This is a purpose-built front end for three-phase energy metering, power-quality monitoring, or multi-channel sensor acquisition. Each converter can be paired with a current transformer or shunt and a voltage divider to simultaneously sample all phases and the neutral. The integrated LCD driver (up to 160 segments) means the same chip can drive a local display without an external controller. The 90 general-purpose I/O pins in the 128-LQFP package give ample room for external memory, serial interfaces, and control signals. Texas Instruments lists the MSP430F67781IPEUR as obsolete. That means no factory orders, no last-time-buy windows, and no guaranteed future availability from the manufacturer. However, the part remains available through independent distribution and surplus inventory channels.","metaTitle":"Texas Instruments MSP430F67781IPEUR, 16-bit 25MHz MCU","metaDescription":"Texas Instruments MSP430F67781IPEUR 16-bit MCU, 25MHz, 512KB Flash, 16KB RAM, 7×24-bit sigma-delta ADC, 90 I/O, 128-LQFP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"25MHz","title":"MSP430F67781IPEUR","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"16K x 8","Core Size":"16-Bit","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","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67781","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":"$17.7578","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9932f995d18fb1d78729c9f12bca0b00.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MSP430F67781IPEUR?","answer":"We source the MSP430F67781IPEUR through independent distribution against an RFQ.
