General Description

The P87LPC778 is a 20-pin single-chip microcontroller designed for low pin count applications demanding high-integration, low cost solutions over a wide range of performance requirements.

A member of the Philips low pin count family, the P87LPC778 offers a 4 channel, 8-bit A/D converter, programmable oscillator configurations for high and low speed crystals or RC operation, wide operating voltage range, programmable port output configurations, selectable Schmitt trigger inputs, LED drive outputs, and a built-in Watchdog timer.

The P87LPC778 is based on an accelerated 80C51 processor architecture that executes instructions at twice the rate of standard 80C51 devices.
