TMS320C6701GJCA120

Digital Signal Processor Dsp Overview

The TMS320C6701GJCA120 is a floating-point digital signal processor from the Texas Instruments C67x family, operating at a maximum clock frequency of 120 MHz. It utilizes a VelociTI VLIW architecture with eight independent functional units: four floating-point/integer ALUs, two integer ALUs, and two multipliers. The device delivers 1 GFLOPS performance and 334 MMACS throughput. It features 512 Kbit of on-chip SRAM configured as program/data memory, a 32-bit external memory interface (EMIF), two McBSPs, two timers, and an HPI. The core operates at 1.8V, while I/O supports 3.3V.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix 'A120' corresponds to the 120 MHz variant in official TI documentation. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check current lifecycle status as older C6701 variants may be obsolete or subject to last-time buys.

Digital Signal Processor Dsp Selection Notes

Select this model when a 120 MHz clock rate is sufficient for the application, offering lower power consumption compared to 150 MHz or 167 MHz variants. Ensure the design accommodates the 1.8V core voltage requirement and provides adequate thermal management for the FCBGA-352 package.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 series, specifically the C67x floating-point subset. It shares architectural similarities with the fixed-point C62x series but adds IEEE single and double-precision floating-point hardware support. It serves as a high-throughput solution for complex mathematical algorithms requiring dynamic range beyond fixed-point capabilities.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same speed grade are limited due to the obsolescence of the original C6701 line. Consider migrating to newer C671x or C674x series devices, noting that these require software adaptation and potentially different peripheral configurations.
