Overview
The TMS320LC203PZA is a digital signal processor (DSP) from Texas Instruments, part of the TMS320C2xx generation. This DSP is based on the T320C2xLP core CPU, which is optimized for high speed, small size, and low power consumption. The TMS320LC203PZA combines strong performance and great flexibility, making it ideal for demanding applications in signal processing and control.
The device features a 16-bit fixed-point DSP architecture with six internal buses, enhancing parallelism and performance. It also includes a 32-bit ALU/accumulator and a 16 × 16-bit single-cycle multiplier. The DSP is source code compatible with the TMS320C25 and upwardly code-compatible with TMS320C5x devices, ensuring code investment is preserved.
