The Intel D82031 is a CMOS DRAM controller designed for systems utilizing 8086, 8088, 80186, and 80188 bus architectures. This component, part of the D8203 series, features a 4-bank memory organization and a 14-bit address bus, enabling direct access to a substantial memory space. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal 5.0V requirement, and exhibits a maximum supply current of 290mA. The D82031 is housed in a 40-pin PDIP package (JESD-30 Code: R-PDIP-T40) with through-hole terminals spaced at 2.54mm, making it suitable for traditional PCB mounting. Its operating temperature range is from 0°C to 70°C. This device finds application in personal computers and embedded systems requiring efficient DRAM management.
