAM sizes; cross-grade qualification is the buyer's responsibility before BOM insertion.
The MSP430F2131TDWR is listed at 16MHz maximum CPU clock, driven by the internal oscillator with no external crystal required for basic operation.
RoHS, REACH, and other standard compliance documentation are available through the TI product page for the MSP430F2131 base number; request the specific certificate pack at the time of your RFQ to confirm the exact status for this order code.
