1. General description
The P89LPC9201/9211/922A1/9241/9251 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the device in order to reduce component count, board space, and system cost.
