MC44BS373CAEFR2 datasheet by Freescale Semiconductor

MC44BS373CAEFR2 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the MC44BS373CAEFR2?
  The recommended operating voltage range for the MC44BS373CAEFR2 is 2.7V to 5.5V, with a typical voltage of 3.3V.
• How do I configure the I2C bus speed on the MC44BS373CAEFR2?
  The I2C bus speed on the MC44BS373CAEFR2 can be configured by setting the SCL clock frequency using the I2C clock control register (I2C_CCR). The device supports standard-mode (100 kHz), fast-mode (400 kHz), and high-speed mode (1.7 MHz) I2C bus speeds.
• What is the maximum current rating for the MC44BS373CAEFR2?
  The maximum current rating for the MC44BS373CAEFR2 is 20mA per pin, with a total device current rating of 100mA.
• How do I handle interrupts on the MC44BS373CAEFR2?
  The MC44BS373CAEFR2 has a dedicated interrupt pin (INT) that can be configured to trigger on specific events, such as I2C bus errors or data ready interrupts. Interrupt handling requires setting up the interrupt enable register (IER) and interrupt status register (ISR) accordingly.
• Is the MC44BS373CAEFR2 compatible with 5V systems?
  While the MC44BS373CAEFR2 can operate at 5V, it's not recommended to use it in 5V systems without proper voltage regulation and level shifting, as the device's internal logic operates at 3.3V. Using a voltage regulator and level shifter can ensure compatibility with 5V systems.
