　　The W77LE58 is a fast 8051 compatible microcontroller with a redesigned processor core without
　　wasted clock and memory cycles. As a result, it executes every 8051 instruction faster than the
　　original 8051 for the same crystal speed. Typically, the instruction executing time of W77LE58 is 1.5
　　to 3 times faster then 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. Giving the
　　same throughput with lower clock speed, power consumption has been improved. Consequently, the
　　W77LE58 is a fully static CMOS design; it can also be operated at a lower crystal clock. The
　　W77LE58 contains 32 KB flash Multiple-Time Programmable(MTP) ROM, and provides operating
　　voltage from 2.7V to 5.5V. All W77LE58 types also support on-chip 1 KB SRAM without external
　　memory component and glue logic, saving more I/O pins for users’ application usage if they use onchip
　　SRAM instead of external SRAM.
