FAQ

What is the maximum operating frequency of the TMS320C6413GTS500?

The TMS320C6413GTS500 operates at a guaranteed maximum frequency of 500 MHz, delivering 4000 million instructions per second (MIPS). This rating is validated across the full industrial temperature range (–40°C to 105°C case temperature) and specified under recommended supply conditions: CVDD = 1.2 V ± 3%, DVDD = 3.3 V ± 5%. The device achieves this performance using its C64x+ VLIW core with VelociTI.2™ enhancements and on-chip PLL.

Does the TMS320C6413GTS500 support booting from external flash memory?

Yes, the TMS320C6413GTS500 supports booting from external flash via its EMIFA 8-bit ROM boot mode, enabled by setting AEA[22:21] = 11 at reset. In this mode, the device fetches the boot vector and initial code from address 0x00000000 on the EMIFA data bus, allowing direct execution from parallel NOR flash or SPI flash connected through a glueless interface. Configuration details are documented in Section 4.12 of SPRS247F.

How much on-chip memory does the TMS320C6413GTS500 provide, and how is it allocated?

The TMS320C6413GTS500 integrates 1024 KB of on-chip L2 memory, fully configurable as SRAM or cache, plus 64 KB L1P program cache and 64 KB L1D data cache. Unlike earlier C64x devices, the L2 block is unified and software-managed-no fixed split between instruction and data space. This flexibility allows developers to allocate all 1024 KB as scratch RAM for audio buffers or partition it for mixed code/data use without hardware constraints.

Can the TMS320C6413GTS500 interface directly with SDRAM, and what are the timing requirements?

Yes, the TMS320C6413GTS500's EMIFA includes a dedicated SDRAM controller supporting 16-/32-bit x 1M/2M/4M/8M devices with programmable CAS latency (2 or 3), burst length (1/2/4/8), and refresh intervals. Key timing parameters include tRC ≥ 60 ns, tRCD ≥ 20 ns, and tRP ≥ 20 ns at 500-MHz CPU clock. All SDRAM timing registers (SDRAMCR, SDCR, etc.) are memory-mapped at 0x01800000 and configurable in real time via the DSP's EDMA or CPU.

What peripheral interfaces are available on the TMS320C6413GTS500 for audio applications?

The TMS320C6413GTS500 features two independent Multichannel Audio Serial Ports (McASP0 and McASP1), each supporting 16 transmit and 16 receive channels, TDM, I²S, and custom frame formats. Each McASP includes dedicated clock generators, serializers, and DMA-aware data FIFOs. Additional audio-relevant peripherals include I²C (for CODEC configuration), GPIO (for mute/reset control), and EMIFA (for external audio buffer memory), making the TMS320C6413GTS500 a self-contained audio processing node.
