TMS320VC5509APGE

Digital Signal Processor Dsp Overview

The TMS320VC5509APGE is a fixed-point digital signal processor from Texas Instruments, based on the C55x DSP architecture. It operates at a maximum clock frequency of 200 MHz with an instruction cycle time of 5 nanoseconds. The device features a 32-bit data bus and delivers up to 400 MIPS performance. Internal memory includes 128 KB of RAM (64 KB DARAM and 64 KB SARAM) and 64 KB of ROM. It utilizes a modified Harvard architecture with separate program and data buses for high throughput.

Digital Signal Processor Dsp Feature Summary

• C55x DSP core with 5-level enhanced pipeline
• Dual multipliers supporting 400 MMACS
• 128 KB internal RAM and 64 KB internal ROM
• 144-pin LQFP surface-mount package

Digital Signal Processor Dsp Applications

• Portable palmprint recognition systems
• MP3 real-time decoding

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized distributors or TI direct channels. Check RoHS compliance status and moisture sensitivity levels before assembly. Confirm lead frame material and marking codes match official datasheet specifications. Ensure storage conditions adhere to JESD22-A114 standards to prevent damage prior to soldering.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring low-power fixed-point processing at 200 MHz. Compare against other C55x variants based on pin count and memory size requirements. Ensure the design supports the required 1.6 V and 3.3 V power domains. Verify that the 144-pin LQFP package fits the PCB footprint constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5509A family within the C5000 series. It shares the same CPU core as variants like TMS320VC5509AZAYR but differs in package type and pin configuration. The APGE suffix denotes the 144-pin LQFP package variant optimized for surface mount technology.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other TMS320VC5509A variants such as TMS320VC5509AZAYR or TMS320VC5509AGBBR, provided the pinout and package dimensions are compatible with the existing board layout.
