Intel P8257-5 is a 4-channel Direct Memory Access (DMA) controller fabricated using CMOS technology. Operating at a maximum clock frequency of 3.125 MHz, this component features an 8-bit address bus width and an 8-bit external data bus width, offering MCS-85 bus compatibility. The P8257 series device is housed in a 40-pin PDIP package with through-hole mounting. Its operational temperature range is from 0°C to 70°C, with a nominal supply voltage of 5.0V, supporting a range of 4.5V to 5.5V. This DMA controller is integral to systems requiring efficient data transfer between peripherals and memory, finding application in computing, industrial automation, and embedded control systems.
