DATASHEET 82C37A CMOS High PerformanceProgrammable DMA Controller FN2967 Rev 4.00 October 2, 2015 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.

82C37A Features

* for flexible operation. The 82C37A is designed to be used with an external address latch, such as the 82C82, to demultiplex the most significant 8-bits of address. The 82C37A can be used with industry standard microprocessors such as 80C286, 80286, 80C86, 80C88, 8086, 8088, 8085, Z80, NSC800, 80186
