The 3.75 KB program space is also usable for non-volatile data storage — config parameters, calibration constants, or logging counters — without wearing out the memory. Combined with 1 KB SRAM, the memory budget fits small control loops, state machines, and data-logging firmware that does not exceed a few thousand lines of C. ## Active lifecycle — no near-term EOL concern The part is suitable for both new design-in and ongoing production. For dual-sourcing or supply resilience, the MSP430 FRAM family includes pin-compatible density variants — the base product number MSP430FR2311 identifies this specific memory and peripheral configuration. ## 20-TSSOP — footprint and layout notes The 16 I/O lines are accessible on both sides of the body. Decoupling should follow the usual ceramic per supply pin, placed close to the package.","metaTitle":"TI MSP430FR2311IPW20 16-bit MCU, 16 MHz, 3.75 KB FRAM","metaDescription":"Texas Instruments MSP430FR2311IPW20 16-bit MCU with 16 MHz CPU, 3.75 KB FRAM, 1 KB SRAM, 8x10b ADC, I²C/SPI/UART, -40 to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"16MHz","title":"MSP430FR2311IPW20","Series":"MSP430™ FRAM","Package":"Tray","RAM Size":"1K x 8","Core Size":"16-Bit","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2311","Program Memory Size":"3.75KB (3.75K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f54bef595f6c353e931fcbdbed65c27e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What replaces the MSP430FR2311IPW20?","answer":"The natural successor is the MSP430FR2355 in TSSOP-20, which is pin-compatible and steps up to 32KB FRAM.
