SC9028-023是一块用于红外遥控系统中的专用发射集 成电路，采用CMOS工艺制造。它具有32个标准功能键， 通过外接二极管，可将功能键扩充至64个。另外，它还提 供8位的用户编码，可支持多达256种系统。

The Hynix HY5DU561622DT is a 268,435,456-bit CMOS Double Data Rate(DDR) Synchronous DRAM, ideally suited for the point-to-point applications which requires high bandwidth. The Hynix 16Mx16 DDR SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the clock. While all addresses and control inputs are latched on the rising edges of the CK (falling edges of the /CK), Data, Data strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data paths are internally pipelined and 2-bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible with SSTL_2.

The CS6750 MPEG-4 Decoder is a highly integrated application specific silicon core for low bit-rates up to 384kbps video decode. It is fully compliant with ISO/IEC14496-2 Video Simple Profile levels 0 through 3, with integrated error resilience and image post-processing. The CS6750 decoder is ideal for wireless applications that require real-time video decode in a power and area efficient solution. It also provides advantages for high-end solutions such as video conferencing and Internet video streaming.
