10M ehternet can be used on all our MCU. 100M can be supported on our ARM9
MCU |

sharp的mcu是否已经在一些PDA中得到应用，能否简单介绍。目前市场占有率是多少 |
| [答：RaedSabha] |
Sharp"s BlueStreak MCU line is less than 3 years old. We
have won several PDA applications in China and South East
Asia. As for market share, it is very small at this
point. However, we are focusing our efforts on China market and
expect to get a good share of the market by 2006. |
