TMS320C52PZ

Digital Signal Processor Dsp Overview

The TMS320C52PZ is a 16-bit fixed-point digital signal processor from the Texas Instruments TMS320C5x family, housed in a 100-pin Thin Quad Flat Package (PZ suffix). It operates on a 5-V supply and supports single-cycle instruction execution times of 50 ns, 35 ns, 25 ns, and 20 ns. The device features an advanced Harvard architecture with up to 224K × 16-bit addressable external memory space. On-chip resources include 544 words of DARAM, 512 words of SARAM, and 4K × 16-bit of single-access Program ROM. It integrates a full-duplex synchronous serial port, a host port interface, and IEEE 1149.1 JTAG test access.

Digital Signal Processor Dsp Feature Summary

• 16-bit C5x CPU with single-cycle 16 × 16-bit multiply/add capability
• Variable cycle times: 50/35/25/20 ns at 5 V operation
• On-chip memory: 544 DARAM, 512 SARAM, 4K ROM
• Integrated Host Port Interface (HPI) for parallel host communication

Digital Signal Processor Dsp Applications

• Digital control systems requiring parallel host interface
• Audio and voice processing applications
• Modems and telecommunications equipment
• Industrial motor control and automation

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -50, -35, -25, -20) required for the target clock frequency, as the base model number does not specify execution time. Confirm that the 5-V power supply requirement aligns with the system design, as low-power LC52 variants operate at 3.3 V. Ensure the 100-pin PZ package footprint matches the PCB layout constraints.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C52PZ when a Host Port Interface is necessary for direct parallel connection to a microprocessor or host system. Choose this part over the LC52 variant if the application requires 5-V I/O levels rather than 3.3-V. Consider the 4K on-chip ROM capacity for boot code storage; larger memory requirements may necessitate the TMS320C53 or C57 models.

Digital Signal Processor Dsp Part Context

The TMS320C52PZ belongs to the TMS320C5x generation of DSPs, which are upward-compatible with source code from earlier C1x and C2x devices. This family utilizes high-performance static CMOS technology to minimize power consumption while maximizing radiation tolerance. The PZ suffix specifically denotes the 100-pin Thin Quad Flat Package option available for this device series.

Digital Signal Processor Dsp Replacement Considerations

For 3.3-V operation, consider the TMS320LC52PZ. For increased on-chip memory or additional serial ports, evaluate the TMS320C53S or TMS320C51. Direct pin-compatible replacements within the same package are limited to other C5x devices with matching pinouts.
