For fast memory data manipulation, the Z86250 offers
segmented base registers. The device also features
PSRAM memory control and refresh logic.
The DBE is optimized to work with Zilog's Z89300 series of
TV controller devices to provide a cost-effective solution
for StarSight programming-guide data extraction and
display.
Zilog's 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.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.:
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
