80C550/83C550/87C550 80C51 8-bit Microcontroller Family 4K/128 OTP/ROM/ROMless, 8 Channel 8 Bit A/D, Watchdog Timer

The 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. The 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. In addition, the 8XC550 has two software selectable modes of power reductionidle mode and power-down mode. The idle mode freezes the CPU while allowing the RAM, Timers serial port, and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the Oscillator causing all other chip functions to be inoperative.
