WT51F116/108
1T 8052 Micro-controller with ADC Function
1. General Description
The WT51F116/108 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 16Kx8 (8Kx8 for WT51F108) Flash
Program Memory, 512x8 RAM, abundant peripheral resources and versatile power management (refer to the
content for more details).
The above features make the WT51F116/108 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 WT51F116/108 is a low cost high performance product with kinds of package to replace the mainstream
products on the market (refer to “WT51F116/108 Application Notes” for more details). In order to contribute more
competitive ability, Weltrend also provides wafer and dice sale for the customer.
