DESCRIPTION\nThe Philips 8XC550 is a high-performance microcontroller fabricated with Philips high-density CMOS technology. This Philips CMOS technology 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.\nThe 8XC550 contains a 4k × 8 EPROM (87C550)/ROM (83C550)/ROMless (80C550 has no program memory on-chip), a 128 × 8 RAM, 8 channels of 8-bit A/D, four 8-bit ports (port 1 is input only), a watchdog timer, two 16-bit counter/timers, a seven-source, two-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and an on-chip oscillator and clock circuits.FEATURES\n• 80C51 based architecture\n   – 4k × 8 EPROM (87C550)/ROM (83C550)\n   – 128 × 8 RAM\n   – Eight channels of 8-bit A/D\n   – Two 16-bit counter/timers\n   – Watchdog timer\n   – Full duplex serial channel\n   – Boolean processor\n• Memory addressing capability\n   – 64k ROM and 64k RAM\n• Power control modes:\n   – Idle mode\n   – Power-down mode\n• CMOS and TTL compatible\n• One speed range at VCC = 5V ±10%\n   – 3.5 to 16MHz\n• Extended temperature ranges\n• OTP package available
