An additional 8-channel 10-bit SAR ADC handles auxiliary measurements. Three independent 24-bit sigma-delta converters (listed as peripherals) let this single chip replace a separate analog front-end IC in polyphase energy metering, weigh-scale, or flow-meter designs. Each converter can be assigned to a different sensor channel, reducing component count and board area. The 8x10b SAR ADC adds headroom for temperature or voltage monitoring without an external mux. For a design targeting a three-phase power monitor, this MCU eliminates the need for a stand-alone metering AFE, saving roughly $2–$4 in BOM cost per channel. For a BOM line, this removes the supply-risk flag that comes with NRND or obsolete parts. The base product number MSP430F67641 supports multiple package and temperature variants, so a design can migrate within the family without a PCB layout change if future requirements shift. ## Boot, debug, and first-power checklist The MSP430 CPUXV2 boots from internal Flash with the BOOT0 pin strapped low. The JTAG/SBW debug interface stays alive even with the watchdog enabled, so firmware recovery is straightforward. The internal oscillator is available at power-up, but for the sigma-delta converters to meet their rated accuracy, an external precision clock or crystal should be considered. The 100-LQFP package (14x14 mm) has an exposed thermal pad — ensure the PCB has a via stitch to a ground plane to keep junction temperature under control when the ADC and CPU run continuously.","metaTitle":"TI MSP430F67641AIPZ 16-bit MCU, 25 MHz, 128KB Flash","metaDescription":"Texas Instruments MSP430F67641AIPZ 16-bit MCU at 25 MHz with 128KB Flash, 8KB RAM, three 24-bit sigma-delta ADCs, 72 I/O, 1.8V–3.6V supply, -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":{"Speed":"25MHz","title":"MSP430F67641AIPZ","Series":"MSP430F6xx","Package":"Tube","RAM Size":"8K x 8","Core Size":"16-Bit","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 3x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"72","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67641","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.7857","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/639692088022cfa279f1eeedee1644b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MSP430F67641AIPZ available via RFQ confirmation?","answer":"The MSP430F67641AIPZ is available to order through independent distribution.
