82443MX

      The intel 82443MX PCIset (440MX) is designed as a single-component mobile chipset, 82443MX is optimized for intel mobile celeron processors and pentium II processors for new value and mini notebook platforms.The 440MX reduces the number of mobile chipset components without requiring any major programming model changes. It accomplishes this by integrating the 443BX North Bridge chipset (without AGP) and the PIIX4E south bridge chipset while adding a two-channel, digital AC'97 link feature.
      82443MX has many features.It would have processor / host bus support, integrated DRAM controller, PCI Bus interface, PCI arbiter, CPU bus arbiter, DRAM arbitration for managing multiple request queues, internal DRAM controller arbitration between data requests and refresh requests, system peripherals, AC'97 link controller (2 channels), GPIO pins (31), 1 channel bus master IDE support ATA33, X-bus support, SMBus, power management functions and system management.
      There are some important signal about 82443MX.For its USB signal, its OC[1:0]# would means overcurrent indicators. These signals set corresponding bits in the USB controller to indicate that an overcurrent condition has occurred.Its USBPRT[0]+ and USBPRT[0]- would means universal serial bus port 0 differential. bus data / address / command bus.Its USBPRT[1]+ and USBPRT[1]- would means universal serial bus port 1 differential. Bus data / address / command bus.For the SMBus signal its SMBCLK would means SMBus clock. SMBus clock pin. external pullup required.Its SMBDATA would means SMBus data. SMBus Data pin. external pullup required.For its power management signal its BATLOW# / GPIO(11) would means battery low. This signal is on the resume plane. If the battery low function is not needed, then this signal is used as a general-purpose I/O pin.Its CPUSTP# would means stop CPU clock. This signal is an output to the external clock generator to turn off the processor and memory clocks. This is done prior to entering the C3 state, as well as the S1 and S2 states.And so on.For more information please contact us.
