TMS320C50PGE

Digital Signal Processor Dsp Overview

The TMS320C50PGE is a 16-bit digital signal processor from the Texas Instruments TMS320C5x family, housed in a 144-pin Thin Quad Flat Package (PGE suffix). It operates on a 5-V supply and achieves single-cycle instruction execution times of 50 ns, 35 ns, or 25 ns. The device features a powerful 16-bit CPU with a single-cycle 16 × 16-bit multiply/add capability. Memory resources include 544 words of DARAM, 512 words of SARAM, 9K words of ROM, and 2K words of boot ROM. It supports a maximum addressable external memory space of 224K × 16 bits.

Digital Signal Processor Dsp Feature Summary

• Executes up to 50 million instructions per second (MIPS) using static CMOS technology.
• Includes full-duplex synchronous serial port, time-division-multiplexed (TDM) serial port, and buffered serial port.
• Supports multiple phase-locked loop (PLL) clocking options for flexible system timing.
• Integrates on-chip scan-based emulation logic and IEEE Standard 1149.1 test-access port (JTAG).

Digital Signal Processor Dsp Applications

• Coder/decoder interface applications via full-duplex synchronous serial port.
• Control operations utilizing the integrated on-chip timer.
• Systems requiring efficient program space usage through repeat instructions.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix required for the target clock frequency, as the base model designation covers multiple execution times. Confirm that the 144-pin PGE package aligns with the PCB footprint design. Ensure power supply decoupling meets the requirements for the 5-V operation mode specified in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component when a 5-V operating voltage is mandatory, as the LC50 variant is designed for 3.3 V. Compare memory configurations against application needs; the C50 provides 9K words of ROM compared to other variants like the C51 which offers 8K words. Consider the pin count and peripheral availability, such as the host port interface, if parallel communication with a host system is required.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C5x generation of DSPs, which are upward-compatible with source code from earlier TMS320C1x and TMS320C2x families. The architecture is based on the TMS320C25 but utilizes advanced static CMOS processing for improved performance and lower power dissipation compared to previous generations.

Digital Signal Processor Dsp Replacement Considerations

The TMS320LC50 serves as a low-power alternative operating at 3.3 V. For different memory capacities within the same package, consider the TMS320C51 or TMS320C53. Verify that any replacement maintains compatibility with the 144-pin PGE form factor and existing software libraries.
