General Description

The P89LPC912/913/914 are single-chip microcontrollers in low-cost 14-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 P89LPC912/913/914 in order to reduce component count, board space, and system cost.

Overview

P89LPC912/913/914 8-bit microcontrollers with two-clock 80C51 core 1 kB 3 V Flash with 128-byte RAM Rev.

03 — 17 December 2004 Product data 1.

Key Features

  • s 1 kB byte-erasable Flash code memory organized into 256-byte sectors and 16-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. s 128-byte RAM data memory. s Two 16-bit counter/timers. Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output. s 23-bit system timer that can also be used as a Real-Time clock. s Two analog comparators with selectable inputs and reference source. s Enhanced UART with fractional baudrat.
