The 2K x 8 SRAM handles the runtime stack and buffer, while the integrated 12-bit ADC with 12 channels samples analog inputs directly. ## Supply rail and temperature — where this MCU lives on the board The supply range runs from 1.8 V up to 3.6 V, so you can run it straight off a single Li-ion cell or a regulated 3.3 V rail without an extra LDO. ## Peripherals and connectivity — what the 31 I/O pins give you With 31 I/O lines, this MCU has room for a keypad, a small character LCD, and a handful of sensors. Brown-out reset, power-on reset, and a watchdog timer are all on-chip, so external supervisor ICs are optional.","metaTitle":"MSP430FR5959IDAR 16-bit MCU, 64KB FRAM, 16 MHz, 38-TSSOP","metaDescription":"Texas Instruments MSP430FR5959IDAR 16-bit MCU with 64KB FRAM, 2K x 8 SRAM, 16 MHz CPUXV2 core, 12-bit ADC, 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":"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":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5959","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1601","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4ff231ab172f4b122f04a9e54765b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430FR5959IDAR have I²C and SPI interfaces?","answer":"The 31 I/O pins are shared among these peripherals."},{"question":"What is the core processor of MSP430FR5959IDAR?","answer":"The core is the MSP430 CPUXV2, a 16-bit RISC processor clocked at 16 MHz.
