The Atmel® AT89LP family takes 8051 microcontroller power to a new level. These high performance 8-bit microcontrollers execute most instructions in a single clock cycle, compared to 12 clock cycles in the classic 8051 CPU. At the same MIPS throughput as the classic 8051, existing applications can use a much lower clock frequency, enabling power consumption reduction by up to 80 percent. Application performance can be boosted up to 20 MIPS throughput 12 times faster than the traditional 8051 core.
