PC87334VLJ General Description

The PC87334VLJ/PC87334VJG is a single chip solution for most commonly used I/O peripherals in ISA, EISA and MicroChannel É based computers. It incorporates 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. Standard PC-ATÉ address decoding for all the peripherals and a set of configuration registers are also implemented in this highly integrated member of the SuperI/O family. Advanced power management features, mixed voltage operation and integrated Serial-Infra- Red (SIR) support makes the PC87334 an ideal choice for low-power and/or portable personal computer applications.

The PC87334 FDC uses a high performance digital data separator eliminating the need for any external filter components. It is fully compatible with the PC8477 and incorporates a superset of DP8473, NEC mPD765 and N82077 floppy disk controller functions. All popular 5.25× and 3.5× floppy drives, including the 2.88 MB 3.5× floppy drive, are supported. In addition, automatic media sense and 2 Mbps tape drive support are provided by the FDC. The two UARTs are fully NS16450 and NS16550 compatible. Both ports support MIDI baud rates and one port also supports IrDA and the HP SIR compliant signaling protocol. The parallel port is fully IEEE 1284 level 2 compatible. The SPP (Standard Parallel Port) is fully compatible with ISA, EISA and MicroChannel parallel ports. In addition to the SPP, EPP (Enhanced Parallel Port) and ECP (Extended Capabilities Port) modes are supported by the parallel port. All IDE control signals with DMA support are provided by the
PC87334. Only external signal buffers are required to implement
a complete IDE interface.
