Cinterion® EHS6-A Hardware Interface Overview Page 16 of 40 2.1 Application Interface 22 2.1.7 GPIO Interface EHS6-A offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other interfaces or functions: Fast shutdown (see Section 2.1.14), status LED (see Section 2.1.13), the PWM functionality (see Section 2.1.11), an pulse counter (see Section 2.1.12), ASC0 (see Section 2.1.2), ASC1 (see Section 2.1.3), an SPI interface (see Section 2.1.9), an HSIC interface (see Section 2.1.
Cinterion® EHS6-A Hardware Interface Overview Page 17 of 40 2.1 Application Interface 22 2.1.8 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® EHS6-A Hardware Interface Overview Page 18 of 40 2.1 Application Interface 22 2.1.11 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 2.1.7). GPIO and PWM functionality are mutually exclusive. 2.1.
Cinterion® EHS6-A Hardware Interface Overview Page 19 of 40 2.2 RF Antenna Interface 22 2.2 RF Antenna Interface The RF interface has an impedance of 50. EHS6-A 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® EHS6-A Hardware Interface Overview Page 20 of 40 2.2 RF Antenna Interface 22 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 EHS6-A. All RF data specified throughout this document is related to the ARP.
Cinterion® EHS6-A Hardware Interface Overview Page 21 of 40 2.3 Sample Application 22 2.3 Sample Application Figure 6 shows a typical example of how to integrate a EHS6-A module with an application. Usage of the various host interfaces depends on the desired features of the application. The analog audio interface demonstrates the balanced connection of microphone and earpiece. This solution is particularly well suited for internal transducers.
