Intel P8237A is a 4-channel NMOS DMA controller operating up to 3MHz. This component supports single, block, and demand transfer modes, alongside fixed and rotational priority interrupt modes. It features independent priority control for DREQ and DACK signals. The P8237A is designed with a 16-bit address bus width and an 8-bit external data bus, offering compatibility with 8080 and 8085 microprocessors. Packaged in a 40-pin Ceramic Dual In-line Package (CDIP40), it operates within a temperature range of 0°C to 70°C and requires a supply voltage of 5V. This component finds application in industrial automation and legacy computing systems.
