GENERAL DESCRIPTION	P89LPC906/907/908
1. GENERAL DESCRIPTION

The P89LPC906/907/908 is a single-chip microcontroller designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC906/907/908 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 P89LPC906/907/908 in order to reduce component count, board space, and system cost.
