µPD6466

On-screen Character Display CMOS LSI for 512-Character, 12-Row, 24-Column, Camera-Contained VCR



- Only a version with NEC standard character ROM code is available for the µPD6466.



Overview

The information in this document is subject to change without notice.
The µPD6466 is a CMOS LSI for on-screen character display, and can be used in combination with a microcomputer to display the tape counter, time, and date in the view finder of a video camera, or the time of a video tape, messages such as dates on pictures, and channel number on a TV screen.
Characters are displayed in 12 (horizontal) by 18 (vertical) dots. Two or more characters can be combined to display Kanji (Japanese characters) and symbols. This LSI supports color view finders and is provided with three sets of character output signals (RGB output: for color view finder, VC1 output: for recording (or monitor pin), VC2 output: for monitor pin (or recording)).
In addition, the µPD6466 is also equipped with a power-ON clear function and a video RAM batch clear command so that it can mitigate the workload of the microcomputer.
The command format of this LSI is identical to that of the existing models, the µPD6461 and 6462, and therefore, the µPD6466 is compatible with the existing models, and the software resources for the existing models can be used.


Features

  • Number of display characters : 12 rows, 24 columns (288 characters)
  • Types of character : 512 types (ROM). Changeable by using mask code option.
  • Character size : Can be expanded up to four-fold in vertical and horizontal directions independently, in units of lines.
  • Number of character colors : 8 colors
  • Framing : Framing or no framing, or white or black framing selectable in screen units.
  • Dot matrix : 12 (horizontal) × 18 (vertical) dot configuration. No gap between adjacent characters.
  • Blinking : Blinking can be turned ON/OFF in character units. The blinking ratio is 1:1.
    The blinking frequency can be selected from about 1 Hz, about 2 Hz, and about 0.5 Hz in screen unit.
  • Character color reversing function : The color of the character and that of the background can be reversed.
  • Character left and right reverse : Left and right can be reversed for display in character units.
  • Background : No background, blank background, or filled background selectable in screen units.
  • Blue back function : Blue or white can be selected as the background.
  • Signal output : 3 sets (output (1) R, G, B+BLK/VC1+VBLK1/VC2+VBLK2 and
    output (2) R+RBLK/B+BBLK/G+GBLK selectable by command)
    When output (1) is selected, VC1 and VC2 outputs can be selected from three types.
  • Video RAM data clear : Implemented by video RAM batch clear command or by clear function on power-ON.
  • Interface with microcomputer : 8-bit variable word length serial input (LSB first/MSB first selectable by command)
  • Supply voltage : Supports low voltage (2.7 to 5.5 V)
  • Process : CMOS low power consumption
