description
The TMS320UC5409 fixed-point, digital signal processor (DSP) (hereafter referred to as the 鈥橴C5409 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
鈥?IEEE Standard 1149.1-1990 Standard-Test-Access Port and Boundary Scan Architecture.
ADVANCE INFORMATION concerns new products in the sampling or
preproduction phase of development. Characteristic data and other
specifications are subject to change without notice.
