TMS320C52PJ57

Digital Signal Processor Dsp Overview

The TMS320C52PJ57 is a digital signal processor from the Texas Instruments TMS320C5x family, fabricated using high-performance static CMOS technology. It features a powerful 16-bit CPU capable of executing up to 50 million instructions per second (MIPS). The device supports single-cycle instruction execution times of 50 ns, 35 ns, and 25 ns for 5-V operation, and 50 ns, 40 ns, and 25 ns for 3-V operation. It includes 544 words of dual-access on-chip RAM (DARAM), 512 words of single-access SARAM, and 4K words of single-access on-chip ROM. The processor provides a 224K x 16-bit addressable external memory space and integrates peripherals such as a full-duplex synchronous serial port, a buffered serial port, and a host port interface.

Digital Signal Processor Dsp Feature Summary

• Executes up to 50 MIPS with single-cycle 16 × 16-bit multiply/add operations
• Includes 4K × 16-bit on-chip program ROM and 544-word DARAM
• Supports multiple clocking options via Phase-Locked Loop (PLL) with multipliers up to ×9
• Integrates IEEE Standard 1149.1 Test-Access Port (JTAG) for boundary scan and emulation

Digital Signal Processor Dsp Applications

• Digital cellular modem implementation
• Coder/decoder (CODEC) interfaces
• Time-division-multiplexed (TDM) serial communication systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix PJ57 against the manufacturer's current documentation to confirm pinout compatibility and electrical specifications. Confirm that the 5-V operation requirements align with the system design, as the C5x family also offers 3-V LC variants. Check for end-of-life status or alternative recommendations in the latest TI product selection guide before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C52PJ57 when 5-V operation is required alongside 4K words of on-chip ROM. The PJ suffix indicates a 100-pin Quad Flat Package (QFP). Ensure the application utilizes the available serial ports, noting that this specific model lacks the Time-Division-Multiplexed (TDM) serial port found in other C5x variants like the C51. Verify power supply constraints, as the device draws 47 mA at 5 V and 40 MHz.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C5x generation of DSPs, which are upward-compatible with source code from earlier C1x and C2x devices. The C52 variant specifically distinguishes itself by offering 4K words of on-chip ROM without the TDM serial port, making it suitable for applications requiring moderate on-chip storage but standard serial communication.
