Product details
Overview
TMS320C6701GJC150 from Texas Instruments is a high-performance floating-point digital signal processor (DSP) based on the VelociTI VLIW architecture, delivering 1 GFLOPS at 150 MHz with 8 instructions/cycle, 1M-bit on-chip SRAM (512K program/cache + 512K dual-access data), and 32-bit EMIF for SDRAM/SBSRAM interfacing - deployed in multichannel audio processing, radar baseband, and real-time communications infrastructure.
For engineers reviewing the TMS320C6701GJC150 datasheet, TMS320C6701GJC150 pinout, TMS320C6701GJC150 application, or TMS320C6701GJC150 equivalent, key selection criteria include IEEE 754 single/double-precision hardware support, 352-pin GJC BGA package compatibility, 1.8-V core/3.3-V I/O voltage configuration, and pin-for-pin alignment with TMS320C6201 fixed-point DSPs.
Technical Context
The TMS320C6701GJC150 implements a dual-path VelociTI CPU with two register files (A/B, 16×32-bit each) and eight functional units: four ALUs (two floating-/fixed-point, two fixed-point), two multipliers (floating-/fixed-point), and two load/store units (.D1/.D2). It executes up to eight 32-bit instructions per cycle via variable-length execute packets derived from 256-bit fetch packets.
Its memory subsystem includes 64KB configurable program memory (cache/mapped), two 32KB data RAM blocks with 50/50 bank split, and a glueless 32-bit EMIF supporting synchronous (SDRAM, SBSRAM) and asynchronous (SRAM, EPROM) memories across 52MB address space. The device integrates two McBSPs (AC97-, SPI-, T1/E1-compatible), 16-bit HPI, four-channel DMA, dual 32-bit timers, and IEEE-1149.1 JTAG boundary-scan.

FAQ
What is the core supply voltage requirement for the TMS320C6701GJC150?
The TMS320C6701GJC150 requires a 1.8-V core supply (CVDD) and 3.3-V I/O supply (DVDD). This dual-rail configuration is fixed for the -150 speed grade and must be implemented with separate low-noise regulators and proper decoupling per TI's PCB layout guidelines to ensure signal integrity and timing margin compliance.
Does the TMS320C6701GJC150 support IEEE 754 double-precision arithmetic in hardware?
Yes, the TMS320C6701GJC150 provides full hardware acceleration for IEEE 754 single- and double-precision floating-point operations via six of its eight functional units (.L1, .M1, .D1, .D2, .M2, .L2). This eliminates software emulation overhead and ensures deterministic execution time for numerically intensive algorithms like QR decomposition or Kalman filtering.
Is the TMS320C6701GJC150 pin-compatible with any fixed-point DSPs?
Yes, the TMS320C6701GJC150 is explicitly pin-compatible with the TMS320C6201 fixed-point DSP. This allows hardware reuse across floating-point and fixed-point variants in development platforms, though software must be recompiled due to architectural differences in instruction set and register file behavior.
What memory interfaces does the TMS320C6701GJC150 EMIF support without external logic?
The TMS320C6701GJC150 EMIF supports glueless interfacing to SDRAM, SBSRAM, SRAM, and EPROM. Its dedicated control signals - including SDRAS/SDCAS/SDWE for SDRAM, SSADS/SSOE/SSWE for SBSRAM, and ARE/AOE/AWE for asynchronous memories - eliminate need for address latches or PAL/FPGA glue logic in standard memory configurations.
How many independent serial ports does the TMS320C6701GJC150 integrate?
The TMS320C6701GJC150 integrates two multichannel buffered serial ports (McBSP0 and McBSP1), each supporting up to 256 time-division multiplexed channels, AC97 audio codec timing, SPI master/slave modes, and T1/E1 framing - enabling direct connection to voice codecs, RF transceivers, and digital subscriber line (DSL) PHYs without external interface ICs.
