TMS320C5420PGEA200

Digital Signal Processor Dsp Overview

The TMS320C5420PGEA200 is a fixed-point digital signal processor featuring two independent C54x subsystems. It delivers up to 200-MIPS performance with a 16-bit data bus and 40-bit arithmetic logic unit. The device includes 192K × 16 dual- and single-access on-chip RAM, operating at 1.8 V core and 3.3 V I/O supplies. It supports 160 MHz clock speeds in industrial temperature ranges (-40°C to 100°C) and is housed in a 144-pin LQFP package.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture with two independent C54x subsystems
• Up to 200 MIPS processing speed with 10-ns instruction execution
• 192K × 16 on-chip RAM for program and data storage
• Six Multichannel Buffered Serial Ports (McBSPs) and 12 DMA channels

Digital Signal Processor Dsp Applications

• High-performance audio processing systems
• Modems and telecommunications equipment
• Industrial control applications requiring dual-core DSPs
• Voice recognition and speech synthesis hardware

Digital Signal Processor Dsp Procurement Notes

Verify the 'A' suffix confirms the industrial temperature range (-40°C to 100°C). Confirm the 'PGE' designation matches the required 144-pin Low-Profile Quad Flatpack package. Ensure the '200' rating aligns with the specific clock frequency requirements of the design.

Digital Signal Processor Dsp Selection Notes

Select this component when dual-core parallel processing is necessary. The 1.8V/3.3V power scheme requires appropriate voltage regulators. Verify that the 144-pin LQFP footprint fits the PCB layout constraints compared to the BGA alternative.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5420 family, which includes commercial variants like the TMS320VC5420PGE200. The primary distinction is the extended temperature range provided by the 'A' suffix in the TMS320C5420PGEA200 model.
