The P89LPC9331/9341/9351 are single-chip microcontrollers designed for applications
demanding high-integration, low cost solutions over a wide range of performance
requirements. The P89LPC9331/9341/9351 are 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
P89LPC9331/9341/9351 in order to reduce component count, board space, and system
cost.
