UPD6461 - CMOS LSI CHIP
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.
Input pin for control data.
Data is read in synchronization with the clock input to the CLK pin.
Pin used for the power-on clear function.

DATA SHEET µPD6461, 6462 CMOS LSI CHIP FOR CAMCORDER ON-SCREEN CHARACTER DISPLAY (12 ROWS × 24 COLUMNS) MOS INTEGRATED CIRCUIT 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 (heig
UPD6461 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
* Number of character colors
* Ba
