Product Summary
The WCAYUEP52159 is a fast 8051 compatible microcontroller with a redesigned processor core without wasted clock and memory cycles. Typically, the instruction executing time of WCAYUEP52159 is 1.5 to 3 times faster than that of traditional 8051, depending on the type of instruction. In general, the overall performance is about 2.5 times better than the original for the same crystal speed. Consequently, the WCAYUEP52159 is a fully static CMOS design; it can also be operated at a lower crystal clock.
