XIO2200AZHH datasheet by Texas Instruments

XIO2200AZHH Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the XIO2200AZHH datasheet (Section 10.1) and in the XIO2200A Evaluation Module User's Guide (SLUUAC6). It's essential to follow these guidelines to minimize noise, ensure proper signal integrity, and optimize performance.
• How do I configure the XIO2200AZHH for I2C or SPI mode?
  The XIO2200AZHH can be configured for I2C or SPI mode through the MODE pin (Pin 15). For I2C mode, connect the MODE pin to VCC, and for SPI mode, connect it to GND. Additionally, the device's configuration registers can be programmed to select the desired interface mode.
• What is the maximum clock frequency supported by the XIO2200AZHH?
  The XIO2200AZHH supports clock frequencies up to 50 MHz in I2C mode and up to 25 MHz in SPI mode. However, the actual clock frequency may be limited by the system's noise tolerance, signal integrity, and other factors.
• How do I handle the XIO2200AZHH's power-on reset (POR) and brown-out reset (BOR) features?
  The XIO2200AZHH has an internal POR and BOR circuitry that resets the device during power-up or brown-out conditions. To handle these features, ensure that the power supply is stable and within the recommended operating range. Additionally, consider adding external reset circuitry or using a supervisory circuit to monitor the power supply and generate a reset signal if necessary.
• What is the XIO2200AZHH's operating temperature range?
  The XIO2200AZHH is specified to operate over a temperature range of -40°C to 85°C (industrial grade) or -40°C to 125°C (extended grade). Ensure that the device is operated within the recommended temperature range to maintain its performance and reliability.
