This means you can treat the FRAM as both program store and data-logging space without worrying about wear-leveling or sector erase times. The part also carries 1K x 8 of SRAM for stack and variables. ## Package and mounting — 38-TSSOP Housed in a 38-pin TSSOP with 0.240\" body width and 0.65 mm pitch, surface-mount only. The supplier device package is 38-TSSOP. No exposed pad — thermal dissipation is through the leads, so keep the copper pours generous if running the ADC or PWM at high duty cycles near the top of the temperature range. ## Lifecycle and sourcing This part is current-production and available through independent distribution.","metaTitle":"TI MSP430FR5739IDAR 16-bit MCU, 24 MHz, 16 KB FRAM, 38-TSSOP","metaDescription":"Active 16-bit MSP430 MCU with 24 MHz core, 16 KB FRAM, 1K x 8 SRAM, 30 I/O, I²C/SPI/UART, -40°C 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":"24MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 14x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5739","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/76209ce250d2dd14ce4abf769291b523.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430FR5739IDAR obsolete or end-of-life?","answer":"No — the manufacturer lists it as Active.
