TMS320UC5409 pdf datasheet

The TMS320UC5409 fixed-point, digital signal processor (DSP) (hereafter referred to as the 'UC5409 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.

The TMS320UC5409 fixed-point, digital signal processor (DSP) (hereafter referred to as the 'UC5409 unless otherwise specified) is based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction set.
