Product Details:
The µPD6464A,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 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 (µPD6464A)/256 (µPD6465) (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 screenunits.
• 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 (µPD6464A 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
