The Intel P8237A-4 is a high-performance Direct Memory Access (DMA) controller from the P8237 series. This MOS technology device features 4 independent DMA channels, enabling efficient data transfer between memory and peripherals without direct CPU intervention. Operating at a maximum clock frequency of 4MHz, it supports an 8-bit external data bus and a 16-bit address bus, making it compatible with 8080 and 8085 bus architectures. The component is housed in a 40-pin PDIP package (R-PDIP-T40) with through-hole mounting and a terminal pitch of 2.54mm. Its typical operating voltage is 5V, with a maximum of 5.25V and a minimum of 4.75V. The P8237A-4 is suitable for applications requiring high-speed data handling, including early computer systems and embedded control applications. It operates within an ambient temperature range of 0°C to 70°C.
