General Description

The P89LPC980/982/983/985 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 P89LPC980/982/983/985 in order to reduce component count, board space, and system cost.

Key Features

  • 2.1 Principal features.
  • 4 kB/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. Both the P89LPC982 and the P89LPC985 also include a 256-byte auxiliary on-chip RAM.
  • 8-input multiplexed 10-bit ADC (P89LPC985, 4-input multiplexed 10-bit ADC on P89LPC983) with window comparator that can generate an interrupt for in or out of range res.
