AT21CS11-STU10-T Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the AT21CS11-STU10-T is -40°C to +85°C.
  • The AT21CS11-STU10-T can be configured for I2C or SPI mode by setting the MODE pin high or low, respectively, during power-up. For I2C mode, the MODE pin should be connected to VCC, and for SPI mode, it should be connected to GND.
  • The AT21CS11-STU10-T supports clock frequencies up to 10 MHz in I2C mode and up to 20 MHz in SPI mode.
  • The AT21CS11-STU10-T supports secure boot through its built-in cryptographic engine and secure boot mechanisms. Implementing a secure boot process involves generating a secure boot image, storing it in the device, and configuring the device to boot securely.
  • The AT21CS11-STU10-T is designed to operate from a 1.8V to 3.3V power supply. It is not recommended to use it with a 5V power supply, as it may exceed the maximum rating and cause damage to the device.
