P87LPC764BD

Product Summary

The P87LPC764BD 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 P87LPC764BD offers 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 P87LPC764BD is based on an accelerated 80C51 processor architecture that executes instructions at twice the rate of standard 80C51 devices.
