82C37A
CMOS High Performance
Programmable DMA Controller
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.
The 82C37A controller 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.
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 and
others. Multimode programmability allows the user to select
from three basic types of DMA services, and reconfiguration
under program control is possible even with the clock to the
controller stopped. Each channel has a full 64K address and
word count range, and may be programmed to autoinitialize
these registers following DMA termination (end of process).

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
