OMAPL138BZCEA3E datasheet by Texas Instruments

OMAPL138BZCEA3E Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for OMAPL138BZCEA3E?
  The recommended power-up sequence is to power up the core voltage (VDD) first, followed by the I/O voltage (VDDA). This ensures that the internal voltage regulators are properly enabled before the I/O pins are powered up.
• How do I configure the clock sources for the OMAPL138BZCEA3E?
  The OMAPL138BZCEA3E has multiple clock sources, including an internal oscillator, an external crystal oscillator, and an external clock source. The clock sources can be configured using the clock control module (CCM) registers. Refer to the OMAPL138BZCEA3E TRM (Technical Reference Manual) for detailed information on clock configuration.
• What is the maximum operating frequency of the OMAPL138BZCEA3E?
  The maximum operating frequency of the OMAPL138BZCEA3E is 456 MHz. However, the actual operating frequency may be limited by the specific application, power consumption, and thermal considerations.
• How do I implement a watchdog timer on the OMAPL138BZCEA3E?
  The OMAPL138BZCEA3E has a built-in watchdog timer module that can be configured to generate a reset signal if the system fails to respond within a specified time period. The watchdog timer can be enabled and configured using the watchdog timer module (WT) registers.
• What is the purpose of the EMIF (External Memory Interface) on the OMAPL138BZCEA3E?
  The EMIF is used to interface with external memory devices such as SDRAM, DDR2, and asynchronous memory. The EMIF provides a flexible interface for accessing external memory, allowing the OMAPL138BZCEA3E to access large amounts of memory for data storage and processing.
