W_Disable# signal to disable radio operation. There are several GPIO pins (2.6V compatible) reserved for customized applications, please contact BandRich for discussion. Besides the above mentioned interfaces, M250V also provides PCM interfaces reserved for voice applications. The M250-LC features low power consumption but requires higher input voltage than PCI standard.

Figure 1-3 Pin-out information of M250 series (Top View) Network LED indicate device The Network LED indicated device is ground-referenced current sink. The host drives the device to provide a current path and an appropriate voltage for LED at PIN 42 of M250 module. Figure 2-2 shows the block diagram of the current drivers.

USB Interface M250, M250V and M250-LC module are compliant with USB2.0 in all three modes (Low speed, Full speed, and high speed). When two devices are connected via a USB interface, one of the devices must act as a host, and the other device must act as a peripheral. The host is responsible for initiating and controlling traffic on the bus.

USIM_CLK and USIM_RST signal, include 33pF filter capacitors is required to be placed near the SIM connector. Route all USIM signals carefully – isolate them from sensitive analog and RF signals. External ESD diodes are necessary to protect the chip on the module; the ESD diodes should be placed near the connector.

Section 2 Device Driver Interface Basically the module will manifest itself as a composite USB device which creates stubs which the other higher level drivers hook into and provide their respective function. The composite USB device could be modem, NDIS interface, AT command interface or diagnostics interface. All device drivers used by OS have been created for Microsoft Windows Vista 32/64, Windows XP SP2 above, Windows 2000 SP4 above, Mac OSX 10.4 above, and Linux Fedora 8, Unbuntu 7, Open SuSE 10.
