WT51F104

【 General Description 】

The WT51F104 is a general-purpose single chip Microcontroller provided by Weltrend, a well-known IC Design House in Taiwan. In addition to using the advanced IT 8052 single-chip core, wide and low operating voltage range (1.8V ~ 5.5V), and high noise immunity, the product consists of 4Kx8 Flash Program Memory, 256x8 RAM, abundant peripheral resources and versatile power management (refer to the content for more details).The above features make the WT51F104 suitable for a wide range of applications, especially in areas such as home appliances, cooling fan, electronic ballast, car alarm, ultrasonic parking assistant sensors, and so on. The WT51F104 is a low cost high performance product with kinds of package to replace the mainstream products on the market (refer to “WT51F104 Application Notes” for more details). In order to contribute more competitive ability, Weltrend also provides wafer and dice sale for the customer.
