VC55GPSGHH

Overview

The VC55GPSGHH is a fixed-point digital signal processor from the TMS320VC55xx DSP family, manufactured by Texas Instruments. It features a 16-bit architecture with a maximum clock frequency of 50 MHz and supports multiple internal bus architectures for efficient data throughput. The device includes boundary scan capabilities for testing and verification. It operates within a supply voltage range that typically includes 1.2V, 1.35V, and 1.8V options, designed for low-power applications. The component is housed in a 179-pin LFBGA package, providing extensive I/O connectivity for complex embedded systems.

Part Context

The VC55GPSGHH belongs to the TMS320VC55xx series, a widely used family of low-power, high-performance DSPs. This specific part number denotes a commercial or industrial grade variant with specific pinout and thermal characteristics defined by the LFBGA-179 package. It is distinct from other variants in the series by its packaging and specific speed binning, serving as a core processing unit in battery-operated devices.

Replacement Considerations

Direct replacements should be sought within the TMS320VC55xx family, such as the TMS320VC5503 or similar LFBGA-179 packaged parts. Verify pin compatibility and software instruction set alignment before substitution. Note that suffixes may indicate temperature ranges or lead-free status; ensure the replacement matches the required environmental specifications.
