Intel 8257 An 8257 clone by NEC (μPD8257C-5) The Intel 8257 is a direct memory access (DMA) controller, a part of the MCS 85 microprocessor family. The chip is supplied in 40-pin DIP package.
The Intel 8257 and 8237 are programmable DMA controllers widely used in microprocessor systems for high-speed data transfers. This problem of slow data transfer between the input-output port and memory or between two memories is reduced by implementing the Direct Memory Access (DMA) technique.
