Quality Control: Learn More
Intel P8257 is a 4-channel Direct Memory Access (DMA) controller built with CMOS technology. Operating at a maximum clock frequency of 3.125MHz, this component features an 8-bit address bus and an 8-bit external data bus, ensuring compatibility with the MCS-85 bus architecture. The P8257 series is designed for efficient data transfer operations, commonly found in industrial automation and data acquisition systems. It is housed in a 40-pin PDIP package (R-PDIP-T40) with a 2.54mm terminal pitch, requiring through-hole mounting. The device operates within a supply voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C.
