... Low Power Flash Microcontrollers Summary The Atmel AT89LP family of products features a single-cycle 8051 core within a highly integrated microcontroller allowing designers to achieve 6x to 12x more performance compared to classic 8051 devices. The 8051 architecture has been used in the industry for decades and remains very popular with system developers. AT89LP microcontrollers offer full binary code compatibility with the original MSC® ...

... On-Chip Debug system allows development of firmware within the target system Improved Performance The Atmel AT89LP family is based on a low-power, high-performance 8-bit single-cycle 8051 core. The classic 8051 CPU requires 12 clock cycles for every instruction byte fetch, whereas the new AT89LP CPU employs a simple two-stage pipeline that requires only one clock cycle for every byte fetch ...

... Full CMOS mode allows for higher current sourcing that standard 8051s. Low Power The Atmel AT89LP Family was designed not only with performance in mind, but also power consumption. How can an architecture designed for high performance also be low power? Typical dynamic power is often written with the following equation where C is the capacitance toggled, Vcc is the supply voltage and f is the operating frequency: Power consumption can be reduced by decreasing any of these three parameters ...

... MIPS Ease of Migration Atmel AT89LP microcontrollers are built around an enhanced 8051 CPU that delivers more performance and yet remains 100% fully binary compatible with the industry standard MCS®51 instruction set. Keeping the same instruction set allows legacy code already written for the 8051 architecture to run on an AT89LP ...
