EHS5-E/EHS5-US Hardware Interface Overview 2 Interface Characteristics 18 2 Interface Characteristics EHS5-E/EHS5-US is equipped with an SMT application interface that connects to the external application. The SMT application interface incorporates the various application interfaces as well as the RF antenna interface. 2.1 Application Interface 2.1.1 USB Interface EHS5-E/EHS5-US supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) compliant.
EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 While the USB connection is active, the module will not change into SLEEP Mode. To enable switching into SLEEP mode the USB host must bring its USB interface into Suspend state. Also, VUSB_IN should always be kept enabled for this functionality. See “Universal Serial Bus Specification Revision 2.0“1 for a description of the Suspend state.
EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 • • • • • • The RING0 signal serves to indicate incoming calls and other types of URCs (Unsolicited Result Code). It can also be used to send pulses to the host application, for example to wake up the application from power saving state. Configured for 8 data bits, no parity and 1 stop bit. ASC0 can be operated at fixed bit rates from 1200bps up to 921600bps. Autobauding supports bit rates from 1200bps up to 230400bps.
EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 2.1.4 UICC/SIM/USIM Interface EHS5-E/EHS5-US has an integrated UICC/SIM/USIM interface compatible with the 3GPP 31.102 and ETSI 102 221. This is wired to the host interface in order to be connected to an external SIM card holder. Five pads on the SMT application interface are reserved for the SIM interface. The UICC/SIM/USIM interface supports 3V and 1.8V SIM cards.
EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 The figure below shows a circuit to connect an external SIM card holder. V180 CCIN CCVCC SIM 220nF 1nF CCRST CCIO CCCLK Figure 5: External UICC/SIM/USIM card holder circuit The total cable length between the SMT application interface pads on EHS5-E/EHS5-US and the pads of the external SIM card holder must not exceed 100mm in order to meet the specifications of 3GPP TS 51.010-1 and to satisfy the requirements of EMC compliance.
EHS5-E/EHS5-US Hardware Interface Overview 2.1 Application Interface 18 Table 2: GPIO assignment GPIO PWM Status LED GPIO5 Status LED GPIO6 PWM2 GPIO7 PWM1 GPIO8 When the EHS5-E/EHS5-US starts up, all GPIO lines are set to high-impedance state after initializing. Therefore, it is recommended to connect external pull-up or pull-down resistors to all GPIO lines you want to use as output. This is necessary to keep these lines from floating or driving any external devices. 2.1.
EHS5-E/EHS5-US Hardware Interface Overview 2.2 RF Antenna Interface 18 2.2 RF Antenna Interface The RF interface has an impedance of 50. EHS5-E/EHS5-US is capable of sustaining a total mismatch at the antenna line without any damage, even when transmitting at maximum RF power. The external antenna must be matched properly to achieve best performance regarding radiated power, modulation accuracy and harmonic suppression.
EHS5-E/EHS5-US Hardware Interface Overview 2.3 Sample Application 18 2.3 Sample Application Figure 6 shows a typical example of how to integrate a EHS5-E/EHS5-US module with an application. Usage of the various host interfaces depends on the desired features of the application. Because of the very low power consumption design, current flowing from any other source into the module circuit must be avoided, for example reverse current from high state external control lines.
