General Description

The P89LPC9321 is a single-chip microcontroller, available in low cost 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 P89LPC9321 in order to reduce component count, board space, and system cost.

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 and a 512-byte auxiliary on-chip RAM.
  • 512-byte customer data EEPROM on-chip allows serialization of devices, storage of setup parameters, etc.
  • Two analog comparators with selectable inpu.
