The I²C, SPI, UART, and LINbus connectivity covers both local sensor buses and vehicle network interfaces — the LIN physical layer is integrated, so a LIN transceiver is the only external component needed for an automotive sub-node. Thirty GPIOs in the 38-TSSOP package leave enough headroom for a small keypad or a parallel LCD after allocating the serial peripherals. ## Industrial temperature range and on-chip supervision The integrated brown-out reset, power-on reset, and watchdog timer eliminate three external ICs from the BOM: the BOR holds the core in reset until the supply crosses the threshold, the POR ensures known startup state, and the WDT guards against firmware lockups without a separate supervisor. ## Active production — sourcing posture The base product number MSP430FR5729 covers the full family variant — the IDA suffix denotes the 38-TSSOP package and industrial temperature grade. ## Package footprint notes for layout The 38-TSSOP package has a 0.65 mm lead pitch and a 6.10 mm body width — the footprint fits on a two-layer board with 0.25 mm trace widths and 0.30 mm via drill. The supplier device package designation 38-TSSOP matches the standard JEDEC MO-153 profile; no exposed thermal pad, so the ground slug is not a requirement. Surface-mount assembly with standard reflow profile per IPC/JEDEC J-STD-020.","metaTitle":"TI MSP430FR5729IDA MCU, 16-bit 8MHz, 16KB FRAM, 38-TSSOP","metaDescription":"Texas Instruments MSP430FR5729IDA 16-bit MCU, 8MHz, 16KB FRAM, 1KB RAM, 14ch 10-bit ADC, 30 I/O, I²C/SPI/UART, -40°C to +85°C, 38-TSSOP.","metaKeywords":null},"attributes":{"series":"MSP430™ FRAM","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430™ FRAM","Package":"Tube","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":"MSP430FR5729","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":"$4.3900","priceTiers":[{"qty":1,"price":"$4.39000","currency":"USD"},{"qty":10,"price":"$3.94700","currency":"USD"},{"qty":25,"price":"$3.73160","currency":"USD"},{"qty":100,"price":"$3.23390","currency":"USD"},{"qty":250,"price":"$3.06808","currency":"USD"},{"qty":500,"price":"$2.75298","currency":"USD"},{"qty":1000,"price":"$2.32179","currency":"USD"},{"qty":2500,"price":"$2.20570","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fd8cd96c9714684c7d1b8b7e2da4f1f1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5729IDA/alternatives.json"},"ai":{"faq":[{"question":"What is the program memory type and size on the MSP430FR5729IDA?","answer":"It has 16 KB of FRAM (ferroelectric RAM) program memory — FRAM combines the non-volatility of flash with write speeds comparable to SRAM and endurance of 10^15 cycles, so firmware updates incur no erase delay and the memory does not wear out."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5729IDA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5729IDA when reusing this data.
