1N705A [Microchip]

The HPC3130A supports hot insertion/removal of up to four hot-plug slots on a PCI bus, provides a 64-bit data path in any of the four hot-plug slots, and supports 66-MHz systems for two slots. It provides automatic bus connection sequencing and supports a protocol for connection during bus idle conditions. The device supports an interrupt pin to report hot-plug slot events, and the interrupt event status and enable state are compliant with ACPI Specification 1.0. Internal registers are accessible through both a two-signal serial interface and a generic parallel bus. The serial interface supports up to eight controllers, and the parallel interface supports multiple controllers with external chip-select logic. Two double-words of configuration and control registers are provided per slot, decoding an address range of 32 bytes. The device is fabricated in an advanced low-power CMOS process and features a CBT switch control feature for REQ64 implementation. Package options include 120-pin QFP, 128-pin LQFP, and 144-pin LQFP.
