The recommended power-on sequence is to power up the VDDS (digital core) first, followed by VDDS_DDR (DDR memory), and then VDDS_WIFI (Wi-Fi and analog circuits). This ensures proper initialization and prevents damage to the device.
To optimize Wi-Fi performance, ensure that the PCB layout follows the recommended guidelines, use a good quality antenna, and optimize the Wi-Fi settings in the software. Additionally, consider using the TI-provided Wi-Fi optimization tools and guidelines.
The maximum operating temperature range for the CC3235SM2RGKR is -40°C to 85°C. However, it's recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance and reliability.
TI provides a secure boot and firmware update solution through the TI Secure Boot and Firmware Update (SBU) tool. This tool enables secure boot, firmware encryption, and secure firmware updates. Consult the TI documentation and software development kits (SDKs) for more information.
When designing a PCB with the CC3235SM2RGKR, consider the following: use a 4-layer PCB, follow the recommended PCB layout guidelines, ensure proper decoupling and power supply filtering, and use a good quality crystal oscillator. Consult the TI documentation and PCB design guidelines for more information.
