The headline here is the 512B FRAM program memory — it writes at bus speed without the page-erase penalty of Flash, and it unifies code and data storage so a single memory space serves both. For a sensor node or control loop that logs calibration constants or runtime counters, FRAM eliminates the EEPROM emulation layer and the wear-leveling logic that Flash demands. The 512 x 8 RAM is modest — enough for a super-loop scheduler or a small state machine, but a full RTOS with multiple stacks will exhaust it before the code space does. The 12 I/O count means each pin needs a clear assignment early in the schematic; there is no room for unused pins to float. ## Package and board-fit: 24-VFQFN with exposed pad A 3.3 V rail is the obvious choice, but the low end lets the part run from a 2xAA battery stack down to near-depletion without a boost converter. ## Peripherals and connectivity for sensor-node designs The PWM output is useful for driving a LED indicator or a small piezo buzzer directly. Serial connectivity covers IrDA, SCI, SPI, and UART/USART. The SPI and UART are the workhorses for external sensors (temperature, humidity, pressure) and short-range radios. The IrDA module is present but rarely used in new designs — it adds no pin cost since it shares the UART pins. ## Active production and compliance posture ROHS3 compliance is confirmed, covering all six original substances plus the four phthalates, with no exemption-based carve-outs.","metaTitle":"TI MSP430FR2000IRLLT 16-bit MCU, 512B FRAM, 16 MHz, 24-VQFN","metaDescription":"Texas Instruments MSP430FR2000IRLLT 16-bit MCU with 512B FRAM, 16 MHz CPU16 core, 12 I/O, 1.8-3.6V supply, -40 to 85°C, 24-VFQFN.

Firmware updates must be done via a debug interface (SBW/JTAG) that writes directly to FRAM, or the device must be pre-programmed before assembly. The advantage of FRAM is that writes are fast and wear-free, so repeated field updates via a wired debug connection are viable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2000IRLLT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR2000IRLLT when reusing this data.
