AT89LP4052-16PI

Product Summary

The AT89LP4052-16PI is a low-power, high-performance CMOS 8-bit microcontroller with 2/4K bytes of In-System Programmable Flash memory. The device is manufactured using Atmel high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set. The AT89LP4052-16PI 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, forcing instructions to execute in 12, 24 or 48 clock cycles. In the AAT89LP4052-16PI CPU, instructions need only 1 to 4 clock cycles providing 6 to 12 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.
