The 48 I/O lines, SPI and UART/USART connectivity, plus internal oscillator cover a lot of sensor-node and control-loop designs without needing external clock parts. The Slope A/D converter is a distinguishing feature — it's a single-slope type, not a SAR or sigma-delta, so factor that into your analog front-end plan if you need precise multi-channel conversions.","metaTitle":"Texas Instruments MSP430F1491IPMR 16-Bit MCU, 60KB Flash","metaDescription":"Texas Instruments MSP430F1491IPMR 16-bit MCU with 60KB Flash, 2K x 8 RAM, 8MHz core, 48 I/O, SPI/UART, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"MSP430x1xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F1491","Program Memory Size":"60KB (60K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.9700","priceTiers":[{"qty":1,"price":"$15.97000","currency":"USD"},{"qty":10,"price":"$14.67400","currency":"USD"},{"qty":25,"price":"$14.06600","currency":"USD"},{"qty":100,"price":"$12.39320","currency":"USD"},{"qty":250,"price":"$11.78496","currency":"USD"},{"qty":500,"price":"$11.02464","currency":"USD"},{"qty":1000,"price":"$10.11226","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2aa7acdd7480e3bd3263b4c69f43f618.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F1491IPMR/alternatives.json"},"ai":{"faq":[{"question":"How to program MSP430F1491IPMR?","answer":"The MSP430F1491IPMR uses the standard MSP430 JTAG/SBW (Spy-Bi-Wire) interface for programming and debug.
