The 8.4 MHz CPU clock is enough to run the metrology firmware loop and update the segment LCD display without external components. Program memory is 8 KB of Flash, with 256 x 8 bytes of RAM for runtime data and calibration coefficients. The part includes a built-in LCD driver, brown-out reset, POR, PWM, and watchdog timer, plus SPI and UART serial interfaces for communication with a host processor or sub-meter radio module. ## Industrial temperature grade — outdoor enclosure ready No commercial-grade derating needed for a meter sitting in a sun-baked cabinet or a sub-zero climate. ## 64-LQFP package — PCB layout notes Housed in a 64-LQFP with a 10x10 mm body, surface-mount. The 14 general-purpose I/O pins are enough for tamper detection, relay drive, and status LEDs alongside the serial interface.","metaTitle":"TI MSP430FE423AIPMR 16-bit MCU, 8.4 MHz, 8 KB Flash","metaDescription":"Texas Instruments MSP430FE423AIPMR 16-bit MSP430 MCU with 8.4 MHz core, 8 KB Flash, 256 B RAM, three 16-bit sigma-delta ADCs, LCD driver, SPI/UART, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8.4MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"14","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 3x16b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FE423","Program Memory Size":"8KB (8K 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":"$3.6086","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3e86f0608be738ff49720aaab5ce471.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FE423AIPMR and MSP430FE423AIPM?","answer":"The difference is the packaging format. MSP430FE423AIPMR is supplied in Tape & Reel (TR), suitable for automated pick-and-place assembly. MSP430FE423AIPM is typically supplied in tube or tray packaging. The silicon, firmware, and pinout are identical."},{"question":"Can MSP430FE423AIPMR be used for energy metering?","answer":"Yes, this is the primary application. The three 16-bit sigma-delta ADCs are designed for simultaneous voltage and current sampling required in single-phase energy metering. The LCD driver can directly drive a segment display for power consumption readout. The MSP430x4xx series includes metrology-specific application notes and reference designs from TI."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FE423AIPMR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FE423AIPMR when reusing this data.
