  • Page 24: Adc/Pwm Interface

    The PWM output is a digital pulse-width modulated output. The output signal has a frequency of 6.75 kHz. An analogue signal is retrieved by low pass filtering outside the HW 86010. Please note that the reference voltage of the PWM output is V3P3. In order to reproduce exactly the analogue input voltage at ADC input, the PWM signal must be converted from V3P3 down to 2.5V prior to low pass filtering.

  • Page 26 Integration Manual HW 86010 3.4.6.3 Reset timing (external reset) In order to make sure that an external reset is detected correctly by the firmware, the host must pull RSTBI down sufficiently long time. The exact timing requirements are indicated in Figure 11.
  • Page 27 50ms Although it is triggered by the RSTBI signal the firmware of the HW 86010 treats a short reset as an internal reset. The host hardware may use this feature to emulate a power-up reset to the HW 86010.
  • Page 28 BOOT0 and BOOT1 are latched at the rising edge of RSTNO. The signals have internal 10 kΩ pull-ups. So they may be left unconnected, if not used. HW 86010 evaluates these signals on every reset (including internal resets). In order to avoid unwanted switches to firmware download mode, the host device shall take care that theses signals are driven low only together with RSTBI driven low.
  • Page 29 Please make sure that the following conditions are fulfilled during operation: V3P3 must not drop below 2,7V. This will trigger a low voltage reset. At power-up of the HW 86010 the RSTBI signal should be either high impedance (not connected) or logic HIGH. A logic LOW during power-up may be interpreted as external reset and may result in unwanted mode selection.

  • Page 30: I²C Interface

    The HW 86010 can only be operated as master device but not as slave device. The general concept of the I²C bus allows multiple master devices on the same bus. This is not supported by HW 86010, i.e. it must be the only master device on the bus. 3.4.7.3...
  • Page 31 Slave transmits Figure 13 I²C interface signal timing Data transfer is initiated by the master (HW 86010) when the bus is not busy, i.e. both data and clock lines are logic High. The master generates a Start condition, i.e. a High-to-Low transition of SDA while SCL is High.
  • Page 32 Integration Manual HW 86010 acknowledge related clock pulse, set-up and hold times must be taken into account. A master receiver must signal an end of data to the transmitter by not generating an acknowledge after the last byte that has been clocked out of the slave.

  • Page 40: Specific Integration Topics

    HW 86010 has a type approval according the European CTR 6 standard. This is a mandatory requirement for DECT equipment. When you integrate HW 86010 in your product, there is no need for doing the complete CTR 6 test again. Although it is not mandatory, Höft & Wessel recommends that you have your product checked in a shortened CTR 6 spot check.

    (max. 50mV). Note that all digital signals are 3.3V CMOS logic. In case you must interface to a 5V design take care: Inputs of HW 86010 are not 5V tolerant. The module will be damaged, if you connect its digital signals to 5V.
