描述 Description

The PC87306 is a single chip solution incorporating a Key-board and PS/2* Mouse Controller(KBC), Real Time Clock (RTC) and most commonly used I/O peripherals in ISA, EISA and MicroChannel* based computers. In addition to the KBC and RTC,a Floppy Disk Controller(FDC). two full featured UARTs, an IEEE 1284 compatible parallel port and all the necessary control logic for an IDE interface provides support for most commonly used I/O peripherals. Standard PC-AT address decoding for all the peripherals,a set of configuration registers, and two user selectable chip selects are also implemented in this highly integrated member of the Superl/O family. The advanced features and high inte-gration of the PC87306 result in several benefits for low cost, high performance systems. Printed circuit board space savings, fewer components on the motherboard and com-patibility with the latest industry standard peripherals are only a few of the benefits of using a PC87306.

The KBC is fully software compatible with the 8042AH mi-crocontroller. It contains system timing, control logic, cus-tom ROM program memory, RAM data memory and 18 pro-grammable l/O lines necessary to implement dedicated control functions. It is an efficient controller which uses pre-dominantly single byte instructions with support for binary and BCD arithmetic and extensive bit handling capabilities.
