device compatibility

The TMS320C6211/C6211B and C6711/C6711B devices are pin-compatible and have the same peripheral set;

thus, making new system designs easier and providing faster time to market. The following list summarizes the

device characteristic differences among the C6211, C6211B, C6711, C6711B, C6711C, and C6711D devices:

D The C6211 and C6211B devices have a fixed-point C62x CPU, while the C6711, C6711B, C6711C, and

C6711D devices have a floating-point C67x CPU.

D The C6211/C6211B device runs at -167 and -150 MHz clock speeds (with a C6211BGFNA extended

temperature device that also runs at -150 MHz), while the C6711/C6711B device runs at -150 and -100 MHz

(with a C6711BGFNA extended temperature device that also runs at -100 MHz) and the C6711C/C6711D

device runs at -200 clock speed (with a C6711CGDPA and C6711DGDPA extended temperature devices

that also run at -167 MHz).

D The C6211/C6211B, C6711-100, and C6711B devices have a core voltage of 1.8 V, the C6711-150 device

core voltage is 1.9 V, and the C6711C and C6711D devices operate with a core voltage of 1.20† V.

D There are several enhancements and features that are only available on the C6711C/C6711D device, such

as: the CLKOUT3 signal, a software programmable PLL and PLL Controller, and a GPIO peripheral module.

The C6711D device also has 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.

device, see the Migrating from TMS320C6211B/6711B to TMS320C6711C application report (literature number

SPRA837).

For a more detailed discussion on the similarities/differences between the C6211 and C6711 devices, see the

How to Begin Development Today with the TMS320C6211 DSP

and How to Begin Development with the

TMS320C6711 DSP

application reports (literature number SPRA474 and SPRA522, respectively).

† This value is compatible with existing 1.26V designs.
