For BOM planning, this removes the urgency of finding a drop-in substitute or stocking up on lifetime buys. The part is ROHS3 compliant. The 24 MHz clock rate is the CPUXV2's maximum operating frequency. At this speed, FRAM program memory requires no wait states, so instruction fetch cycles are deterministic—important for real-time control loops where jitter in execution time can upset timing margins. The 8 KB FRAM size (8K x 8) is enough for mid-complexity firmware: sensor calibration tables, communication protocol stacks, and state machines. The 1K x 8 SRAM covers stack, heap, and small data buffers. If your application needs more RAM for large packet buffers or extensive lookup tables, consider the higher-density siblings in the MSP430FR57xx family. The 17 I/O pins, combined with the internal oscillator, allow a minimal two-wire programming/debug interface (SBW) plus a handful of sensor or actuator lines—enough for a compact sensor node or a simple human-machine interface. ## Package and footprint: 24-VQFN with exposed pad Housed in a 24-VFQFN exposed-pad package (4x4 mm body, supplier device package 24-VQFN), the MSP430FR5732IRGET is a surface-mount device. The pad also provides a low-inductance ground return for the digital switching currents, which helps keep EMI under control.","metaTitle":"MSP430FR5732IRGET 16-bit MCU, 24 MHz, 8 KB FRAM, 24-VQFN","metaDescription":"Texas Instruments MSP430FR5732IRGET 16-bit MCU with 24 MHz CPUXV2 core, 8 KB FRAM, 1 KB SRAM, 17 I/O, I²C/SPI/UART, -40°C to 85°C.","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":"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":"17","Core Processor":"MSP430 CPUXV2","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5732","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"24-VQFN (4x4)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4000","priceTiers":[{"qty":1,"price":"$3.40000","currency":"USD"},{"qty":10,"price":"$3.05000","currency":"USD"},{"qty":25,"price":"$2.88360","currency":"USD"},{"qty":100,"price":"$2.49910","currency":"USD"},{"qty":250,"price":"$2.37096","currency":"USD"},{"qty":500,"price":"$2.12746","currency":"USD"},{"qty":1250,"price":"$1.79424","currency":"USD"},{"qty":2500,"price":"$1.70453","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/84fcf854a99053c6b845c00249f03a27.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5732IRGET/alternatives.json"},"ai":{"faq":[{"question":"Can MSP430FR5732IRGET be replaced by MSP430FR5732IRGER?","answer":"Yes, the MSP430FR5732IRGER is the same device in a different reel packaging option (Tape & Reel vs Cut Tape).
