BR24G04FVT-3AGE2 - ROHM Semiconductor

BR24G04FVT-3AGE2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the BR24G04FVT-3AGE2?
  ROHM recommends following a 4-layer PCB stack-up with a solid ground plane and a separate power plane for the VCC and VPP pins. Additionally, keep the signal traces short and away from noise sources, and use a 10nF decoupling capacitor between VCC and GND.
• How do I ensure reliable data retention in the BR24G04FVT-3AGE2?
  To ensure reliable data retention, follow the recommended storage conditions (e.g., temperature range, humidity), avoid exposing the device to radiation or electrostatic discharge, and use a suitable write protection mechanism to prevent accidental data modification.
• What is the maximum operating frequency for the BR24G04FVT-3AGE2?
  The maximum operating frequency for the BR24G04FVT-3AGE2 is 20MHz. However, it's recommended to consult the datasheet for specific frequency-related characteristics and to perform thorough testing to ensure reliable operation at higher frequencies.
• Can I use the BR24G04FVT-3AGE2 in a high-temperature environment?
  The BR24G04FVT-3AGE2 is rated for operation up to 85°C. However, it's essential to consider the device's reliability and data retention at elevated temperatures. Consult the datasheet and ROHM's application notes for guidance on using the device in high-temperature environments.
• How do I handle the BR24G04FVT-3AGE2's power-on reset (POR) and brown-out reset (BOR) features?
  The BR24G04FVT-3AGE2 has built-in POR and BOR features to ensure reliable startup and operation. To handle these features, ensure that the power supply ramps up slowly (typically 10ms or more) and that the VCC pin is properly decoupled. Consult the datasheet for specific guidelines on using these features.
