At 8 MHz the CPUX core executes most instructions in a single cycle. ## Peripherals that save external components Beyond the LCD driver, the peripheral set includes a DMA controller for moving data without CPU intervention, a brown-out reset and power-on reset supervisor, a PWM timer, and a watchdog timer.","metaTitle":"TI MSP430F46191IPZR 16-bit MCU, 8MHz, 120KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F46191IPZR 16-bit MCU with MSP430 CPUX core at 8MHz, 120KB Flash, 4KB RAM, LCD driver, 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":"8MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"80","Core Processor":"MSP430 CPUX","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F46191","Program Memory Size":"120KB (120K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.4761","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1fcea670b9343edbca2b2bc7659e99b7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F46191IPZR/alternatives.json"},"ai":{"faq":[{"question":"What is MSP430F46191IPZR's listed speed?","answer":"The core runs at 8 MHz, which yields roughly 8 MIPS for single-cycle instructions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F46191IPZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F46191IPZR when reusing this data.
