VL82C201 - PC/AT-COMPATIBLE SYSTEM CONTROLLER

General Description

The VL82C201 PC/AT-Compatible System Controller replaces an 82C284 Clock Controller and an 82C288 Bus Controller (both are used in '286-based systems), an 82C84A Clock Generator and Driver, two PAL16L8 devices (used for memory decode), and approximately 30 other less complex integrated circuits used

Key Features

  • Fully compatible with IBM PC/AT-type designs.
  • Replaces 36 integrated circuits on the PC/AT-type board.
  • Supports 20 MHz system clock.
  • Device is available as "cores.
  • for user-specific designs.
  • Sink 24 mA on slot driver outputs.
  • Designed in CMOS for low power consumption PC/AT-.
