Each converter runs independently, allowing simultaneous sampling of three analog channels — critical for polyphase energy metering where voltage and current on each phase must be captured at the same instant. The 16-bit resolution gives 96 dB of dynamic range, enough to resolve microvolt-level signals from shunt resistors or current transformers without an external amplifier. For a design targeting Class 1 or Class 0.5 energy meters, this ADC block eliminates the separate AFE (analog front-end) IC, saving BOM cost and board area. ## Peripheral set and connectivity for instrumentation Beyond the ADCs, the peripheral set includes a brown-out detect/reset (BOR), power-on reset (POR), a watchdog timer (WDT), PWM outputs, and an LCD driver — the LCD segment drive is a legacy MSP430x4xx strength for direct glass connection without an external display controller. Connectivity covers SPI and UART/USART, sufficient for communicating with an external EEPROM, RF module, or host processor. With 14 general-purpose I/O pins in the 64-LQFP package, there is enough headroom for a few pushbuttons, LED indicators, and a serial debug interface alongside the analog inputs. The 1.8V to 3.6V supply range means it can run directly from two alkaline cells, a single Li-ion, or a regulated 3.3V rail — no extra LDO needed if the battery voltage stays above 1.8V.","metaTitle":"TI MSP430F427AIPMR 16-bit MCU, 32KB Flash, 3x16-bit ADC","metaDescription":"Texas Instruments MSP430F427AIPMR 16-bit MCU with 32KB Flash, 1K x 8 RAM, 3x16-bit sigma-delta ADC, 8MHz core, -40 to 85°C, 64-LQFP.","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":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"1K 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":"MSP430F427","Program Memory Size":"32KB (32K 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":"$8.3400","priceTiers":[{"qty":1,"price":"$8.34000","currency":"USD"},{"qty":10,"price":"$7.53400","currency":"USD"},{"qty":25,"price":"$7.18320","currency":"USD"},{"qty":100,"price":"$6.23710","currency":"USD"},{"qty":250,"price":"$5.95680","currency":"USD"},{"qty":500,"price":"$5.43120","currency":"USD"},{"qty":1000,"price":"$4.73040","currency":"USD"},{"qty":2000,"price":"$4.55520","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f2d862a9e83d8a40a4b8422a2c4b869.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F427AIPMR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F427AIPMR RoHS compliant?","answer":"Yes, the MSP430F427AIPMR is listed as ROHS3 Compliant."},{"question":"How to program MSP430F427AIPMR?","answer":"The MSP430F427AIPMR is programmed via the Spy-Bi-Wire (SBW) or JTAG interface using TI's standard MSP430 programming tools — the MSP-FET or MSP-GANG.

However, it is not a pin-compatible second source — the MSP430F427AIPMR is a 16-bit ultra-low-power part with three 16-bit sigma-delta ADCs and LCD drive, targeting metering and precision analog, while the F280041 targets real-time control with a 32-bit DSP core. The choice depends on whether the application needs the sigma-delta ADC precision (MSP430) or higher math throughput and CAN."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F427AIPMR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F427AIPMR when reusing this data.
