This saves board area, reduces component count, and simplifies the interconnect — the display connects straight to the MCU pins without an external charge pump or bias generator in most cases. The peripheral handles the common and segment waveforms in hardware, so the firmware only writes display data to a buffer. For a panel-meter or blood-glucose-monitor design, this peripheral alone can justify the part selection over a general-purpose MCU that needs an external display driver. ## Three 16-bit sigma-delta ADCs — simultaneous multi-channel sampling Three independent 16-bit sigma-delta ADCs allow the MSP430F423AIPM to sample three analog channels simultaneously, each with its own programmable gain amplifier and digital filter. This is the key spec for energy metering (voltage and current per phase) or multi-sensor data acquisition where phase alignment between channels matters. Each converter runs independently, so the firmware can trigger a conversion on one channel without disturbing the others. The 16-bit resolution provides a theoretical dynamic range of about 96 dB, sufficient for most industrial sensor interfaces without an external ADC. TI continues to support the MSP430x4xx family with development tools, application notes, and firmware libraries. ## Supply range and I/O — battery-friendly and flexible The 14 general-purpose I/O pins are 5 V tolerant on most MSP430 devices, though the evidence does not specify tolerance here — verify against the datasheet I/O structures for the specific pin.","metaTitle":"TI MSP430F423AIPM 16-bit MCU, 8 MHz, 8 KB Flash, 64-LQFP","metaDescription":"Texas Instruments MSP430F423AIPM 16-bit MCU with 8 MHz core, 8 KB Flash, 256 B RAM, integrated LCD driver, three 16-bit ADCs, SPI/UART, 1.8-3.6 V, -40°C to","metaKeywords":null},"attributes":{"series":"MSP430x4xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x4xx","Package":"Tray","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":"MSP430F423","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":"$7.3600","priceTiers":[{"qty":1,"price":"$7.36000","currency":"USD"},{"qty":10,"price":"$6.65100","currency":"USD"},{"qty":25,"price":"$6.34200","currency":"USD"},{"qty":160,"price":"$5.50663","currency":"USD"},{"qty":320,"price":"$5.25913","currency":"USD"},{"qty":480,"price":"$4.79508","currency":"USD"},{"qty":960,"price":"$4.17636","currency":"USD"},{"qty":2400,"price":"$4.02168","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f2d862a9e83d8a40a4b8422a2c4b869.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F423AIPM/alternatives.json"},"ai":{"faq":[{"question":"What programming tool is needed for MSP430F423AIPM?","answer":"Texas Instruments offers the MSP-FET programmer/debugger and the MSP-GANG production programmer.
