General Description

The P89LPC924/925 are single-chip microcontrollers designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements.

The P89LPC924/925 is 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 P89LPC924/925 in order to reduce component count, board space, and system cost.

Key Features
