M5L8257P-5 - PROGRAMMABLE DMA CONTROLLER

Description

The M5L8257P-5 is a programmable, 4-channel direct memory access (DMA) controller.

It is produced using the Nch'annel silicon-gate ED-MaS process and is specifically designed to simplify data transfer at high speeds for microcomputer systems.

The LSI operates on a single 5V power supply.

Features

  • Single 5V supply voltage.
  • Single TTL compatible.
  • Priority DMA request logiC.
  • Channel-masking function.
  • Terminal count and Modulo 128 outputs.
  • 4-channel DMA controller.
  • Compatible with MELPS85 devices.
