AT89LP216
Preliminary
1. Description
The AT89LP216 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 nonvolatile memory technology and is compatible with the
industry-standard MCS-51 instruction set. The AT89LP216 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 cycles, forcing instruc-
tions to execute in 12, 24 or 48 clock cycles. In the AT89LP216 CPU, instructions
need only 1 to 4 clock cycles providing 6 to 12 times more throughput than the stan-
dard 8051. Seventy percent of instructions need only as many clock cycles as they
