The 2K x 8 RAM is the volatile scratchpad for stack and variables; the FRAM reduces RAM pressure because calibration constants and state tables can live in program space and be updated in-place. The 16 MHz core speed sets the throughput ceiling for the MSP430 CPU16 — enough for real-time capacitive touch scanning (Cap Sense peripheral,) and PWM generation for LED dimming or motor control, but not for heavy DSP or floating-point math. ## Package, I/O, and supply — the board-fit constraints The 11 I/O lines must cover the sensor inputs, display interface, and any serial bus; with I²C, SPI, and UART on-chip, two or three pins get consumed by the bus, leaving 8-9 for discrete signals. Supply range is 2V to 3.6V — this maps to a single-cell Li-ion (3.0-4.2V) or two alkaline cells (2.4-3.0V) without a regulator. The internal oscillator saves the external crystal for applications that can tolerate the ±1-2% accuracy of the on-chip RC. Industrial temperature grade -40°C to 85°C covers outdoor enclosures, factory-floor panels, and under-hood auxiliary modules — the FRAM retains data across the full range without refresh. ## Active lifecycle and sourcing posture ROHS3 compliant. The base product number is MSP430FR2522, which covers the whole family variant matrix. No stock-holding claim — lead time is per-RFQ.","metaTitle":"TI MSP430FR2522IPW16 MCU, 16MHz, 7.5KB FRAM, 16-TSSOP","metaDescription":"Texas Instruments MSP430FR2522IPW16 16-bit MCU with 7.5KB FRAM, 16MHz core, 2Kx8 RAM, 11 I/O, I²C/SPI/UART, -40°C to 85°C.
