Product Summary

The p87c550ebaa is a high-performance microcontroller fabricated with Philips high-density CMOS technology. This Philips CMOS technology of the p87c550ebaa combines the high speed and density characteristics of HMOS with the low power attributes of CMOS. Philips epitaxial substrate minimizes latch-up sensitivity. The CMOS 8XC550 has the same instruction set as the 80C51.
