GENERAL DESCRIPTION

Zilogs Z86250 StarSight Data Base Engine (DBE) is designed to process extracted data for the StarSight on-screen programming guide. The device is logically equivalent to the DBE1200 for StarSight applications.

The Z86250 provides a number of important peripheral functions, such as the IR Blaster to send command signals to the VCR, and low-power management to avoid loss of data.
