That makes it a strong pick for data-logging, metering, or any application where the firmware needs to update calibration constants or configuration tables in the field without wearing out the memory. ## Package and supply — board-fit notes Housed in a 48-TSSOP (6.10 mm wide, 0.240\" pitch), surface-mount only. Internal oscillator means no external crystal needed for basic clocking, though the internal oscillator type is sufficient for most UART and SPI timing. ## Lifecycle — no LTB worry Listed as Active in production.","metaTitle":"MSP430FR4133IG48R 16-bit MCU, 16 MHz, 15.5 KB FRAM, 48-TSSOP","metaDescription":"Texas Instruments MSP430FR4133IG48R 16-bit MCU with 16 MHz CPU, 15.5 KB FRAM, 2 KB SRAM, 44 I/O, I2C/SPI/UART, industrial temp -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, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"44","Core Processor":"MSP430 CPU16","Package / Case":"48-TFSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR4133","Program Memory Size":"15.5KB (15.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5746","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430FR4133IG48R support I2C and SPI?","answer":"Yes."},{"question":"Where can I find the datasheet for MSP430FR4133IG48R?","answer":"The datasheet is available from Texas Instruments under the base product number MSP430FR4133.
