My company designed an electronic card using ADSP-TS201SABP-060 processor. ADSP-TS201SABP-060 uses Vdd=1.2V and Vdd-dram=1.6V.
However, the power designer of the electronic card mistakenly used Vdd=1.05V and Vdd-dram=1.5V.
The electronic card and ADSP processor work fine. Hundreds of products are in use, with no problem.
Do we have to call the products back to set true voltage level? Or no need because they work fine?
Answer provided through private support:
600MHz speed grade variants (060) should be powered as per the specifications provided in the datasheet. Failing to do so may result in device malfunctioning. We cannot guarantee proper device functionality over the whole temperature range, nor over extended periods of time. It may work, as seen, but we cannot guarantee that it will do so, unless the device is operated as per the specifications.
