That makes it a direct replacement for designs that previously needed separate Flash and EEPROM, or that relied on battery-backed SRAM for data logging. On-chip SRAM is 1K x 8, enough for small stacks and temporary buffers. The part integrates a 12-channel 12-bit ADC, a brown-out reset, POR, DMA, PWM, and a watchdog timer. Connectivity covers I²C, IrDA, SCI, SPI, and UART/USART. With 31 general-purpose I/O lines and an internal oscillator, it can run a sensor node or control loop without external clock components. ## FRAM memory: why it changes the firmware and data-storage strategy The 32 KB FRAM program memory is the headline feature. Unlike Flash, FRAM writes at bus speed with no erase-before-write penalty, and it draws microamps during a write cycle rather than milliamps. For a battery-powered data logger, that means you can store sensor readings to non-volatile memory on every sample without wearing out the memory or draining the cell. The 1K x 8 SRAM is modest — plan to use FRAM for both code and variable storage, keeping the SRAM for stack and interrupt context. The FRAM endurance is effectively unlimited for field updates, so over-the-air firmware upgrades are practical without worrying about sector wear. The 38-TSSOP package (0.240\" body width, 6.10 mm wide) is a fine-pitch surface-mount footprint — standard for automated assembly, but the 0.5 mm lead pitch means the reflow profile needs care to avoid solder bridges. ## Lifecycle and sourcing posture For a BOM line, this part presents no imminent supply risk. The base product number is MSP430FR5957, and the series is MSP430 FRAM.","metaTitle":"TI MSP430FR5957IDA 16-bit MCU, 16 MHz, 32 KB FRAM, 38-TSSOP","metaDescription":"Texas Instruments MSP430FR5957IDA 16-bit MCU with 16 MHz CPU, 32 KB FRAM, 1K x 8 SRAM, 31 I/O, 12x12b ADC, I²C/SPI/UART, -40°C to 85°C, 38-TSSOP.","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":"Tube","RAM Size":"1K 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":"MSP430FR5957","Program Memory Size":"32KB (32K 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":"$4.2447","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b4ff231ab172f4b122f04a9e54765b3.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5957IDA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5957IDA when reusing this data.
