WT51F104S
【 General Description 】 |
The Weltrend WT51F104S is a general-purpose single chip microcontroller. In addition to using the advanced 3T 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. The above features make the WT51F104S 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 WT51F104S is a low cost high performance product with various kinds of package options to replace the mainstream products on the market. For further competiveness, Weltrend also provides the product in dice and wafer format. |
