Description

The MSM82C37B-5RS/GS/VJS, DMA (Direct Memory Access) controller is capable of highspeed data transfer without CPU intervention and is used as a peripheral device in microcomputer systems. The device features four independent programmable DMA channels.

Due to the use of silicon gate CMOS technology, standby current of MSM82C37B-5RS is 10 mA (max.), and power consumption is as low as 10 A (max.) when a 5 MHz clock is generated.

All items of AC characteristics are compatible with intel 8237A-5.
