... The SCE574x is designed for work with the serial port of most common microprocessors. Data is transferred into the display through the Serial Data Input (DATA), clocked by the Serial Data Clock (SDCLK), and enabled by the Load Input (LOAD). The SCE574x Clock I/O (Clk I/O) and Clock Select (CLK- SEL) pins offer the user the capability to supply a high speed external multiplex clock ...

... IC accepts decoded serial data, which is stored in the internal RAM. Asynchronously the RAM is read by the character multi- plexer at a strobe rate that results in a flicker free display. Figure „Block Diagram“ (page 7) shows the three functional areas of the IC. These include: the input serial data register and control logic, a 140 bits two port RAM, and an internal multiplexer/display driver ...
