TMS320C25GBA Description

The TMS320C25GBA from Texas Instruments is a fixed-point digital signal processor (DSP) belonging to the TMS320C2x series. Packaged in a 68-pin CPGA (Ceramic Pin Grid Array) and designed for through-hole mounting, this DSP delivers robust performance with a 50MHz clock rate, making it suitable for real-time signal processing tasks. It features 8kB of on-chip ROM for program storage and 1kB of on-chip RAM for data operations, ensuring efficient execution of algorithms. Operating at 5V core and I/O voltage, it integrates a serial port interface for streamlined communication. Though classified as "Not For New Designs", it remains relevant in legacy systems requiring high reliability.
