PC/AT-COMPATIBLE SYSTEM CONTROLLER
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 as wait state logic. The device accepts a user supplied PROCCLK or generates its own using an internal clock modulation circuit.
