EHS6 Hardware Interface Overview 2 Interface Characteristics 21 2 Interface Characteristics EHS6 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 EHS6 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/ s) compliant.
EHS6 Hardware Interface Overview 2.1 Application Interface 21 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.
EHS6 Hardware Interface Overview 2.1 Application Interface 21 • • • • • 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 1,200bps up to 921,600bps. Autobauding supports bit rates from 1,200bps up to 230,400bps. Supports RTS0/CTS0 hardware flow control. The hardware hand shake line RTS0 has an internal pull down resistor causing a low level signal, if the line is not used and open.
EHS6 Hardware Interface Overview 2.1 Application Interface 21 2.1.4 UICC/SIM/USIM Interface EHS6 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.
EHS6 Hardware Interface Overview 2.1 Application Interface 21 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 EHS6 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.

EHS6 Hardware Interface Overview 2.1 Application Interface 21 2.1.7 I2C Interface I2C is a serial, 8-bit oriented data transfer bus for bit rates up to 400kbps in Fast mode. It consists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK. The module acts as a single master device, e.g. the clock I2CCLK is driven by the module. I2CDAT is a bi-directional line.
EHS6 Hardware Interface Overview 2.1 Application Interface 21 2.1.10 PWM Interfaces The GPIO6 and GPIO7 interface lines can be configured as Pulse Width Modulation interface lines PWM1 and PWM2. The PWM interface lines can be used, for example, to connect buzzers. The PWM1 line is shared with GPIO7 and the PWM2 line is shared with GPIO6 (for GPIOs see Section 2.1.6). GPIO and PWM functionality are mutually exclusive. 2.1.
EHS6 Hardware Interface Overview 2.2 RF Antenna Interface 21 2.2 RF Antenna Interface The RF interface has an impedance of 50. EHS6 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.
EHS6 Hardware Interface Overview 2.2 RF Antenna Interface 21 2.2.1 Antenna Installation The antenna is connected by soldering the antenna pad (RF_OUT, i.e., pad #59) and its neighboring ground pads (GND, i.e., pads #58 and #60) directly to the application’s PCB. The antenna pad is the antenna reference point (ARP) for EHS6. All RF data specified throughout this document is related to the ARP.
EHS6 Hardware Interface Overview 2.3 Sample Application 21 2.3 Sample Application Figure 6 shows a typical example of how to integrate a EHS6 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.
