On-chip SRAM is 1 KB. The device integrates 16 general-purpose I/O lines, a 10-bit ADC with 8 channels, and serial interfaces including I²C, SPI, and UART. ## FRAM vs Flash: what the memory choice means The 3.75 KB FRAM program memory is the standout feature. Unlike Flash, FRAM writes at bus speed without needing a pre-erase cycle, and it endures orders of magnitude more write cycles — typically 10^15 vs 10^4–10^5 for Flash. For a firmware engineer, this means you can treat the program space almost like RAM: update calibration tables, log fault codes, or store configuration data directly in the same memory array without wear-leveling or sector-erase delays. The trade-off is density: 3.75 KB is tight for complex applications, so this part targets single-function control loops or simple sensor nodes rather than feature-rich firmware. The base part number MSP430FR2311 shares the same active status across its package variants. The device is supplied in a 20-lead TSSOP (4.40 mm width) with a surface-mount footprint. The 16 I/O pins include the ADC inputs and serial interface pins, so pin allocation needs to be planned early in the schematic — there is no second function mux on every pin.","metaTitle":"MSP430FR2311IPW20R 16-bit MCU, 16 MHz, 3.75 KB FRAM","metaDescription":"Texas Instruments MSP430FR2311IPW20R 16-bit MCU with 16 MHz core, 3.75 KB FRAM, 1 KB SRAM, 16 I/O, -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":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","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)","Product Status":"Active","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":"$1.9000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f54bef595f6c353e931fcbdbed65c27e.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2311IPW20R","citationPolicyUrl":"https://icboms.com/llms.txt","lastUpdated":"2026-07-17T19:50:00.618Z","lastPublished":"2026-07-17T19:50:00.618Z","indexable":true}}
