IDT88P8344 - SPI EXCHANGE

Description

The IDT88P8344 is a SPI (System Packet Interface) Exchange with four SPI3 interfaces and one SPI-4 interface.

The data that enter on the low speed interface (SPI-3) are mapped to logical identifiers (LIDs) and enqueued for transmission over the high speed interface (SPI-4).

Features

  • IDT88P8344 Functionality - Low speed to high speed SPI exchange device - Logical port (LP) mapping (SPI-3 SPI-4) tables per direction - Per LP configurable memory allocation - Maskable interrupts for fatal errors - Fragment and burst length configurable per interface: min 16 bytes, max 256 bytes.
  • Standard Interfaces - Four OIF SPI-3: 8 or 32 bit, 19.44-133 MHz, 256 address range, 64 concurrently active LPs per interface - One OIF SPI-4 phase 2: 80 - 400 MHz, 256 address.
