Rev. 04 ― 21 November 2003 Product data

1. General description
The P89LPC901/902/903 are single-chip microcontrollers in low-cost 8-pin 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 P89LPC901/902/903 in order to reduce component count, board space, and system cost.
