The CPUXV2 is a 16-bit RISC architecture with a hardware multiplier, so metrology algorithms like active/reactive power and RMS calculations run in a deterministic number of cycles. For a three-phase meter reading voltage and current on each phase plus neutral, the 25 MHz headroom means the firmware can complete the DSP chain within the line-cycle window. ## Seven 24-bit sigma-delta ADCs — the metrology engine Seven 24-bit sigma-delta converters sample voltage and current channels simultaneously for polyphase energy meters. For a procurement team qualifying this part into a new meter design, there is no imminent supply discontinuity. The base product number MSP430F67771 covers a range of Flash and RAM options in the same 128-LQFP footprint, so if a future firmware revision needs more memory, a pin-compatible migration within the family is possible without a board spin.","metaTitle":"Texas Instruments MSP430F67771IPEUR 16-bit MCU, 25 MHz","metaDescription":"TI MSP430F67771IPEUR 16-bit MCU with MSP430 CPUXV2 at 25 MHz, 256 KB Flash, 32K x 8 RAM, 7x24b sigma-delta ADCs, 90 I/O, 128-LQFP, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 7x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"90","Core Processor":"MSP430 CPUXV2","Package / Case":"128-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67771","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"128-LQFP (20x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.3836","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/278d335c2651ecd2b8be3b6ed55b7d99.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to MSP430F67771IPEUR in the same family?","answer":"Within the MSP430F67771 family, the base product number covers multiple Flash and RAM density options in the same 128-LQFP footprint. The MSP430F67771IPEUR is the 256 KB Flash / 32K x 8 RAM variant. Higher-density siblings like the MSP430F67791 offer 512 KB Flash and 64K x 8 RAM, while lower-density options such as the MSP430F67751 provide 128 KB Flash. All share the same seven 24-bit sigma-delta ADC block and peripheral set, so firmware migration is straightforward if the memory budget changes."},{"question":"Does MSP430F67771IPEUR support metering applications?","answer":"Yes, this MCU is specifically designed for polyphase energy metering. The seven 24-bit sigma-delta ADCs enable simultaneous sampling of voltage and current on up to four channels (three phases plus neutral), and the 25 MHz CPUXV2 core has the throughput for real-time energy calculation. The integrated LCD driver can directly drive a segment display for meter readout, and the serial interfaces support communication with a host system or smart-grid module."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67771IPEUR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67771IPEUR when reusing this data.
