89HPES16NT2 Datasheet | Renesas

Overview The 89HPES16NT2 is a member of the IDT PRECISE™ family of PCI Express® switching solutions offering the next-generation I/O interconnect standard. The PES16NT2 is a 16-lane, 2-port peripheral chip that provides high-performance switching and non-transparent bridging (NTB) functions between a PCIe® upstream port and an NTB downstream port. The PES16NT2 is a part of the IDT PCIe System Interconnect Products and is intended to be used with IDT PCIe System Interconnect Switches. Together, the chipset targets multi-host and intelligent I/O applications such as munications, storage, and blade servers where inter-domain munication is required. Features - High Performance PCI Express Switch - Sixteen PCI Express lanes (2.5Gbps), two switch ports - Delivers 64 Gbps (8 GBps) of aggregate switching capacity - Low latency cut-through switch architecture - Support for Max Payload size up to 2048 bytes - Supports one virtual channel and eight traffic classes - PCI Express Base specification Revision 1.0a pliant - Flexible Architecture with Numerous Configuration Options - Supports automatic per port link width negotiation (x8, x4, x2, or x1) - Static lane reversal on all ports - Automatic polarity inversion on all lanes - Supports locked transactions, allowing use with legacy software - Ability to load device configuration from serial EEPROM - Ability to control device via SMBus - Non-Transparent Port - Crosslink support on NTB port - Four mapping windows supported - Each may be configured as a 32-bit memory or I/O window - May be paired to form a 64-bit memory window - Interprocessor munication - Thirty-two inbound and outbound doorbells - Four inbound and outbound message registers - Two shared scratchpad registers - Allows up to sixteen masters to municate through the nontransparent port - No limit on the number of supported outstanding transactions through the non-transparent bridge - pletely symmetric non-transparent bridge operation allows similar/same...
