Description
The AT89LP2052/LP4052 is a low-power, high-performance CMOS 8-bit microcon-
troller with 2/4K bytes of In-System Programmable Flash memory. The device is
manufactured using Atmel's high-density nonvolatile memory technology and is com-
patible with the industry-standard MCS-51 instruction set. The AT89LP2052/LP4052
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 required 6 clock cycles, forc-
ing instructions to execute in 12, 24 or 48 clock cycles. In the AT89LP2052/LP4052
CPU, instructions need only 1 to 4 clock cycles providing 6 to 12 times more through-
put 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 consump-
tion. Conversely, at the same throughput as the classic 8051, the new CPU core runs
at a much lower speed and thereby greatly reduces power consumption.
