The part also integrates a segment LCD driver with an internal charge pump, so a glass LCD panel connects directly to the MCU pins — no separate display controller IC needed. ## 16 MHz core — enough for the job, not for number crunching The 16 MHz clock is modest by today's MCU standards, but this part isn't aiming at the performance tier. It's sized for control-loop and user-interface tasks where the FRAM's fast writes and the LCD driver's low overhead matter more. At 16 MHz the CPU can service a UART at 115200 baud, poll an ADC channel, and update a segment LCD in the same interrupt cycle without timing pressure. ## Package and footprint — 48-TSSOP with 0.5 mm pitch The 48-TSSOP package (6.10 mm body width, 0.5 mm lead pitch) is a fine-pitch surface-mount part. The PCB land pattern needs a solder-mask-defined pad with a stencil aperture sized for 0.5 mm pitch to avoid bridging. The supplier device package is 48-TSSOP, so footprint compatibility across the MSP430FR4133 family is consistent — the IG48 and IPM variants share the same pad layout. ## Industrial temperature grade — where it runs and where it doesn't It covers factory automation, outdoor telecom cabinets, automotive cabin (non-engine-bay), and commercial HVAC. The FRAM family is a current TI portfolio focus, so long-term supply looks stable — but as with any sole-sourced MCU, qualifying a backup variant (e.g., the MSP430FR4133IPM in a different package) for dual-sourcing is worth the engineering effort if the BOM volume justifies it.","metaTitle":"TI MSP430FR4133IG48 16-bit MCU, 16 MHz, 15.5 KB FRAM","metaDescription":"Texas Instruments MSP430FR4133IG48 16-bit MCU with 16 MHz CPU, 15.5 KB FRAM, 2 KB SRAM, integrated LCD driver, 8x10-bit ADC, 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":"Tube","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":"$3.7100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dbbf23a4e60ee594de5e0dd102bb2969.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR4133IG48 and MSP430FR4133IPM?","answer":"The IG48 suffix indicates a 48-TSSOP package (0.5 mm pitch), while the IPM suffix indicates a 64-LQFP package (0.5 mm pitch). The IG48 has 44 I/O; the IPM variant offers more I/O due to the larger package. Core, memory, and peripheral sets are identical. The choice is driven by board area and I/O count requirements — the IG48 is the smaller footprint option."},{"question":"How to program the MSP430FR4133IG48?","answer":"Programming is done through the Spy-Bi-Wire (SBW) two-wire JTAG interface, which is pin-compatible with TI's MSP-FET or eZ-FET debug probes. TI's Code Composer Studio or IAR Embedded Workbench supports the MSP430FR4133. The FRAM can be programmed in-system at full speed without the erase cycle required by Flash MCUs."},{"question":"Is MSP430FR4133IG48 RoHS compliant?","answer":"The evidence does not explicitly state RoHS compliance status. TI typically marks RoHS-compliant devices with a 'G4' suffix or similar indicator.
