Quality Control: Learn More
Intel D8237A is a 4-channel NMOS DMA controller from the D8237 series, operating at a maximum clock frequency of 3MHz. This component features single, block, and demand transfer modes, along with fixed and rotational priority interrupt modes. It offers independent priority control for DREQ and DACK signals. The device supports a 16-bit address bus width and an 8-bit external data bus, ensuring compatibility with the 8080 and 8085 processor architectures. Supplied in a 40-pin CDIP package (R-GDIP-T40), the D8237A operates within a temperature range of 0°C to 70°C, with a nominal supply voltage of 5.0V. This controller is integral to systems requiring efficient direct memory access, commonly found in legacy computing systems and embedded applications where data throughput is critical.
