Integrated Device Technology IDT88P8344
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). The data that enter on the high speed interface (SPI-4) are mapped to logical identifiers (LIDs) and enqueued for transmission over a low speed interface (SPI-3).| Part No. | IDT88P8344 |
