88P8341BHGI

Specialized ICS Overview

The IDT88P8341 is a System Packet Interface (SPI) Exchange device manufactured by Renesas Electronics Corporation, originally produced by Integrated Device Technology. It facilitates data exchange between low-speed SPI-3 interfaces and high-speed SPI-4 interfaces. The device supports OIF SPI-3 at 19.44-133 MHz and one OIF SPI-4 phase 2 interface operating from 80 to 400 MHz. Each interface accommodates up to 64 concurrently active logical ports with a 256-address range. Key features include configurable memory allocation per logical port, fragment and burst length settings ranging from 16 to 256 bytes, and comprehensive performance monitoring counters for packets, fragments, errors, and bytes.

Specialized ICS Feature Summary

• Supports bidirectional exchange between OIF SPI-3 (19.44-133 MHz) and SPI-4 Phase 2 (80-400 MHz) standards.
• Provides 64 concurrently active logical ports per interface with dynamic LID mapping and configurable buffer memory.
• Includes full suite of performance monitoring counters for packet, fragment, error, and byte statistics.
• Features automatic bit alignment and lane de-skew for SPI-4 ingress LVDS signals.

Specialized ICS Applications

• Ethernet transport systems
• SONET/SDH packet transport line cards
• Broadband aggregation equipment
• Multi-service switches
• IP services equipment

Specialized ICS Procurement Notes

Verify component status as the product is listed as obsolete or discontinued in distributor databases. Confirm availability through authorized channels or secondary markets. Check for RoHS compliance details and specific manufacturing lot dates if required for legacy system maintenance. Ensure compatibility with existing PCB layouts due to the 820-TEBGA package dimensions.

Specialized ICS Selection Notes

Select this component when interfacing legacy SPI-3 network processors with modern SPI-4 networks. Ensure the design supports the required clock frequencies up to 400 MHz for SPI-4 operations. Verify that the host microprocessor can handle the serial or parallel control interface for configuration. Consider thermal management requirements for the exposed pad TEBGA package in dense applications.

Specialized ICS Part Context

This part was originally manufactured by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. The datasheet revision indicates an April 2006 publication date. The device serves as a bridge in telecommunications infrastructure, allowing seamless protocol translation and data routing between different generations of packet interface standards.

Specialized ICS Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the device is discontinued, engineers should evaluate newer Renesas SPI exchange solutions or generic FPGA implementations for protocol conversion if pin-to-pin compatible alternatives are not explicitly documented.
