Renesas 89HPEB383ZBEMGI

Overview

89HPEB383ZBEMGI from Integrated Device Technology is a PCIe-to-PCI bridge evaluation board based on the PEB383 QFP device, implementing a single-lane PCIe 1.1 riser card with four 32-bit PCI slots operating at 25–66 MHz, supporting hot insertion, ATX and PCIe system power sourcing, and featuring JTAG debug headers, logic analyzer test points, and configurable clocking via DIP switches and shunt jumpers.

For engineers reviewing the 89HPEB383ZBEMGI datasheet, 89HPEB383ZBEMGI pinout, 89HPEB383ZBEMGI application, or 89HPEB383ZBEMGI equivalent, this page provides verified board-level specifications, power sequencing details, PCIe/PCI interface validation, clock multiplexing options, and hardware reset implementation for PCIe bridge evaluation and interoperability testing.

Technical Context

The 89HPEB383ZBEMGI implements a PCIe 1.1 x1 link (2.5 Gbps) interfacing with up to four 32-bit PCI slots compliant with PCI Specification 3.0, using a PEB383 bridge IC in LQFP package. It supports both master (bridge-generated) and slave (external oscillator) PCI clocking modes, and dual PCIe reference clock sources - system edge connector (100 MHz HCSL) or on-board PLL.

Power architecture includes independent regulation of 1.0V core (DC/DC), 3.3V PCIe AVDD (passive filter), 3.3V PCI I/O (power switch + optional ferrite), and auxiliary 5V/12V rails derived from ATX or PCIe slot. Hardware reset supports cold (PERST#), warm (push-button), and hot (in-band message) levels per PCIe specification.

FAQ

What is the primary function of the 89HPEB383ZBEMGI evaluation board?

The 89HPEB383ZBEMGI evaluation board is a hardware platform for validating the PEB383 PCIe-to-PCI bridge IC. It enables functional testing of PCIe 1.1 x1 to 32-bit PCI translation, clock domain bridging, power management behavior, and interoperability with PCI cards across four slots - all within a standardized riser card form factor compatible with ATX chassis and PCIe systems.

Does the 89HPEB383ZBEMGI support hot-plug operation for PCI cards?

Yes, the 89HPEB383ZBEMGI supports hot insertion and removal of PCI cards as defined in the PCI Local Bus Specification 3.0. The board provides appropriate power sequencing, signal integrity design, and mechanical clearance for up to four PCI cards in an open-chassis ATX environment, with dedicated pull-up networks and interrupt routing per slot.

How is PCIe reference clocking configured on the 89HPEB383ZBEMGI?

The 89HPEB383ZBEMGI offers dual PCIe reference clock sources: system-supplied 100 MHz HCSL via the PCIe edge connector, or an on-board 100 MHz clock generated by a PLL. Selection is controlled by DIP switch S5 (pins 3 and 4), with analog multiplexing ensuring clean domain separation between root complex and bridge clock domains.

What power architectures does the 89HPEB383ZBEMGI support?

The 89HPEB383ZBEMGI supports two mutually exclusive power topologies: PCIe slot-sourced (12V/3.3V only, up to ~23W net after regulator losses) or ATX 20-pin sourced (full 12V/5V/3.3V/-12V, enabling full 25W per PCI slot). An ATX presence detection circuit automatically disables PCIe slot power when external ATX is active.

Can the 89HPEB383ZBEMGI be used to validate PEB383 register configuration via JTAG?

Yes, the 89HPEB383ZBEMGI includes a standard 16-pin JTAG header (J22) with TDI, TDO, TCK, and TMS signals routed directly from the PEB383 device. This allows full boundary-scan testing, register read/write access, and firmware programming using industry-standard JTAG tools and IDT's JTAG Register Access Software Application Note.
