MS6464
OSD CIRCUIT
MS6464 is 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.
FEATURE
* Video signal input/output: Composite video signal
* Number of display characters: 12 lines, 24 columns (288 characters)
* Number of character types: 128
* 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
charactes .
* 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
* 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.
APPLICATIONS
* on-screen character display systems

Function
Inputs clock for data read. Data input to the DATA pin is read at the rising edge of the
clock input to this pin.
Serial transfer can be acknowledged by making this
pin low
nputs control data. Data is read in synchronization with the clock input to the CLK pin.
