Description
The W77E58B-40 is an 8-bit CMOS microcontroller in the IC Chips product category. It features a redesigned processor core that eliminates wasted clock and memory cycles, resulting in faster execution of every 8051 instruction compared to the original 8051 for the same crystal speed. With an overall performance that is about 2.5 times better than the original, it offers the same throughput with lower clock speed, leading to improved power consumption.
