P89LPC901 - 8-bit microcontrollers

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.

Key Features

  • 2.1 Principal 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. (P89LPC901 Timer 0 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 compara.

P89LPC901/902/903 8-bit microcontrollers with two-clock 80C51 core 1 kB 3 V Flash with 128-byte RAM Rev. 05 — 17 December 2004 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. 2. Features 2.1 Principal 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.
