TS921ID datasheet by STMicroelectronics

TS921ID Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the TS921ID?
  The recommended operating voltage range for the TS921ID is 2.7V to 5.5V, with a typical operating voltage of 3.3V.
• How do I configure the TS921ID for I2C or SPI interface?
  The TS921ID 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 data transfer rate for the TS921ID?
  The maximum data transfer rate for the TS921ID is 400 kHz for I2C mode and 10 MHz for SPI mode.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) features of the TS921ID?
  The TS921ID has an internal POR and BOR circuitry that resets the device during power-up or brown-out conditions. No external components are required, but a capacitor on the VCC pin is recommended to filter out noise.
• Can I use the TS921ID in a noisy environment?
  Yes, the TS921ID has built-in electromagnetic interference (EMI) and radio-frequency interference (RFI) filters, making it suitable for use in noisy environments.
