Advanced Micro Devices D8237A-4B is a 4-channel Direct Memory Access (DMA) controller, operating at up to 4MHz. This NMOS device, housed in a 40-pin Ceramic Dual In-line Package (CDIP40), supports 8-bit address and data buses, with compatibility for 8080A and 9080A processors. It features four independent DMA channels, facilitating high-speed data transfers between memory and peripherals without continuous CPU intervention. The operating temperature range is 0°C to 70°C, with a nominal supply voltage of 5.00V (4.75V to 5.25V). This component is commonly utilized in embedded systems, industrial automation, and data acquisition applications where efficient data throughput is critical. The D8237 series DMA controller is designed for robust performance in demanding environments.
