The Atmel
controller with 24/32 KB of In-System Programmable Flash program memory. The devices are
manufactured using Atmel's high-density nonvolatile memory technology and are compatible
with the industry-standard 80C51 instruction set.
The AT89LP51RB2/RC2/IC2 is built around an enhanced CPU core that can fetch a single byte
from memory every clock cycle. In the classic 8051 architecture, each fetch requires 6 clock

AT89LP51RB2/RC2/IC2 CPU, standard instructions need only one to four clock cycles providing
six to twelve times more throughput than the standard 8051. Seventy percent of instructions
need only as many clock cycles as they have bytes to execute, and most of the remaining
instructions require only one additional clock. The enhanced CPU core is capable of 20 MIPS
throughput whereas the classic 8051 CPU can deliver only 4 MIPS at the same current con-
sumption. Conversely, at the same throughput as the classic 8051, the new CPU core runs at a
much lower speed and thereby greatly reducing power consumption and EMI. The
