NH82801DBM SL7VK

The NH82801DBM SL7VK is designed as the intel I/O controller hub 4 mobile (ICH4-M). NH82801DBM SL7VK incorporates a variety of PCI functions that are divided into three logical devices (29, 30, and 31) on PCI bus 0 and one device on bus 1. Device 30 is the hub interface-to-PCI bridge. Device 31 contains all the other PCI functions, except the USB controllers and the LAN controller.

NH82801DBM SL7VK has many features and some are listed here. (1) PCI bus interface which means supports PCI revision 2.2 specification at 33MHz, 133 MB/sec maximum throughput, supports up to 6 master devices on PCI, one PCI REQ/GNT pair can be given higher arbitration priority (intended for external 1394 host controller) and support for 44-bit addressing on PCI using DAC protocol. (2) Integrated LAN controller. (3) Integrated IDE controller. (4) USB. (5) AC'97-link for audio and telephony codecs. (6) Interrupt controller. (7) 1.5V operation with 3.3V I/O. (8) Timers based on 82C54. (9) power management logic. (10) external glue integration. (11) Enhanced hub interface buffers improve routing flexibility (not available with all memory controller hubs). And so on.

Some absolute maximum ratings of NH82801DBM SL7VK have been concluded into several points as follow. (1) Its voltage on any 3.3V pin with respect to ground would be from -0.5 to Vcc3_3 + 0.5V. (2) Its voltage on any 5V tolerant pin with respect to ground (VREF=5V) would be from -0.5V to VREF + 0.5V. (3) Its 1.5V supply voltage with respect to Vss would be from -0.5V to +2.1V. (4) Its 1.8V supply voltage with respect to Vss would be from -0.5V to +2.1V. (5) Its 3.3V supply voltage with respect to Vss would be from -0.5V to +4.6V. (6) Its 5.0V supply voltage (Vref) with respect to Vss would be from -0.5V to +5.5V. It should be noted that stressing the device beyond the ''absolute maximum ratings'' may cause permanent damage. And so on. If you have any question or suggestion or want to know more information about NH82801DBM SL7VK please contact us for details. Thank you!
