PC87332VLJ (3.3V/5V) General Description
The PC87332VLJ and PC87332VLJ-5 are single chip solutions for most commonly used I/O peripherals in ISA, EISA and MicroChannelÉ 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 and mixed voltage operation in the VLJ version make the PC87332 chips an ideal for low-power and/or portable personal computer applications.
The PC87332 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.
