This is the datasheet of FUJITSU MB90098A on-screen display controller
The MB90098A is a CMOS on-screen display controller from Fujitsu Semiconductor designed for LCD monitors. It operates at a maximum dot clock frequency of 140 MHz and provides demultiplexed 2-pixel parallel output. The main screen supports up to 32 characters by 16 rows and L, M, and S character sizes, with 512 built-in character types. Display functions include normal and graphic characters, borders, character and row backgrounds, enlarged characters, blinking, sprite characters, and screen background characters, with 16 colors for color settings.
The device has a 16-bit serial microcontroller interface using CS, SIN, and SCLK, and comes in a 28-pin plastic SOP package (FPT-28P-M17). The datasheet covers pin assignments and descriptions, input/output circuit types, a block diagram, absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, serial input timing, sync signal timing, ordering information, and package dimensions.
