TMS320C203PZ57

Digital Signal Processor Dsp Overview

The TMS320C203PZ57 is a 16-bit fixed-point digital signal processor based on the T320C2xLP core, housed in a 100-pin LQFP package. It features a modified Harvard architecture with six internal buses for high parallelism and a 32-bit ALU/accumulator. The device includes a 16 × 16-bit single-cycle multiplier and supports up to 40 MIPS performance at 5 V (25 ns cycle time). On-chip memory consists of 544 words of dual-access data RAM. It offers a 224K × 16-bit external address space, a PLL, a 20-bit timer, UART, and synchronous serial port.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized Texas Instruments channels or certified distributors. Confirm RoHS compliance status and check for moisture sensitivity handling requirements prior to assembly. Ensure the specific PZ suffix corresponds to the required 100-pin LQFP package configuration for your PCB layout.

Digital Signal Processor Dsp Selection Notes

Select this model when code compatibility with legacy TMS320C25 or upward compatibility with C5x devices is required. Choose the TMS320C203PZ57 over the ’C209 variant if on-chip ROM is not needed but external memory flexibility is prioritized. Ensure the design supports the necessary 5 V power supply and external clock oscillator circuitry for optimal operation.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C2xx generation of DSPs, which are designed for signal processing and control applications. It shares the same core architecture as the TMS320C209 and TMS320LC203 but differs in memory configuration and peripheral availability. The PZ57 designation indicates the 100-pin Thin Quad Flat Package variant.

Digital Signal Processor Dsp Replacement Considerations

The TMS320F206 is pin-compatible with the TMS320C203. For upgrades within the family, consider the TMS320C209 for integrated ROM or the TMS320LC203 for lower voltage operation.
