GENERAL DESCRIPTION
2003 Dec 8 7
1. GENERAL DESCRIPTION
The P89LPC901/902/903 is a single-chip microcontroller designed for applications demanding high-integration, low cost
solutions over a wide range of performance requirements. The P89LPC901/902/903 is based on a high performance processor
architecture that executes instructions six times the rate of standard 80C51 devices. Many system level functions have been
incorporated into the P89LPC901/902/903 in order to reduce component count, board space, and system cost.
