M35046-XXXSP/FP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35046-XXXSP/FP is a character pattern display control IC can display on the liquid crystal display and the plasma display. It uses a silicon gate CMOS process and it housed in a 20-pin shrink DIP package (M35046-XXXSP) or a 20-pin shrink SOP package (M35046XXXFP). For M35046-001SP/FP that is a standard ROM version of M35046XXXSP/FP respectively, the character pattern is also mentioned.

CS SCK SIN
When CS pin is "L", SIN serial data is taken in when SCK rises. Hysteresis input. Built-in pull-up resistor. This is the pin for serial input of data and addresses for the display control register and the display data memory. Hysteresis input. Built-in pull-up resistor. This is the pin for external clock input. Please connect to +5V with the power pin. This is the output port. Port data is set by PTD6. This is the output port. Port data is set by PTD7. Please connect to GND using circuit earthing pin. This pin can be toggled between port pin output and BLNK0 signal output. This pin can be toggled between port pin output and R signal output. This is the output port. Port data is set by PTD2. This pin can be toggled between port pin output and G signal output. This is the output port. Port data is set by PTD4. This pin can be toggled between port pin output and B signal output. This pin inputs the horizontal synchronous signal. Hysteresis input. This pin inputs the vertical synchronous signal. Hysteresis input. Please connect to +5V with the power pin.
