LPC921F
description
The P89LPC920/921/922 are single-chip microcontrollers designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC920/921/922 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 P89LPC920/921/922 in order to reduce ponent count, board space, and system cost.
