General Description

The VL82C201 PC/AT-patible 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 plex integrated circuits used as wait state logic.

The device accepts a user supplied PROCCLK or generates its own using an internal clock modulation circuit.

It also accepts a 14.318 MHz crystal to control the video clock and supplies reset and clock signals to the I/O slots.

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-.
