Its defining hardware feature is the six 16-bit sigma-delta analog-to-digital converters — a configuration that maps directly to polyphase energy metering, where each phase and neutral current needs its own simultaneous sampling channel. ## 92 KB Flash and 4K x 8 RAM — sizing the firmware budget The Flash is enough to hold a full metrology algorithm, calibration constants, and a Modbus or M-Bus protocol stack without external memory. The 4K x 8 RAM handles real-time data buffers for the six ADC channels and the LCD controller (the peripheral set includes LCD drive capability). ## Package and I/O count Housed in a 100-pin LQFP (14x14 mm body), the MSP430F47166IPZR brings out 68 general-purpose I/Os. The LQFP package is hand-solderable for prototypes and reflow-compatible for production. The 100-pin count provides enough headroom for connecting the six ADC inputs, an LCD segment driver, and the serial communication interfaces simultaneously.","metaTitle":"Texas Instruments MSP430F47166IPZR 16-Bit MCU, 92KB Flash","metaDescription":"Texas Instruments MSP430F47166IPZR 16-bit MCU with 16MHz core, 92KB Flash, 4K x 8 RAM, six 16-bit sigma-delta ADCs, industrial temp range.","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); 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, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"68","Core Processor":"MSP430 CPU16","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 6x16b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F47166","Program Memory Size":"92KB (92K x 8)","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":"$9.4419","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/029b166e60e2cfc41cdca24e57001410.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F47166IPZR/alternatives.json"},"ai":{"faq":[{"question":"Are there any direct replacements or equivalents for MSP430F47166IPZR?","answer":"Pin-compatible alternatives exist within the MSP430F471xx family in the same 100-LQFP package — for example, the MSP430F47197 offers more Flash and RAM while keeping the same six 16-bit ADC peripheral set.
