DESCRIPTIONS
The S1C33L15 is a high performance 32-bit controller with 16M/64K TFT/64K CSTN LCD controller and hardware arithmetic
accelerator for multimedia applications. It is suitable for use in applications with an LCD panel and audio functions, such as
electronic dictionaries, audio players, image viewers, and mobile equipment.
The S1C33L15 supports various small to middle-size LCD panels, not only 256-color QVGA display by using the 100KB
internal memory but also full-color VGA display by using a large external memory. Also it has a hardware PIP function that
overlays one image on another to lighten the load on the drawing process in the application. This makes it possible to simply
2
create the LCD panel display routine. The hardware arithmetic accelerator and the I C interface for input/output can be used
for decode processing of various audio formats. The on-chip interface modules, MMC controller, NAND Flash controller and
SPI, can be used for image display or audio player applications using media cards. Furthermore, the abundant interfaces
and remote controller are used to realize electronic equipment that supports various user interfaces.
The S1C33L15 not only operates as an LCD control processor on a standalone basis but also it can be used as an LCD
controller by connecting it to an external host processor via the host processor interface (HIF).
The S1C33L15 is equipped with the 32-bit RISC CPU core C33, 2KB instruction/data caches, 100KB RAM,
DMA controller, memory controller (SRAM/SDRAM), various timers, real-time clock and general-purpose I/O
ports as its basic functions, so it can also be used as a high performance general-purpose CPU.
These S1C33L15 functions are implemented by EPSON SoC (System on Chip) design technology using 0.18
μm
Multi-Vth. CMOS Process.
