P89LPC980 Overview
The P89LPC980/982/983/985 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 P89LPC980/982/983/985 in order to reduce ponent count, board space, and system cost.
P89LPC980 Key Features
