µPD16661A
6. LSI PLACEMENT AND ADDRESS MANAGEMENT
Addresses can be managed to allow the use of a maximum of eight µPD16661A devices for configuring a liquid-
crystal display of up to VGA size (480 × 640 dots).
Up to eight of these LSIs can be connected to the same data bus and to the /CS, /WE, and /OE pins, which are
shared.
One screen of the liquid-crystal display can be treated as one memory area in the system, so it is not necessary
to decode more than one µPD16661A device.
The PL0, PL1, and PL2 pins are used to specify the LSI No. and determine the LSI placement. The DIR pin is
used to determine the direction (perpendicular, lateral) of the liquid-crystal display.
