BlueMod+B20 Stollmann Hardware reference E + V GmbH 3 Application Interface 3.1 Power Supply The BlueMod+B20 requires a power supply with the following characteristics: 3.3V ± 0.1V low noise (≤10mV) >80mA peak Due to the technological requirements and the pulsed radio transmission the supply needs to be fed by an ultra fast (response time ≤20µs) linear regulator placed as close as possible to the VSUP pin (22).
BlueMod+B20 Stollmann Hardware reference E + V GmbH 3.2 Reset The BlueMod+B20 is equipped with circuitry for generating Power Down Reset from the internal core voltage. A reset is generated when the core voltage falls below typically 1.5V and is released when it rises above typically 1.6V. Via Pin 31 an external reset is generated by holding RESET# at ≤ 0.3V for ≥ 5ms. It is strongly recommended to use external Power ON Reset circuitry, which holds RESET# at ≤ 0.
BlueMod+B20 Stollmann Hardware reference E + V GmbH 3.3 Serial Interface The interface functionally corresponds to V.24 / RS-232 but has TTL-level. • Transmission speeds 1200 – 2764800 bps (asynchronous) • Character representation: 8 Bit, even/odd/no Parity, 1 or 2 stop bits • hardware flow-control with UART_RTS and UART_CTS (active low) RXD BlueMod+B20 Host TXD CTS RTS 3.
BlueMod+B20 Stollmann Hardware reference E + V GmbH 3.5 I2C Interface PIO[8:6] can be used to form a master I2C interface. The interface is formed using software to drive these lines. Therefore, it is suited only to relatively slow functions i.e. EEPROM. +1.8V PIO[8] PIO[6] PIO[7] 2.2k 2.2k 2.2k 10nF VCC A0 WP A1 SCL A2 SDA GND Example EEPROM connection BluMod+B20 interfaces directly to EEPROM devices including the following: • • • • • • • • 3.
BlueMod+B20 Stollmann Hardware reference E + V GmbH 3.7 PCM Interface PCM or Pulse Code Modulation is a sampling technique for digitising analogue signals. The PCM interface for voice applications is provided via the PCM_OUT, PCM_IN, PCM_CLK and PCM_SYNC pins. The PCM interface can act as master or as slave device. In master mode, clock frequencies of 128kHz, 256kHz or 512kHz can be generated, when using the internal 4MHz clock. In slave mode, clock frequencies up to 2048kHz are accepted.
BlueMod+B20 Stollmann Hardware reference E + V GmbH 3.8.3 USB Self-Powered Mode In USB self-powered mode, the BlueMod+B20 is powered from its own power supply and not from the USB Vbus line. In order to detect when the USB Vbus line is powered up, the USB Vbus line is monitored by PIO4 through a voltage divider .
