The device also includes 2K x 8 of SRAM for stack and scratchpad use. ## Peripheral set and connectivity On-chip peripherals include a brown-out detect, DMA controller, POR, PWM timer, and watchdog timer. Twelve 12-bit ADC channels handle analog inputs without an external converter. ## 64-VQFN package — rework and layout notes The pad also serves as a ground return. During rework, preheat the board to 125°C and use a hot-air profile that ramps slowly to avoid lifting the pad — the exposed paddle wicks heat fast. No last-time-buy or substitution risk for current designs.","metaTitle":"TI MSP430FR5889IRGCT 16-bit MCU, 128KB FRAM, 16MHz, 64-VQFN","metaDescription":"Texas Instruments MSP430FR5889IRGCT 16-bit MCU with 128KB FRAM, 16MHz CPUXV2 core, 48 I/O, I2C/SPI/UART, -40 to 85°C, 64-VQFN.","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, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5889","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-VQFN (9x9)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.0600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2b670fee89d13c5844b8166b8ab0bce.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430FR5889IRGCT support I2C and SPI?","answer":"Yes, the connectivity block includes I²C and SPI interfaces, along with IrDA, SCI, and UART/USART.
