DATA SHEET
The
μ
PD6464A,6465 are CMOS LSIs for on-screen character display that control various display systems (such
as tape counters) including the program screens of deck-type VCRs and LD players. These LSIs are used in
combination with a microcomputer.
It can display characters each consisting of 12 (horizontal) by 18 (vertical) dots. Some chinese characters and
some pictograms can also be displayed by combining two or more characters.
The
μ
PD6464A,6465 include a power-ON clear function and a video RAM batch clear command that mitigate the
workload of the host microcomputer. It also has a synchronization separator and a
×
4 multiplier on chip, eliminating
the need of connecting an external separator IC and a crystal resonator, which reduces the mounting area and the
total cost.

: Blinking can be turned ON/OFF in character units. Blinking ratio is 1:1.
Blinking frequency is selectable from about 0.5 Hz, 1 Hz, and 2 Hz in screen
units.
: Can support VCRs with S pins if external mixer is connected because
character signal and blanking signal output pins are provided.
: Video RAM data are cleared by video RAM clear command and power-ON
clear function.
: NTSC/PAL/PAL-M/SECAM/PAL-N (
