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. 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","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/76209ce250d2dd14ce4abf769291b523.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5739IDAR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430FR5739IDAR obsolete or end-of-life?","answer":"No — the manufacturer lists it as Active.
