■ DESCRIPTIONS
The S1C33L27 is a 32-bit application specific RISC controller. It is suitable for applications that require an abundance of
input/output ports and serial interfaces, USB, ADC, and a display panel, such as electronic dictionaries and control panels on
OA/FA equipment.
The S1C33L27 incorporates an LCD controller and VRAM supporting QVGA display in single-chip. Adding an external
SDRAM expands this capability into more higher resolution and displayable colors (e.g., VGA display, 16M-color display).
It provides an interface to communicate with a built-in RAM type LCD driver.
