TMS320C6711BGFN150

Digital Signal Processor Dsp Overview

The TMS320C6711BGFN150 is a floating-point digital signal processor from the TMS320C67x family, manufactured by Texas Instruments. It operates at a maximum clock frequency of 150 MHz with a core voltage of 1.9 V and I/O voltage of 3.3 V. The device utilizes a 0.18-µm CMOS process and features an advanced VLIW C67x DSP core capable of executing eight 32-bit instructions per cycle. It includes 4 KB L1P program cache, 4 KB L1D data cache, and 64 KB unified L2 memory. The component is housed in a 256-pin Ball Grid Array (BGA) package.

Digital Signal Processor Dsp Feature Summary

• C67x VLIW architecture with eight independent functional units: four ALUs, two multipliers, and two address generators
• Hardware support for IEEE single-precision and double-precision floating-point operations
• Two-level cache-based memory architecture with 64 KB unified L2 RAM/cache
• Enhanced Direct-Memory-Access (EDMA) controller with 16 independent channels

Digital Signal Processor Dsp Applications

• Real-time image processing systems
• V.34 analog modem implementations
• Satellite attitude control subsystems
• Voice Over IP (VoIP) devices

Digital Signal Processor Dsp Procurement Notes

Verify that the ordering suffix GFN corresponds to the 256-pin BGA package and 150 MHz speed grade. Confirm RoHS compliance status as specifications may vary by revision. Ensure the design accounts for the specific 1.9 V core voltage requirement distinct from later C6711C/D variants. Check for moisture sensitivity levels if storage conditions are not controlled.

Digital Signal Processor Dsp Selection Notes

Select this model when a 150 MHz floating-point performance level is required with a 256-pin footprint. Note that it uses a 0.18-µm process and 1.9 V core voltage, differing from the 0.13-µm/1.26 V C6711C/D series. It is pin-compatible with the fixed-point TMS320C6211/C6211B for mixed-signal system designs requiring architectural flexibility.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C67x floating-point DSP family, which also includes the C6711, C6711C, and C6711D. The 'B' designation indicates a specific silicon revision or speed bin within the original C6711 generation. The GFN suffix specifically denotes the 256-pin BGA package type, distinguishing it from the 272-pin GDP package used in higher-speed variants.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6711BGNA100 is a lower-speed variant (100 MHz) of the same package and core. For direct replacement, verify that the 150 MHz clock rate does not exceed the timing constraints of the external memory interface. The TMS320C6711C/D series offers higher speeds but requires different power supply voltages (1.26 V) and PCB layout adjustments.
