...................................87 - 2 - W77E058A 1. GENERAL DESCRIPTION The W77E058 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

wait cycles need to be inserted. Figure 19 and Figure 20 are the timing diagrams for the Intel 8031, 8051 and 8085 (5 MHz) microcontrollers. By NANDing the address latch enable (ALE) output with the high-byte address (P2) decode output, CS is generated. Figure 14 summarizes the connection of these Intel

are performed in one single cycle. The MCU uses 1 clock per cycle. BK-51 can executes the normal 8051 instruction set, so you can use the standard 8051 tools to develop your application. All the instructions are equal to 8051‘s binary codes and function, includes operate code, addressing mode, affect on PSW. But the timing of instruction is different with 8051. In many 8051 products, the machine period is different with clock period, one machine period last on 2~12 clock period, but BK-51 only has clock period, all the instructions are based on the clock
