TMS320C50PGE80

Digital Signal Processor Dsp Overview

The TMS320C50PGE80 is a 16-bit digital signal processor from the Texas Instruments TMS320C5x family, fabricated using static CMOS technology. It features a single-cycle 16 × 16-bit multiply/add capability and executes instructions in 50 ns for 5-V operation. The device provides up to 224K × 16-bit addressable external memory space and includes on-chip program ROM (up to 32K words) and RAM (up to 9K words). It incorporates full-duplex synchronous serial ports, a buffered serial port, and a host port interface. The PGE suffix indicates a 144-pin thin quad flat package.

Digital Signal Processor Dsp Feature Summary

• Single-cycle 16 × 16-bit multiply/add execution
• 50-ns instruction cycle time at 5 V supply voltage
• On-chip memory: up to 32K × 16-bit ROM and 9K × 16-bit SARAM
• Integrated Host Port Interface (HPI) and Buffered Serial Port (BSP)

Digital Signal Processor Dsp Applications

• Coder/decoder interfaces via full-duplex synchronous serial port
• Time-division-multiplexed (TDM) serial communication
• Host-based control systems utilizing the HPI

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '80' against the official datasheet specifications, as standard listings typically denote '50'. Confirm that the PGE package corresponds to the 144-pin thin quad flat package. Ensure the component matches the 5-V operation requirements defined for the C50 series.

Digital Signal Processor Dsp Selection Notes

Select this device for applications requiring a 16-bit fixed-point DSP with a 50-ns cycle time. The C50 variant offers higher on-chip memory capacity compared to the C51 or C52 models. Verify compatibility with 5-V logic levels and ensure the 144-pin PGE package fits the target PCB layout constraints.

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 C50 model specifically provides a balance of processing speed and memory resources within the 5-V operating family.

Digital Signal Processor Dsp Replacement Considerations

The TMS320LC50 serves as a low-voltage (3.3 V) alternative within the same architecture. Other C5x variants like the C51 or C53 offer different memory configurations but share similar core performance characteristics.
