PC87306 - Floppy Disk Controller / Keyboard Controller

Download the PC87306 datasheet PDF. This datasheet also covers the PC8 variant, as both devices belong to the same floppy disk controller / keyboard controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The PC87306 is a single chip solution incorporating a Keyboard 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

Key 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 It contains system timing control logic custom ROM program memory RAM data memory and 18 programmable I O lines necessary to implement dedicated.
