3 / 11 page Serial Data Input Timing Pin Functions No. 4248-3/11 LC74770M No. Symbol Pin Function 1 VSS Ground pin Ground connection 2 OSCIN LC oscillator pin Connections for the coil and capacitor that form the oscillator that generates the character output 3 OSCOUT dot clock. 4 CKOUT/TEST Clock output/test Provides the OSCOUT output (when RST is low) and the test mode output. output pin 5 P0 General-purpose port 0 General-purpose port (PORT0) output output pin 6 P1 General-purpose port 1 General-purpose port (PORT1) output output pin 7 CS Enable input pin Enable input for the serial data input function. Serial data input is enabled when this pin is low. A pull-up resistor is built in, i.e., this is a hysteresis input. 8 SCLK Clock input pin Clock input for the serial data input function. A pull-up resistor is built in, i.e., this is a hysteresis input. 9 SIN Data input pin Serial data input. A pull-up resistor is built in, i.e., this is a hysteresis input. 10 VSS Ground pin Ground connection 11 NC No connection 12 NC No connection Unused pins. 13 NC No connection These pins must be left open or connected to ground. 14 NC No connection 15 CHA1 Character 1 output pin System 1 character data output 16 BLK1 Blank 1 output pin System 1 blank data output 17 CHA2 Character 2 output pin System 2 character data output 18 BLK2 Blank 2 output pin System 2 blank data output 19 P3 General-purpose port 3 General-purpose port (PORT3) output output pin 20 P2 General-purpose port 2 General-purpose port (PORT2) output output pin 21 VSYNC Vertical synchronizing Input for the vertical synchronizing signal (active low) signal input pin 22 HSYNC Horizontal synchronizing Input for the horizontal synchronizing signal (active low) signal input pin 23 RST Reset input pin System reset input (active low) A pull-up resistor is built in, i.e., this is a hysteresis input. 24 VDD Power supply pin (+5 V) Power supply (+5 V) |
