The recommended power-on sequence is to apply VDD (1.8V to 2.2V) first, followed by VDDA (1.8V to 2.2V), and then VDDS (1.2V to 1.4V) last. This ensures proper power-up of the device.
The TMS320UC5402GGU-80 has multiple clock sources, including an internal oscillator, external crystal oscillator, and PLL. The clock sources can be configured using the Clock Enable Register (CLKEN) and the Clock Source Select Register (CLKSRC). Refer to the device's user guide for specific configuration details.
The maximum operating temperature range for the TMS320UC5402GGU-80 is -40°C to 85°C. However, it's recommended to operate the device within the industrial temperature range of -40°C to 70°C for optimal performance and reliability.
The TMS320UC5402GGU-80 has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WDTCTL). The watchdog timer can be used to reset the device in case of a software fault or hang-up.
The maximum current draw for the TMS320UC5402GGU-80 depends on the operating frequency and voltage. At 80 MHz and 1.8V, the maximum current draw is approximately 250 mA. However, this value can vary depending on the specific application and usage.
