At this speed the part draws roughly 250 µA/MIPS in active mode, which is the trade-off: you get enough throughput for a 1 kHz control loop with sensor reads and a UART comms task, but not the 100+ MIPS of a Cortex-M4. For designs that only need to poll a sensor every 100 ms and wake on an interrupt, the MSP430's five low-power modes let the core sleep at sub-µA levels and wake in under 1 µs. That is where this part earns its keep versus a higher-clocked part that burns standby current just keeping the PLL alive. ## 20-TSSOP footprint and supply rails The 20-TSSOP package (4.40 mm wide, 0.65 mm pitch) is a common surface-mount footprint that routes easily on a two-layer board. 16 general-purpose I/O are available in this package — enough for a few sensor inputs, a PWM output, and a UART or SPI bus.","metaTitle":"Texas Instruments MSP430F2131IPWR MCU","metaDescription":"Texas Instruments MSP430F2131IPWR 16-bit MCU, 8KB Flash, 256B RAM, 16MHz, 1.8V-3.6V, -40°C to 85°C, 20-TSSOP.

The MSP430F2xx family includes higher-density Flash variants (e.g., MSP430F2418 with 48 KB Flash) in different pin counts, but those are not drop-in replacements. For a pin-compatible upgrade path within the same 20-TSSOP footprint, verify with the factory or your TI representative. The F280041PZQR from the C2000 family is a different architecture (32-bit C28x at 100 MHz) and is not a functional second-source — it targets a different performance tier."},{"question":"What is MSP430F2131IPWR's listed speed?","answer":"The MSP430F2131IPWR is rated for a 16 MHz core clock speed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F2131IPWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F2131IPWR when reusing this data.
