This document is an introduction manual for HPC3130A PCI hot-plug controller
The Texas Instruments HPC3130A is a PCI hot‑plug controller compliant with PCI Hot‑Plug Specification Revision 1.0. It enables non‑interfering hot‑plug insertion and removal of up to four slots on a PCI bus and includes automatic bus connection sequencing and ACPI‑compatible interrupt reporting.
The device offers both a generic parallel bus and a two‑wire serial interface for register access, supports 66 MHz PCI clock frequencies, provides a 64‑bit data path per slot, and is available in 120‑pin QFP, 128‑pin LQFP, and 144‑pin LQFP packages. Detailed pin assignments, electrical characteristics, and mechanical data are included in the following sections.
| Maximum hot‑plug slots | Four |
|---|---|
| PCI clock frequency support | 66 MHz |
| Package options | 120‑pin QFP, 128‑pin LQFP, 144‑pin LQFP |
| Register access interfaces | Generic parallel bus and two‑wire serial interface |
It supports up to four independently controlled hot‑plug slots.
The controller supports a PCI clock frequency of 66 MHz.
The device is offered in 120‑pin QFP, 128‑pin LQFP, and 144‑pin LQFP packages.
Registers can be accessed via a generic parallel bus or a two‑wire serial interface.
