Renesas 89HPEB383ZAEM

Overview

89HPEB383ZAEM from Integrated Device Technology, Inc. is a transparent x1 PCI Express to 32-bit/66 MHz PCI bridge IC supporting plug-and-play BIOS enumeration, ultra-low standby power (130 mW), 128-byte PCIe max payload, and 5V-tolerant PCI I/O with VIO pins. It enables legacy PCI expansion on modern PCIe-based motherboards and DVR adapter cards.

For engineers reviewing the 89HPEB383ZAEM datasheet, 89HPEB383ZAEM pinout, 89HPEB383ZAEM application, or 89HPEB383ZAEM equivalent, key selection criteria include transparent/non-transparent bridging mode support, PCIe 1.1 & PCI 3.0 compliance, ASPM L0s/L1 power states, 1-KB PCI read completion buffer, and 10×10 mm 132-pin QFN package compatibility with 4-layer PCB routing.

Technical Context

The 89HPEB383ZAEM implements a dual-domain bridge architecture with independent PCIe and PCI transaction layers, supporting both transparent forwarding and non-transparent address remapping. It integrates a 4-master PCI arbiter and supports subtractive decode for legacy cycle forwarding.

PCIe interface complies with Base Spec 1.1 and includes Advanced Error Reporting (AER), end-to-end CRC (ECRC), up to four outstanding memory reads, and 512-byte read completion buffer. PCI interface meets Local Bus Spec 3.0 with 66 MHz operation, 5V-tolerant I/O, and 1-KB read completion buffer.

Key Specifications

Pinout & Package

FAQ

Is the 89HPEB383ZAEM a transparent or non-transparent bridge?

The 89HPEB383ZAEM supports both transparent and non-transparent bridging modes. In transparent mode, it enables flow-through PCI enumeration and memory-mapped I/O without address translation. In non-transparent mode, it performs address remapping between PCIe and PCI domains-ideal for isolated peripheral subsystems like set-top box tuner modules. Configuration is controlled via internal registers and EEPROM settings.

What power states does the 89HPEB383ZAEM support?

The 89HPEB383ZAEM supports D0 (fully active), D3hot (soft off with power maintained), and D3cold (hard off) states per PCI Power Management Specification 1.2, plus ASPM L0s and L1 link power states per PCIe 1.1. Its 130 mW standby power reflects operation in D3cold with auxiliary power applied-verified in IDT's PEB383 Product Brief (Jan 2010).

Does the 89HPEB383ZAEM support 5V-tolerant PCI I/O?

Yes, the 89HPEB383ZAEM supports 5V-tolerant PCI I/O through dedicated VIO pins (VIO_0–VIO_3), allowing direct connection to legacy 5V PCI buses without level-shifting circuitry. This feature enhances reliability and simplifies design in mixed-voltage systems such as motherboards interfacing with older PCI add-in cards.

What is the purpose of Short-Term Caching in the 89HPEB383ZAEM?

Short-Term Caching in the 89HPEB383ZAEM is a proprietary hardware acceleration feature that buffers recent PCIe read completions to accelerate repeated or sequential PCI read requests. As documented in the IDT PEB383 Product Brief, this delivers up to 5× higher read throughput-particularly beneficial in DVR adapter cards streaming data from multiple video decoders.

Can the 89HPEB383ZAEM be used in a 4-layer PCB design?

Yes, the 89HPEB383ZAEM's 10×10 mm 132-pin QFN package is explicitly designed for 4-layer PCB escape routing, as stated in the IDT PEB383 Product Brief. Its pinout and thermal pad layout minimize trace congestion and reduce layer count requirements-lowering manufacturing cost and improving signal integrity for high-speed PCIe and PCI buses.
