CS82C37A Datasheet PDF - Intersil

The 82C37A is an enhanced version of the industry standard 8237A Direct Memory Access (DMA) controller, fabricated using Intersil’s advanced 2 micron CMOS process. Pin compatible with NMOS designs, the 82C37A offers increased functionality, improved performance, and dramatically reduced power consumption. The fully static design permits gated clock operation for even further reduction of power.
