Connectivity is limited to SPI and UART/USART — there is no I2C peripheral on this part, so designs needing I2C must bit-bang it on GPIO or choose a different MSP430 variant. The 11 general-purpose I/O pins are enough for a simple sensor interface with a few control lines.","metaTitle":"Texas Instruments MSP430AFE231IPWR 16-bit MCU, 12 MHz","metaDescription":"Texas Instruments MSP430AFE231IPWR 16-bit MCU, 12 MHz core, 8 KB Flash, 512 B RAM, one 24-bit sigma-delta ADC, SPI/UART, -40 to 85 °C, 24-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"12MHz","Series":"MSP430F2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"11","Core Processor":"MSP430 CPU16","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 1x24b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430AFE231","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"24-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9303","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7412554fb8cd23d208fe08bda354203.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430AFE231IPWR/alternatives.json"},"ai":{"faq":[{"question":"Does MSP430AFE231IPWR have I2C?","answer":"No, the listed connectivity interfaces are SPI and UART/USART only.
