SMTPA200 Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the SMTPA200?
  The recommended operating temperature range for the SMTPA200 is -40°C to 125°C.
• How do I configure the SMTPA200 for I2C or SPI interface?
  The SMTPA200 can be configured for I2C or SPI interface by setting the MODE pin high or low, respectively. For I2C, connect MODE to VCC, and for SPI, connect MODE to GND.
• What is the maximum frequency for the clock input on the SMTPA200?
  The maximum frequency for the clock input on the SMTPA200 is 50 MHz.
• How do I reset the SMTPA200?
  The SMTPA200 can be reset by pulling the RESET pin low for at least 10 ns. The device will reset to its default state after the RESET pin is released.
• What is the power consumption of the SMTPA200?
  The power consumption of the SMTPA200 depends on the operating mode and frequency. In active mode, the typical current consumption is 1.5 mA at 1.8 V and 25°C. In standby mode, the typical current consumption is 1 μA at 1.8 V and 25°C.
