The PC87306 is a single chip solution incorporating a Keyboard and PS/2É Mouse Controller (KBC), Real Time Clock(RTC) and most commonly used I/O peripherals in ISA, EISA and MicroChannelÉ 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-ATÉ address decoding for all the peripherals, a set of configuration registers, and two user selectable chip selects are also implemented in PC87306 highly integrated member of the SuperI/O family. The advanced features and high integration of the PC87306 result in several benefits for low cost, high performance systems. Printed circuit board space savings, fewer components on the motherboard and compatibility 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 microcontroller. PC87306 contains system timing, control logic, custom ROM program memory, RAM data memory and 18 programmable I/O lines of PC87306 necessary to implement dedicated control functions. It is an efficient controller which uses predominantly single byte instructions with support for binary and BCD arithmetic and extensive bit handling capabilities.
