Cinterion® EHS8 Hardware Interface Overview Page 17 of 42 2.1 Application Interface 24 2.1.6 GPIO Interface EHS8 offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other interfaces or functions: Fast shutdown (see Section 2.1.13), status LED (see Section 2.1.12), the PWM functionality (see Section 2.1.10), an pulse counter (see Section 2.1.11), ASC0 (see Section 2.1.2), ASC1 (see Section 2.1.3), an SPI interface (see Section 2.1.8), an HSIC interface (see Section 2.1.
Cinterion® EHS8 Hardware Interface Overview Page 18 of 42 2.1 Application Interface 24 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.
Cinterion® EHS8 Hardware Interface Overview Page 19 of 42 2.1 Application Interface 24 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.
Cinterion® EHS8 Hardware Interface Overview Page 20 of 42 2.2 RF Antenna Interface 24 2.2 RF Antenna Interface The RF interface has an impedance of 50. EHS8 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.
Cinterion® EHS8 Hardware Interface Overview Page 21 of 42 2.2 RF Antenna Interface 24 2.2.1 Antenna Installation The antenna is connected by soldering the antenna pad (ANT_GSM, 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 EHS8. All RF data specified throughout this document is related to the ARP.
Cinterion® EHS8 Hardware Interface Overview Page 22 of 42 2.3 GPS Interface 24 2.3 GPS Interface 2.3.1 GPS Receiver EHS8 integrates a GPS receiver that offers the full performance of GPS technology. The GPS receiver is able to continuously track all satellites in view, thus providing accurate satellite position data. The integrated GPS receiver supports the NMEA protocol via ASC0 interface.
Cinterion® EHS8 Hardware Interface Overview Page 23 of 42 2.4 Sample Application 24 2.4 Sample Application Figure 6 shows a typical example of how to integrate a EHS8 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.
