That means you can log sensor data or store calibration constants directly in program space without wearing out sectors — no EEPROM emulation or external serial memory needed. The 10-channel 12-bit ADC and four 12-bit DAC channels handle analog front-end tasks on-chip, reducing external component count for closed-loop control or multi-sensor acquisition. ## Connectivity and peripherals — what is on the bus On-chip peripherals include a brown-out detect, POR, PWM outputs, and a watchdog timer — enough to build a standalone controller without external supervisor ICs. TI lists the MSP430FR2355TDBT as Active. The base product number MSP430FR2355 indicates a family with multiple density and package variants, so if a future redesign needs more memory or a different footprint, there is a pin-compatible migration path within the same series without a PCB respin.","metaTitle":"MSP430FR2355TDBT Texas Instruments 16-bit MCU, 24MHz","metaDescription":"MSP430FR2355TDBT 16-bit MCU with 24MHz core, 32KB FRAM, 4K x 8 RAM, 34 I/O, 10x12b ADC, 4x12b DAC, -40°C~105°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":"Tube","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"34","Core Processor":"MSP430 CPU16","Package / Case":"38-TFSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2355","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5b2b725f8ceff8dabb22c56965f52827.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430FR2355TDBT in this component family?","answer":"Within the MSP430FR2355 series, devices with the same 38-TSSOP footprint and pinout — such as the MSP430FR2355TPT — share the same package and peripheral set.
