DS1866Z/T&R datasheet by Maxim Integrated Products

DS1866Z/T&R Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the DS1866Z/T&R?
  The recommended operating voltage range for the DS1866Z/T&R is 2.7V to 5.5V, although it can operate down to 2.2V with reduced performance.
• How do I ensure reliable communication between the DS1866Z/T&R and the microcontroller?
  To ensure reliable communication, make sure to use a pull-up resistor on the SCL line, use a clock frequency within the recommended range (100kHz to 400kHz), and implement proper I2C protocol timing and bus management.
• What is the maximum capacitance allowed on the SDA and SCL lines?
  The maximum capacitance allowed on the SDA and SCL lines is 400pF. Exceeding this value can cause signal distortion and communication errors.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) features of the DS1866Z/T&R?
  The POR and BOR features are enabled by default. To handle them, ensure that your microcontroller is designed to handle the reset signals and implement a proper power-up sequence to initialize the DS1866Z/T&R.
• What is the purpose of the internal EEPROM, and how do I use it?
  The internal EEPROM is used to store configuration data and calibration values. You can use it to store custom settings, calibration data, or other non-volatile information. Use the I2C interface to read and write data to the EEPROM.
