The 2 KB of SRAM (2K x 8) handles runtime data. Clocked at 16 MHz, it keeps up with sensor polling, communication, and control loops in battery-powered or energy-harvesting designs. ## CapSense and connectivity in a 20-pin package With 15 I/O lines and integrated capacitive touch sensing (CapSense), this MCU can replace a separate touch controller in human-interface applications — think capacitive buttons, sliders, or proximity wake-up. The peripheral set includes a brown-out detect and reset, power-on reset, PWM, and watchdog timer, plus I²C, SPI, and UART serial interfaces. The 8-channel 10-bit ADC handles analog inputs like temperature or battery voltage. All of this fits in a 20-VQFN package with an exposed thermal pad (3.5x4.5 mm), which helps pull heat out in enclosed or warm environments. The supply range of 2.0 V to 3.6 V covers single-cell Li-ion, two-cell alkaline, or 3.3 V regulated rails. The internal oscillator keeps the clock running without an external crystal, saving two pins and a component. ## Lifecycle — still in active production For BOM planning that means no last-time-buy pressure and no forced redesign in the near term.","metaTitle":"Texas Instruments MSP430FR2522IRHLT 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430FR2522IRHLT 16-bit MCU with 16 MHz core, 7.5 KB FRAM, 2 KB RAM, 15 I/O, CapSense, industrial temp -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, Cap Sense, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"15","Core Processor":"MSP430 CPU16","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2522","Program Memory Size":"7.5KB (7.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-VQFN (3.5x4.5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f21fe6158b63331629df2d1dbda5439a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430FR2522IRHLT in this component family?","answer":"Within the MSP430FR252x family, the MSP430FR2522 is the base product number, and the IRHLT suffix denotes the 20-VQFN package and -40 to 85°C temperature range.
