8051 MICROCONTROLLERS
8051 Single Cycle Core Microcontrollers
AT89LP Family Provides High Performance & Low Power
Atmel^® AT89LP family consists of high performance 8-bit microcontrollers that execute most instructions in
a single clock cycle, whereas the classic 8051 CPU requires 12 clock cycles.
At the same MIPS throughput as the classic 8051, existing applications can use a much lower clock
frequency, thus allowing designers to either reduce power consumption by up to 80%. Designers can
also boost the application performance and reach up to 20 MIPS throughput, i.e. 12 times faster than the
traditional 8051 core.
