The 12K x 8 RAM gives it room for buffered ADC samples or protocol stacks without spilling to FRAM. ## 44 I/O and 9x12b ADC — peripheral mix for sensor-heavy designs With 44 I/O lines and a 9-channel 12-bit SAR ADC, this part can handle a sensor array plus a display or keypad without needing an external mux or GPIO expander. The connectivity set — IrDA, SCI, SPI, UART/USART — covers the common serial links for modems, RF modules, and wired interfaces. Brown-out detect and POR are integrated, so you can skip the external supervisor on cost-sensitive boards. ## 64-VQFN package — what the layout engineer needs to know The 0.5 mm pitch calls for a fine-pitch stencil and careful solder paste volume; it is not a hand-solder part for field repair, but a rework station with hot air can swap it if the board has a thermal relief pattern. ## Supply range and power profile The FRAM's near-zero standby power means the MCU can sit in a low-power mode drawing microamps while retaining all program and data — no need to shadow FRAM to RAM on wake. This is the part you pick when the battery has to last years, not months.","metaTitle":"Texas Instruments MSP430FR5043IRGCR MCU, 16-Bit, 16MHz","metaDescription":"Texas Instruments MSP430FR5043IRGCR 16-bit MCU with 64KB FRAM, 12K x 8 RAM, 16MHz core, 44 I/O, 9x12b ADC, -40°C to 85°C.

Pin-compatible siblings with different memory sizes or peripheral sets exist within the same series, but the exact alternative depends on your required FRAM size, RAM, and ADC channel count. The base product number MSP430FR5043 is the anchor for this variant."},{"question":"What does the 16 MHz core speed mean for real-time sensing tasks?","answer":"The 16 MHz clock is enough to run a 12-bit SAR ADC conversion, process the result, and log it to FRAM within a few microseconds. For metering or sensor polling loops that run at 1 kHz or slower, the core spends most of its time in low-power sleep — the speed is there for burst processing when needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5043IRGCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5043IRGCR when reusing this data.
