RN2903FE(TE85L,F) - Toshiba

RN2903FE(TE85L,F) Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad is recommended under the IC to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are also recommended.
• How do I ensure reliable operation across the entire operating temperature range?
  Ensure that the device is operated within the recommended voltage and current ranges, and that the PCB is designed to minimize thermal gradients and voltage drops.
• What are the recommended decoupling capacitor values and placement?
  Use 0.1uF and 10uF decoupling capacitors, placed as close to the IC as possible, with the 0.1uF capacitor connected between VCC and GND, and the 10uF capacitor connected between AVCC and AGND.
• How do I handle ESD protection for this device?
  Use ESD protection devices such as TVS diodes or ESD arrays on the input/output lines, and ensure that the PCB is designed with ESD protection in mind, including the use of ESD-resistant components.
• What are the recommended settings for the internal voltage regulator?
  The internal voltage regulator is set to 1.8V by default, but can be adjusted to 1.2V or 1.5V using external resistors. Consult the datasheet for specific resistor values and configuration.
