Manufacturer: NXP Semiconductors

Overview: www.DataSheet4U.com P89LPC9402 8-bit microcontroller with accelerated two-clock 80C51 core 8 kB 3 V byte-erasable flash with 32 segment 4 LCD driver Rev. 00.01 — 8 April 2009 Preliminary data sheet 1.

General Description

The P89LPC9402 is a multi-chip module consisting of a P89LPC931A1 single-chip microcontroller combined with a PCF8576D universal LCD driver in a low-cost 64-pin package.

The LCD driver provides 32 segments and supports from 1 to 4 backplanes.

Display overhead is minimized by an on-chip display RAM with auto-increment addressing.

Key Features

  • 2.1 Principal features.
  • 8 kB byte-erasable flash code memory organized into 1 kB sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
  • 256-byte RAM data memory.
  • 32 segment × 4 backplane LCD controller supports from 1 to 4 backplanes.
  • Two analog comparators with selectable inputs and reference source.
  • Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or.
