The 2.5 KB RAM handles moderate data buffers and stack depth; if your application runs multiple communication stacks or large lookup tables, budget the RAM headroom before committing the BOM line. The part integrates a brown-out detect and reset, power-on reset, PWM timer, watchdog timer, and a direct LCD driver — the LCD controller is a distinguishing feature in this MCU class, saving an external display driver IC and its associated board area.","metaTitle":"TI MSP430A149IPZR 16-bit MCU, 16 MHz, 60 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430A149IPZR 16-bit MCU, 16 MHz core, 60 KB Flash, 2.5 KB RAM, industrial temp -40°C to 85°C, 100-LQFP.","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":"MSP430x4xx","Package":"Tape & Reel (TR)","RAM Size":"2.5K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"MSP430","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 3x16b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430A149","Program Memory Size":"60KB (60K 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":"$6.8818","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cdba3a4c01690c941d2905afb361b46a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430A149IPZR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430A149IPZR and MSP430A149IPZT?","answer":"The difference is the shipping medium: the MSP430A149IPZR ships in Tape & Reel (TR), while the MSP430A149IPZT ships in a tray (Tray).
