NXP Semiconductors 83C576
83C576/87C576 is a high-performance microcontroller fabricated with Philips high-density CMOS technology. The Philips CMOS technology combines the high speed and density characteristics of HMOS with the low power attributes of CMOS. The 8XC576 contains an 8k × 8 ROM (83C576) EPROM (87C576), a 256 × 8 RAM, 32 I/O lines, three 16-bit counter/timers, a Programmable Counter Array (PCA), a 10-bit, 6 channel A/D, 2 PWM outputs, an 8-bit UPI interface, a fifteen-source, two-priority level nested interrupt structure, an enhanced UART, four analog comparators, power-fail detect and oscillator fail detect circuits, and on-chip oscillator and clock circuits.
