M5M82C37AP - 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.
