CMOS High Performance

Features

• Compatible with the NMOS 8237A

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.

• Four Independent Maskable Channels with

Autoinitialization Capability

• Cascadable to any Number of Channels

• High Speed Data Transfers:

- Up to 4MBytes/sec with 8MHz Clock

- Up to 6.25MBytes/sec with 12.5MHz Clock

• Memory-to-Memory Transfers

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.

• Static CMOS Design Permits Low Power Operation

- ICCSB = 10µA Maximum

- ICCOP = 2mA/MHz Maximum

• Fully TTL/CMOS Compatible

• Internal Registers may be Read from Software

• Pb-Free Plus Anneal Available (RoHS Compliant)

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
