WT51F108S/104S
1T 8052 Micro-controller with ADC Function
1. General Description
The WT51F108S/104S is a general-purpose single chip Microcontroller provided by Weltrend, a well-known IC
Design House in Taiwan. 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 8Kx8 (4Kx8 for WT51F104S) Flash
Program Memory, 512x8 RAM, abundant peripheral resources and versatile power management (refer to the
content for more details).
The above features make the WT51F108S/104S 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 WT51F108S/104S is a low cost high performance product with kinds of package to replace the
mainstream products on the market (refer to “WT51F108S/104S Application Notes” for more details). In order to
contribute more competitive ability, Weltrend also provides wafer and dice sale for the customer.
