STM32MP153AAC3 - STMicroelectronics

STM32MP153AAC3 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STM32MP153AAC3?
  The STM32MP153AAC3 can operate from -40°C to 125°C (junction temperature), but the recommended operating temperature range is -20°C to 85°C for optimal performance and reliability.
• How do I configure the clock tree for the STM32MP153AAC3?
  The clock tree configuration for the STM32MP153AAC3 involves setting up the clock sources, PLLs, and clock dividers using the Clock Control Register (CCR) and the Power and Clock Controller (PCC). Refer to the STM32MP1 Series Reference Manual and the STM32CubeMX tool for guidance.
• What is the maximum frequency for the Cortex-A7 and Cortex-M4 cores?
  The maximum frequency for the Cortex-A7 core is 650 MHz, and for the Cortex-M4 core is 209 MHz. However, the actual frequency may vary depending on the system configuration, voltage, and temperature.
• How do I use the TrustZone security features on the STM32MP153AAC3?
  The STM32MP153AAC3 has a TrustZone-enabled Cortex-A7 core, which allows for secure boot, secure firmware updates, and secure data storage. Use the Arm TrustZone documentation and the STM32MP1 Series Reference Manual to learn more about implementing TrustZone security features.
• What is the difference between the STM32MP153AAC3 and the STM32MP153DAC3?
  The main difference between the STM32MP153AAC3 and the STM32MP153DAC3 is the package type. The STM32MP153AAC3 is available in a 354-ball LFBGA package, while the STM32MP153DAC3 is available in a 448-ball TFBGA package. The DAC3 package has more pins, which allows for more peripherals and interfaces to be connected.
