ON-SCREEN CHARACTER DISPLAY CMOS LSI FOR 12-LINE,24-COLUMN DECK-TYPE VCR，Chinese, Japanese, English and other multi-language text display text editor
μPD6465CS-509 and UDP6465C1-509 are exactly the same thing, just different name, label writing and physical printing are different, in fact they are the same Part number
The UPD6464A,UPD6465 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 μPD6464A,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.
FEATURES
■ Video signal input/output : Composite video signal
■ Number of display characters : 12 lines, 24 columns (288 characters)
■ Number of character types : 128 (UPD6464A)/256 (UPD6465) (ROM). Variable by mask code option.
■ Character size : 1 dot/1 line. 2 lines (field) can be displayed in line units.
■ Character color : White (single color)
■ Background : No background, black framing, black-on-white, and black filling
■ Dot matrix : 12 (horizontal) ′ 18 (vertical) dots without gap between adjacent characters
■ Blinking : 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.
■ Character signal output: : Can support VCRs with S pins if external mixer is connected because character signal and blanking signal output pins are provided.
■ Video RAM data clear : Video RAM data are cleared by video RAM clear command and power-ON clear function.
■ Supported video signal method : NTSC/PAL/PAL-M/SECAM/PAL-N (UPD6464A only)
■ Internal circuit : Synchronization separation circuit for composite synchronizing signal and ′4 multiplier
■ Interface with microcomputer : Serial input type of 8-bit variable word length
■ Supply voltage : +5 V, single power supply

用于12行，24列甲板式VCR的屏幕字符显示cmos LSI(大规模集成电路)，中日英等多国语言文字显示编辑
μPD6465CS-509和UDP6465C1-509是完全一样的东西，叫法不同而已，标签的写法和实物印刷有差异，实际上它们是同一个型号。
UPD6464A、UPD6465是用于屏幕字符显示的CMOS LSI，控制各种显示系统(如磁带计数器)，包括甲板式录像机和LD(LASER DISC)播放机的程序屏幕。这些LSI与微型计算机结合使用。
它可以显示由12个(水平)× 18个(垂直)点组成的字符。一些汉字和一些象形文字也可以由两个或两个以上的字符组合显示。
μPD6464A、UPD6465具有上电清除功能和视频RAM批处理清除命令，减轻了主机的工作负荷。它还在芯片上有一个同步分隔器和' 4倍频器，消除了连接外部分隔IC和晶体谐振器的需要，这减少了安装面积和总成本。
