The C6712 device runs at -100 MHz clock speed and the C6712C/C6712D device runs at -150 MHz clock speed.

DThe C6211/C6211B, C6711-100, C6711B and C6712 devices have a core voltage of 1.8 V, the C6711-150 device has a core voltage is 1.9 V, and the C6711C/C6711D and C6712C/C6712D devices operate with a core voltage of 1.20† V.

DThere are several enhancements and features that are only available on the C6711C/C6711D and C6712C/C6712D devices, such as: the CLKOUT3 signal, a software-programmable PLL and PLL Controller, and a GPIO peripheral module. The C6711D and C6712D devices also have additional enhancements such as: EMIF Big Endian mode correctness EMIFBE and the L1D requestor priority to L2 bit [“P” bit] in the cache configuration (CCFG) register. C6712D supports Big Endian mode.

DThe C6712/C6712C/C6712D is the lowest-cost entry in the TMS320C6000platform.
