VC55GPSPGE

Overview

The Texas Instruments VC55GPSPGE is a fixed-point digital signal processor belonging to the TMS320VC5509A series. It operates at a clock frequency of 200 MHz and features 256 KB of on-chip RAM. The device is housed in a 144-pin LQFP package with surface-mount installation. It supports an operating temperature range from -40°C to +85°C. This component is classified as an embedded processor designed for low-power applications within the C55x DSP family.

Feature Summary

• Fixed-point digital signal processing architecture optimized for low power consumption
• Integrated high-speed memory subsystem with on-chip RAM for efficient data handling
• Supports multimedia controller functions within the TMS320VC5509A series

Applications

• Low-power audio processing systems
• Embedded control applications requiring fixed-point arithmetic
• Multimedia signal processing tasks

Procurement Notes

Verify the specific ordering suffix PGE against the manufacturer's current datasheet to confirm pinout, package dimensions, and thermal characteristics. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm moisture sensitivity level requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this component when a 200 MHz fixed-point DSP with integrated memory is required for space-constrained designs. The 144-pin LQFP package offers a balance between pin count and board area. Consider the -40°C to +85°C industrial temperature range for environmental suitability. Evaluate the 256 KB RAM capacity against application memory demands before finalizing the design.

Part Context

This part belongs to the TMS320VC5509A series, which extends the capabilities of the earlier VC5509 architecture. It is designed for applications needing efficient digital signal processing with reduced power consumption. The series is commonly used in portable electronics and industrial control systems where performance per watt is critical.

Replacement Considerations

Public confirmed substitutes include VC55GPSZHH and VC55GPSGHH. Verify package type differences, such as BGA versus LQFP, and ensure functional equivalence in the target application before substitution.
