AT89LP213/214 is a low-power, high-performance, CMOS 8-bit microcontroller with 2K bytes of in-system programmable Flash memory. The device is manufactured using Atmel's high-density non-volatile memory technology and is compatible with the industry standard MCS-51 instruction set. AT89LP213/214 is built on an enhanced one-byte-per-clock CPU core. In the classical 8051 architecture, each byte fetch takes 6 clock cycles, which results in 12, 24 or 48 clock cycles to execute an instruction. In the AT89LP213/214 CPU, instruction execution takes only 1 to 4 clock cycles, resulting in a throughput that is 6 to 12 times faster than standard 8051. Seventy percent of the instructions only require the same number of clock cycles as their byte size.
