AM3874BCYE100 datasheet by Texas Instruments

AM3874BCYE100 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the AM3874BCYE100?
  The recommended power-on sequence is to power up the core voltage (VDD_CORE) first, followed by the I/O voltage (VDD_MPU), and then the PLL voltage (VDD_PLL). This sequence helps prevent latch-up and ensures proper device operation.
• How do I optimize the AM3874BCYE100's power consumption?
  To optimize power consumption, use the device's power management features, such as dynamic voltage and frequency scaling (DVFS), clock gating, and power gating. Additionally, optimize your software to minimize idle time, use low-power modes, and reduce peripheral usage when not needed.
• What is the maximum operating temperature for the AM3874BCYE100?
  The maximum operating temperature for the AM3874BCYE100 is 90°C (Tj). However, it's recommended to operate the device within the specified temperature range (–40°C to 85°C) for optimal performance and reliability.
• How do I ensure reliable boot-up and operation of the AM3874BCYE100?
  To ensure reliable boot-up and operation, use a robust power supply, follow the recommended power-on sequence, and implement a reliable boot loader and operating system. Additionally, ensure that the device is properly configured and initialized, and that the clock sources are stable and accurate.
• What are the considerations for PCB design and layout when using the AM3874BCYE100?
  When designing the PCB, consider the device's power distribution, signal integrity, and thermal management. Use a multi-layer PCB, follow Texas Instruments' recommended layout guidelines, and ensure proper decoupling, filtering, and shielding to minimize noise and interference.
