Digital Signal Processors (DSP) are used to process signals in a variety of applications including audio, video, telecommunications and medical devices. The TMS320C25FNA is a 16/32-bit fixed-point digital signal processor that is also useful for controlling system operations, such as gauging and controlling voltage levels and digital signals. The C25FNA provides the flexibility, speed and power to efficiently process multiple signals in an embedded system with a minimal number of circuitry components.

The TMS320C25FNA is designed for use in applications that require intensive signal processing, such as graphic processing, audio and video streaming, or PC communications. It offers up to 4 Kbytes of program memory, up to 512 bytes of on-chip RAM, and up to 2 Kbytes or 4 Kbytes of data memory. The C25FNA is suited for numerous real-time applications such as motor speed and position control, USB applications, wireless communications, and consumer audio systems. The processor’s fast vector processing mode provides fast and efficient handling of real-time digital audio signals.

The C25FNA has many modules and peripheral sets that support a wide range of applications. The device includes an arithmetic logic unit (ALU), dual accumulator, parallel multiplier/accumulator, monitor and debug system, general-purpose I/O port module, on-chip clock oscillator and audio filtering modules. The C25FNA’s power-saving features, such as programmable clock divider and voltage scaling, can reduce the power consumption of a system. The processor supports multiple instruction sets and can be programmed in either assembly or C language.

The C25FNA also offers an interrupt controller and programmable cycle rate counter/timer (TCR) to assist in scheduling real-time system functions and other tasks. The controller can be used in conjunction with a real-time operating system (RTOS) to coordinate the operation of the entire system. The processor also includes an on-chip emulation controller to help debug programs written in C language. Debugging capabilities are available through an integrated development environment (IDE) such as Code Composer Studio.

The TMS320C25FNA processor is ideal for applications that require high-performance, low-power digital signal processing. The processor offers a low-cost, flexible solution for embedded systems that require real-time performance. The C25FNA provides a rich set of features, making it well-suited for applications such as motor control, image processing, audio and video streaming, telecommunications, and data acquisition.
