描述 Description

The WT56F248/232 is a general-purpose single chip Microcontroller with LCD function 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 (2.2V ~ 5.5V), and high noise immunity, the product consists of 48Kx8 (32Kx8 for WT56F232) Flash Program Memory, 1024x8 RAM (768x8 for WT56F232), abundant peripheral resources and versatile power management (refer to the content for more details). The above features make the WT56F248/232 suitable for a wide range of applications, especially in areas such as home appliances with LCD (rice cooker, microwave oven, and toaster), Thermo-Hygrometer, bidirectional car alarm, remote controller of air conditioner, and so on. The WT56F248/232 is a low cost high performance product with kinds of package to replace the mainstream products on the market (refer to “Pin Configuration” section for more details). In order to contribute more competitive ability, Weltrend also provides dice and wafer sale for the customer.
