For new designs, a pin-compatible alternative within the MSP430F6xx family should be evaluated; the 512 KB Flash and 6x24-bit Σ-Δ ADC peripheral set is specific to this metering-oriented variant. ## Core and memory – 25 MHz, 512 KB Flash, 32 KB RAM That Flash density is generous for a 16-bit part – enough for complex metrology firmware, LCD display drivers, and communication protocol stacks without external memory. The 32 KB RAM supports multi-channel data buffering from the six Σ-Δ ADCs. ## Peripherals – six 24-bit Σ-Δ ADCs for precision measurement The standout feature is the six 24-bit sigma-delta analog-to-digital converters, purpose-built for polyphase energy metering. Each channel can digitize voltage and current inputs simultaneously, supporting Class 0.2 accuracy. Additional peripherals include a brown-out detect/reset, DMA, LCD driver, POR, PWM, and watchdog timer. ## Package and environment – 128-LQFP, industrial temperature Housed in a 128-LQFP package (20x14 mm body), surface-mount only.","metaTitle":"Texas Instruments MSP430F67691IPEUR 16-bit MCU, 25 MHz","metaDescription":"Texas Instruments MSP430F67691IPEUR 16-bit MCU with 25 MHz core, 512 KB Flash, 32K x 8 RAM, 6x24-bit Σ-Δ ADC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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, 6x24b 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":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67691","Program Memory Size":"512KB (512K 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":"$16.1439","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d25833ae3f3e8231a64b1693e0a84f1a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for MSP430F67691IPEUR?","answer":"The MSP430F6xx family includes pin-compatible variants with similar peripheral sets; evaluate the MSP430F6779 series or MSP430F67641 for metering applications.
