FRAM writes nearly as fast as it reads, no erase cycle needed, and it holds data without a battery. ## Industrial temperature and LCD drive The built-in LCD driver is the feature that saves a segment-driver IC on the BOM — it drives the glass directly, which is why this part shows up in gas-pump displays, thermostat panels, and medical device readouts. 52 I/O give headroom for a keypad matrix plus a few sensors alongside the display. ## 56-TSSOP — can I swap it on site? The 56-TSSOP (6.10 mm wide) is a fine-pitch surface-mount package. It is not socket-friendly, so an on-site swap means hot air or a reflow station. ## Peripherals and connectivity On the communication side: I²C, SPI, UART/USART, plus IrDA and SCI. That covers the usual sensor bus (I²C), display or radio SPI, and debug UART. The internal oscillator means you can boot without an external crystal for most applications — saves a component and a PCB trace. The 8-channel 10-bit ADC is enough for reading potentiometers, thermistors, or current-sense resistors in a control panel.","metaTitle":"MSP430FR4133IG56R MCU, 16-bit, 16 MHz, 15.5 KB FRAM","metaDescription":"TI MSP430FR4133IG56R 16-bit MCU with 15.5 KB FRAM, 16 MHz, 2K x 8 RAM, LCD driver, 52 I/O, -40 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":"52","Core Processor":"MSP430 CPU16","Package / Case":"56-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":"56-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the lead time for MSP430FR4133IG56R?","answer":"Lead time is confirmed at quote time against your specific order quantity and target date.
