NH82801EB SL7YC

The NH82801EB SL7YC is designed as the intel I/O controller hub 5 (ICH5). NH82801EB SL7YC incorporates a variety of PCI functions that are divided into four logical devices (B0:D30, B0:D31, B0:D29 and B1:D8). D30 is the hub interface-to-PCI bridge, D31 contains the PCI-to-LPC bridge, IDE controller, SATA controller, SMBus controller and the AC 97 audio and modem controller functions and D29 contains the four USB UHCI controllers and one USB EHCI controller. B1:D8 is the integrated LAN controller.

NH82801EB SL7YC has many features and some are listed here. (1) PCI bus interface which means supports PCI revision 2.3 specification at 33MHz, 6 available PCI REQ/GNT pairs and one PCI REQ/GNT pair can be given higher arbitration priority (intended for external 1394 host controller), support for 44-bit addressing on PCI using DAC protocol. (2) Integrated LAN controller. (3) Integrated serial ATA host controllers. (4) Integrated IDE controller. (5) USB 2.0. (6) AC-Link for audio and telephony codecs. (7) Interrupt controller. (8) High-precision event timers. (9) 1.5V operation with 3.3V I/O. (10) Timers based on 82C54. (11) Integrated 1.5V voltage regulator (INTVR) for the suspend wells. And so on.

Some DC input characteristics of NH82801EB SL7YC have been concluded into several points as follow. (1) Its input low voltage VIL1 would be min -0.5V and max 0.3Vcc3_3. (2) Its input high voltage VIH1 would be min 0.5Vcc3_3 and max V5REF + 0.5V. (3) Its input low voltage VIL2 would be min -0.5V and max 0.8V. (4) Its input high voltage VIH2 would be min 2.0V and max V5REF + 0.5V. (5) Its input low voltage VIL3 would be min -0.5V and max 0.8V. (6) Its input high voltage VIH3 would be min 2.0V and max Vcc3_3 + 0.5V. (7) Its low to high input threshold would be min 1.5V and max 2.0V. (8) Its high to low input threshold would be min 1.0V and max 1.5V. (9) Its differential input sensitivity would be min 0.2V. (10) Its differential common mode range would be min 0.8V and max 2.5V. (11) Its single-ended receiver threshold would be min 0.8V and max 2.0V. And so on.
