DESCRIPTION
Philips epitaxial substrate minimizes CMOS latch-up sensitivity. The 8XC751 contains a 2k × 8 ROM (83C751) EPROM (87C751), a 64 × 8 RAM, 19 I/O lines, a 16-bit auto-reload counter/timer, a five-source, fixed-priority level interrupt structure, a bidirectional inter-integrated circuit (I2C) serial bus interface, and an on-chip oscillator. The on-board inter-integrated circuit (I2C) bus interface allows the 8XC751 to operate as a master or slave device on the I2C small area network. This capability facilitates I/O and RAM expansion, access to EEPROM, processor-to-processor communication, and efficient interface to a wide variety of dedicated I2C peripherals.
