1. General description
The P89LPC9301/931A1 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 P89LPC9301/931A1 in order to reduce component count, board space, and system cost.
