The 512 KB Flash and 16K x 8 RAM provide enough headroom for the metrology firmware stack plus communication protocol handling. ## Peripheral set and connectivity for metering and control Beyond the sigma-delta converters, the device integrates a 10-bit ADC (8 channels), DMA for data movement without CPU intervention, an LCD driver for direct display connection, and PWM and watchdog timer for real-time control. ## 128-pin LQFP — board area and routing Housed in a 128-LQFP package (20x14 mm body), this is a surface-mount part with 90 I/O available. The fine-pitch QFP demands careful decoupling placement — plan for a solid ground plane and a 1 µF ceramic per supply pin cluster. ## Active lifecycle — no near-term LTB risk For BOM planning, this is a low-risk line item for multi-year production runs.","metaTitle":"TI MSP430F67681AIPEU 16-bit MCU, 25 MHz, 512 KB Flash","metaDescription":"Texas Instruments MSP430F67681AIPEU 16-bit MCU with MSP430 CPUXV2 core, 25 MHz, 512 KB Flash, 16K x 8 RAM, 6x24b sigma-delta ADC, 90 I/O, -40°C 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":"Tube","RAM Size":"16K 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":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67681","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":"$17.3538","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/94013ff2fb2ad301a731e282d067c425.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F67681AIPEU active or obsolete?","answer":"The MSP430F67681AIPEU is listed as active by Texas Instruments."},{"question":"What is the difference between MSP430F67681AIPEU and MSP430F67681AIPN?","answer":"The suffix difference indicates packaging variant.
