HS1-82C37ARH-Q Datasheet | Harris Corporation

Description The Harris HS-82C37ARH is an enhanced, radiation hardened CMOS version of the industry standard 8237A Direct Memory Access (DMA) controller, fabricated using the Harris hardened field, self-aligned silicon gate CMOS process. The HS-82C37ARH offers increased functionality, improved performance, and dramatically reduced power consumption for the radiation environment. The high speed, radiation hardness, and industry standard configuration of the HS-82C37ARH make it patible with radiation hardened microprocessors such as the HS-80C85RH and the HS-80C86RH. The HS-82C37ARH can improve system performance by allowing external devices to transfer data directly to or from system memory. Memory-to-memory transfer capability is also provided, along with a memory block initialization feature . DMA requests may be generated by either hardware or software, and each channel is independently programmable with a variety of features for flexible operation. Static CMOS circuit design insures low...
