请问用TMS320C6713BZDP300 替代TMS320C6713BZDP225，只需要工作在 225MHZ频率，那么内核电压（CVDD)是否可以用1.2V?

0 TMS320C6713BZDP300 芯片，工作在300MHZ时需要1.4V内核电压（CVDD)，现在想让他替代TMS320C6713BZDP225，只需要工作在 225MHZ频率，那么内核电压（CVDD)是否可以用1.2V? 0

0 还是用1.4v比较保险，请看下面的回复。 I just heard back from manufacturing. They indicate that 1.4V 300MHz devices are only tested to datasheet speeds at 1.4V -- there is no 100% guarantee that the -300 devices will operate at 225MHz at 1.2V. Personally, I think it should be fine using -300 devices for 1.2V/225MHz, but the customer needs to understand that they are using the drop-in replacement at their own risk.
