M5L8259AP - PROGRAMMABLE INTERRUPT CONTROLLER

Description

The M5LB259AP is a proqrammable LSI for interrupt control.

It is fabricated using N-channel silicon-gate ED-MaS technology and is designed to be used easily in connection with an BOB5A, BOB6 or BOB8.

Features

  • Single 5V supply voltage.
  • TTL compatible.
  • CALL instruction to the CPU is generated automatically.
  • Priority, interrupt mask and vectored address for each in- terrupt request input are programmable.
  • Up to 64 levels of interrupt requests can be controlled by cascading with M5LB259AP.
  • Polling functions.
