MC44BS374T1AEF datasheet by Freescale Semiconductor

MC44BS374T1AEF Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the MC44BS374T1AEF?
  The recommended operating voltage range for the MC44BS374T1AEF is 2.7V to 5.5V, with a typical voltage of 3.3V.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) in the MC44BS374T1AEF?
  The MC44BS374T1AEF has an internal POR and BOR circuitry. The POR is triggered when the power supply voltage falls below 1.5V, and the BOR is triggered when the power supply voltage falls below 2.2V. To handle these resets, ensure that your system design includes a proper power-up sequence and voltage monitoring.
• What is the maximum clock frequency supported by the MC44BS374T1AEF?
  The MC44BS374T1AEF supports a maximum clock frequency of 20 MHz.
• How do I configure the MC44BS374T1AEF for low-power operation?
  To configure the MC44BS374T1AEF for low-power operation, use the Power-Down Mode (PD) and the Stop Mode (STOP). In PD mode, the CPU clock is stopped, and the device consumes minimal power. In STOP mode, the CPU clock and peripherals are stopped, and the device consumes even lower power.
• What is the purpose of the internal oscillator in the MC44BS374T1AEF?
  The internal oscillator in the MC44BS374T1AEF is a 4 MHz oscillator that can be used as a clock source for the device. It can be used in conjunction with an external crystal or ceramic resonator to provide a stable clock signal.
