C66x board with no FPGA/CPLD. Is it possible?

Other Parts Discussed in Thread: UCD9090

Hello,

Is it possible to design a low-power C6671 module without FPGA/CPLD? We have a very tight power budget ~10W and are constrained in space.

To my best knowledge in the EVM FPGA firmware implements power sequences, PLL workaround, button/LED control and AMC-related stuff. PLL is now fixed (isn't it) and we don't need neither buttons/LEDs nor AMC. I'm not sure if is it possible to implement power-up/down sequences without external components. If the answer is "no", is an FPGA/CPLD the best solution, or we can it better (using a uC, any intelligent power controllers etc?).

We like FPGAs and the idea is not to avoid FPGA per se but to optimize for power and space.

Thanks,

Dmitry

Hi Dmitry,

The EVM was designed to be as flexible a platform as possible. The FPGA allows us to a greater flexibility to handle changes if necessary. An FPGA is not required for most customer designs. The main function of the FPGA is the sequencing of the power supplies. This can be handled by a much smaller logic device or by a power sequencer such as the UCD9090. The programming of the clock generators can be accomplished without external logic.
