D6461 - CMOS LSI

Datasheet Summary

Description

Input pin for the data read clock.

The data input to the DATA pin is read at rising edges of the clock.

Serial transfer is accepted when this pin is low.

Features

  • Maximum number of characters: 12 rows × 24 columns (288 characters).
  • Number of character patterns : 256 (µPD6461)/128 (µPD6462) (stored in ROM). Each pattern can be changed by specifying a mask code option.
  • Character size : One dot per line or one dot per two lines (field).
  • Number of character colors : 8.
  • Background : No background, minimum background, or overall background can be selected for the entire screen, together with rimming ON/OFF.

DATA SHEET MOS INTEGRATED CIRCUIT µPD6461, 6462 CMOS LSI CHIP FOR CAMCORDER ON-SCREEN CHARACTER DISPLAY (12 ROWS × 24 COLUMNS) The µPD6461, 6462 are CMOS LSI chips designed to provide on-screen character display for camcorders. When combined with a microcontroller, the µPD6461, 6462 control the display of the characters displayed in the viewfinder (count, time, date, etc.) and the recording of characters onto video tape (time, date, etc.). Each character is created using 12 (width) × 18 (height) dots. Kanji characters and graphic symbols can also be displayed by using two or more characters.
