General Description

The P89LPC9381 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 P89LPC9381 in order to reduce component count, board space, and system cost.

Key Features

  • 2.1 Principal features I 4 kB byte-erasable flash code memory organized into 1 kB sectors and 64 B pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. I 256 B RAM data memory on-chip RAM. I 8-input multiplexed 10-bit ADC. Two analog comparators with selectable inputs and reference source. I Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to become a PWM output) and a 23-bit system timer that can also be used as a RT.
