Overview: PC87303VUL SuperI O Sidewinder Lite Floppy Disk Controller Keyboard Controller Real-Time Clock Dual UARTs IEEE 1284 Parallel Port and IDE Interface PRELIMINARY February 1995 PC87303VUL SuperI O TM Sidewinder Lite Floppy.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The PC87303VUL is a single chip solution incorporating a Keyboard and PS 2 Mouse Controller (KBC) Real Time Clock (RTC) and most monly used I O peripherals in ISA EISA and MicroChannel based puters In addition to the KBC and RTC a Floppy Disk Controller (FDC) two full featured UARTs an IEEE 1284 patible parallel port and all the necessary control logic for an IDE interface provides support for most monly 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 SuperI O family The advanced

Key Features

  • and high integration of the PC87303 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 PC87303 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.
