88P8344BHGI

Specialized ICS Overview

The Renesas Electronics Corporation IDT88P8344BHGI is a specialized interface IC functioning as an SPI exchange device. It facilitates data transfer between four OIF SPI-3 interfaces and one OIF SPI-4 phase 2 interface. The component supports logical port mapping, configurable memory allocation, and fragment/burst lengths ranging from 16 to 256 bytes. It operates within the industrial temperature range and utilizes an 820-ball BGA package.

Specialized ICS Feature Summary

• Four SPI-3 interfaces (8 or 32 bit, 19.44-133 MHz) and one SPI-4 phase 2 interface (80-400 MHz)
• Supports up to 64 concurrently active logical ports per SPI-3 interface and 256 for SPI-4
• Includes full suite of performance monitoring counters for packets, fragments, errors, and bytes
• Features IEEE 1149.1 JTAG and serial/parallel microprocessor control interfaces

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
