■ DESCRIPTIONS
The S1C33A01 is a high performance 32-bit controller with various serial interfaces, I2S I/O interface, MMC controller and
infrared remote controller. It is suitable for multimedia interface controllers such as audio and various I/O equipment.
The S1C33A01 provides an I2S interface that has bidirectional I/O channels, this allows recording and external audio input
as well as audio and voice outputs. Also it has a hardware arithmetic accelerator to lighten the load on multimedia
processing such as audio decoding. An audio player system can be implemented using the accelerator with the I2S interface.
The infrared remote controller, input ports and the serial interfaces are used to easily implement various user interfaces. The
S1C33A01 supports reading/writing data from/to large capacity storage media such as various card media and Flash
memory through the built-in MMC controller, SPI interface and SLC/MLC NAND Flash interface.
Furthermore, the local bus interface for an external LSI allows connection of an external LSI such as an LCD controller and
USB controller to expand the functions. The S1C33A01 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 S1C33A01 functions are implemented by EPSON SoC (System on Chip) design technology using 0.18 μm Multi-Vth.
CMOS Process.
