说明

The TMS320UC5402 fixed-point, digital signal processor (DSP) (hereafter referred to as the UC5402 unless otherwise specified) is ideal for low-power, high-performance applications. This processor offers very low power consumption and the flexibility to support various system voltage configurations. The wide range of I/O voltage enables it to operate with a single 1.8-V power supply or with dual power supplies for mixed voltage systems. This feature eliminates the need for external level-shifting and reduces power consumption in emerging sub-3V systems.

Texas Instrument (TI) DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage.
