TMS320VC5510GGW1

Digital Signal Processor Dsp Overview

The TMS320VC5510GGW1 is a fixed-point digital signal processor based on the TMS320C55x architecture, designed for high performance and low power consumption. It features a CPU core with two MAC units capable of 17-bit x 17-bit multiplication in a single cycle, supporting up to 400 MMACS. The device operates at clock rates of 160 MHz or 200 MHz, corresponding to instruction cycle times of 6.25 ns or 5 ns. It includes 160K x 16-bit on-chip RAM (64K DARAM and 96K SARAM), 16K x 16-bit on-chip ROM, and a 24K-byte instruction cache. The processor utilizes a 32-bit external memory interface and is housed in a 240-terminal MicroStar BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix associated with the GGW package. The datasheet indicates that the '1' in the model number typically denotes a 160-MHz maximum clock rate, while other suffixes may indicate 200-MHz operation. Confirm the operating voltage requirements: 3.3-V I/O supply and 1.6-V core supply. Ensure compatibility with the 240-terminal MicroStar BGA footprint during PCB design.

Digital Signal Processor Dsp Selection Notes

Select this component when a fixed-point C55x DSP with integrated instruction cache and significant on-chip memory is required. The GGW suffix specifies the 240-terminal MicroStar BGA package. Compare against the ZGW suffix if an alternative BGA package form factor is needed. Consider the 160-MHz vs. 200-MHz speed grades depending on real-time processing constraints and power dissipation limits.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5510/5510A family within the broader TMS320C55x series. The C55x generation focuses on parallelism to achieve high performance at low voltages. The VC5510 variant specifically integrates the instruction cache and larger memory blocks compared to earlier C55x predecessors, making it suitable for complex algorithms without extensive external memory access.
