CMOS PROGRAMMABLE DMA CONTROLLER
DESCRIPTION
The M5M82C37AP is a programmable 4-channel DMA (Direct Memory Access) controller. This device is specially designed to simplify data transfer at high trasfer rate for microcomputer systems. Fabricated using the silicon-gate CMOS technology, the M5M82C37AP operates using a single 5V power supply.
FEATURES
5V single supply, single TTL clock Four channel DMA controls with priority DMA request
acknowledge functions DMA enable/disable, automatic initialization enable/dis-
able, address increment/decrement programmability for each cannel Programmable DREQ input and DACK output logic polarity Direct connecting permits easy DMA channel expansion. Memory to memory data transfer EOP input/output permits DMA operation completion check as well as forcibly completing DMA operation.
APPLICATION
DMA control of peripheral equipment such as floppy diskettes and CRT terminals that require hig...
